Essential Tire Pressure Checks for Agricultural Operations

For agricultural equipment operators, tire pressure is far more than a maintenance checkbox—it's a critical factor that directly impacts soil health, fuel costs, and equipment longevity. Proper tire inflation stands at the intersection of operational efficiency and field productivity, yet it remains one of the most overlooked aspects of farm equipment management.

Whether you're operating a small utility tractor or managing a fleet of large implements, understanding how to check, adjust, and maintain optimal tire pressure will not only extend the life of your expensive agricultural tires but also protect your most valuable asset: your soil.

Why Agricultural Tire Pressure Matters

Impact on Soil Compaction & Crop Yields

Every time your equipment rolls across a field, it creates an invisible footprint beneath the surface. The weight of agricultural machinery compresses soil particles, potentially restricting root growth, reducing water infiltration, and limiting nutrient availability. The severity of this compaction is directly influenced by your tire pressure settings.

Overinflated tires concentrate the machine’s weight onto a smaller contact area, increasing ground pressure and driving compaction deeper into the soil profile. According to research from Penn State Extension, just 10 PSI of overinflation can increase subsoil compaction depth by up to 8 inches—affecting root penetration far below the surface.

The impact on yields is equally significant. Field trials in North Dakota demonstrated that reducing tire pressure from 35 PSI to 12-15 PSI increased corn yields by up to 11% in clay-loam soils. This yield boost comes primarily from improved root development, better water infiltration, and enhanced nutrient uptake in properly managed soils.

Fuel Efficiency & Operational Costs

Tire pressure directly influences rolling resistance—the energy required to keep your equipment moving. Improper inflation forces your engine to work harder, burning more fuel with every pass across your fields.

Underinflated tires create excessive flexing in the sidewalls, increasing rolling resistance and fuel consumption. Overinflated tires reduce the contact patch, causing slippage that wastes power and fuel. Studies show that optimizing tire pressure can improve fuel efficiency by 5-10%, representing substantial savings across a season’s worth of fieldwork.

Beyond fuel savings, proper inflation significantly impacts your maintenance budget. Underinflated tires wear faster on the shoulders and can overheat during extended operation. According to tire manufacturers, running even 20% below recommended pressure can reduce tire life by up to 25%, turning a six-year investment into a four-year expense.

Tire Longevity & Equipment Performance

Agricultural tires represent a significant investment, often costing thousands of dollars per set. Maintaining proper inflation is the single most important factor in maximizing their service life.

Incorrect pressure accelerates wear patterns that cannot be reversed. Overinflated tires develop premature center wear, while underinflated tires experience excessive shoulder wear and sidewall stress. Both conditions reduce traction, hamper performance, and ultimately lead to early replacement.

Additionally, improper inflation affects handling characteristics. Overinflated tires bounce over field irregularities rather than flexing with them, reducing operator comfort and increasing stress on equipment components. Underinflated tires can cause sluggish steering response and instability, particularly during road transport at higher speeds.

Safety Risks of Improper Inflation

Beyond operational considerations, tire pressure directly impacts safety. Underinflated tires are more susceptible to sidewall damage and sudden failure, particularly when carrying heavy loads or operating at higher speeds. This can lead to dangerous situations for operators and potential damage to expensive equipment.

Overinflated tires offer less cushioning against impacts from rocks or field obstacles, increasing the risk of punctures and blowouts. They also provide less stability on uneven terrain, increasing the risk of rollovers on slopes or during sharp turns.

Regular pressure checks are an essential safety measure that protects both operators and equipment from preventable incidents.

How to Check Agricultural Tire Pressure: Step-by-Step Guide

Tools Needed: Analog vs. Digital Gauges, Valve Extensions

Checking agricultural tire pressure requires specialized equipment beyond what you might use for passenger vehicles. Here’s what you’ll need:

• Pressure gauge: Choose between analog (dial) or digital models. While analog gauges are typically more durable in farm environments, digital gauges offer greater precision (±0.5% accuracy vs. ±3% for analog) and can detect subtle 0.1 PSI changes that are critical for modern VF tire setups. For most applications, select a gauge rated up to 100 PSI with clearly marked increments.
• Valve extensions: These are essential for checking dual wheel setups where the inner valve stems may be difficult to access. Rigid extensions provide easier access and greater durability for regular use.
• Portable air compressor: For field adjustments, a 12V compressor capable of delivering at least 5 CFM (cubic feet per minute) at 150 PSI is ideal. Portable farm compressors with sufficient capacity allow you to make immediate corrections without returning to the workshop.
• Valve core tool: This inexpensive tool allows you to check, remove, and replace valve cores to address slow leaks and ensure proper sealing.

Investing in quality equipment ensures accurate readings and efficient adjustments, especially during critical planting and harvesting windows when time constraints are significant.

Cold Pressure Checks: Timing & Best Practices

The most accurate tire pressure readings come from “cold” tires that haven’t been in operation for at least three hours. During operation, friction generates heat that increases air pressure, potentially giving misleading readings that could lead to underinflation once the tires cool down.

According to tire pressure best practices, the ideal time to check pressure is in the morning before beginning field operations. This provides the most accurate baseline measurement and allows time for adjustments before work begins.

Follow these steps for proper pressure checks:

1. Remove the valve cap and store it in a secure location
2. Quickly press the gauge onto the valve stem to form a tight seal
3. Hold the gauge firmly until the reading stabilizes
4. For digital gauges, note the digital readout; for analog gauges, read where the pointer indicates on the dial
5. Replace the valve cap securely after checking or adjusting pressure

Checking pressure weekly is a minimum recommendation, with additional checks after significant temperature changes, when changing implements, or before critical fieldwork phases.

Interpreting Manufacturer Pressure Charts

Manufacturer pressure charts may initially seem complex, but they provide essential guidance for your specific equipment and operating conditions. These charts typically organize information by:

• Tire size and construction (radial or bias)
• Load weight (per tire/axle)
• Speed rating
• Application type (field vs. road)

To interpret these charts:

1. Identify your exact tire size and type
2. Determine the weight carried by each tire (often requiring equipment weighing)
3. Select the appropriate column based on speed (typically separated into field and road speeds)
4. Find the intersection point to determine the minimum recommended pressure

Many manufacturers now offer digital tools to simplify this process. The Michelin inflation calculator provides axle weight-based pressure recommendations for over 100 implement types, eliminating guesswork from the process.

Remember that these charts provide minimum required pressures—adding 2-3 PSI above these recommendations provides a safety margin for temperature fluctuations and minor weight variations.

Adjusting Pressure for Dual Tires & Large Equipment

Dual tire setups require special attention to ensure even load distribution and prevent premature wear. Both tires in a dual configuration should maintain identical pressure to share the load equally.

When checking dual tires:

• Use valve extensions to access inner tire valves without removing wheels
• Check both tires consecutively using the same gauge for consistency
• Adjust pressure in both tires to match exactly, even if both are within acceptable ranges

For large equipment with multiple axles, pressure may vary between axles based on weight distribution. Front axles typically carry different loads than rear or trailing axles, requiring different inflation pressures. Consult your equipment manual for axle-specific recommendations.

A field pressure adjustment demonstration shows that proper dual wheel adjustment typically takes about 20 minutes—time well spent considering the performance benefits and reduced wear.

Optimal Tire Pressure for Different Operations

Plowing vs. Harvesting

Different field operations place varying demands on your equipment, often requiring specific pressure adjustments for optimal performance and soil protection.

For primary tillage operations like plowing that require maximum traction:

• Reduce pressure to the lower end of the recommended range
• This increases the tire footprint, improving grip and reducing slippage
• Lower pressure also reduces draft requirements, potentially saving 5-7% in fuel costs

For harvesting operations with heavy loads:

• Adjust pressure based on the fully loaded weight of the equipment
• Consider using higher pressures when bins are full, potentially adjusting mid-day as loads increase
• If your harvester will travel on roads between fields, consider a compromise pressure that performs adequately in both environments

Planting requires particularly careful pressure management, as overcompaction during planting can limit yield potential regardless of subsequent practices.

Equipment-Specific Guidelines: Tractors, Sprayers, Combines

Different equipment types have unique pressure requirements based on their design, weight distribution, and intended use:

Tractors: Front tires typically carry 30-40% of the machine weight and may require different pressure than rear tires. Weight transfer during pulling operations can significantly increase the load on rear tires, requiring adjustments when attaching heavy implements.

Sprayers: Modern sprayers present unique challenges due to their combination of heavy tanks and high road speeds. A sprayer pressure study found that reducing pressure from 35 PSI to 17 PSI decreased rut depth by 64% in soybean fields while maintaining adequate stability.

Combines: The substantial weight of combines, especially when grain tanks are full, requires careful pressure management. Front (drive) tires carry most of the load and should be inflated according to the maximum anticipated weight. Remember that a full grain tank can add several tons to the total weight.

Always consult your equipment manual for specific recommendations, as designs vary significantly between manufacturers and models.

Load-Based Calculations & Inflation Tables

The most accurate method for determining optimal tire pressure involves load-based calculations using manufacturer-provided tables. This approach accounts for the actual weight carried by each tire rather than relying on general guidelines.

To perform a load-based calculation:

1. Weigh your equipment in field-ready condition (including full tanks, attached implements, etc.)
2. Determine the weight carried by each axle (ideally by weighing each side separately)
3. Divide the axle weight by the number of tires to find per-tire load
4. Consult the load/inflation table for your specific tires
5. Find the minimum pressure required for your calculated load

For convenience, many manufacturers now offer mobile apps or online calculators that simplify this process. These tools can provide custom recommendations based on your specific configuration and conditions.

Radial vs. Bias Tires

Radial and bias-ply tires require different inflation pressures even when carrying identical loads. Understanding these differences is essential for proper inflation management.

According to a tire evolution study, radial tires reduce mean soil stress by 18-22% compared to bias-ply at equal pressures. This advantage comes from the radial tire’s construction, which allows the sidewall to flex independently of the tread.

Key differences include:

• Radial tires: Generally operate at lower pressures (15-25% less than bias tires for the same load). Their flexible sidewalls create a larger footprint, reducing ground pressure and improving traction.
• Bias-ply tires: Require higher inflation pressures to support equivalent loads. Their more rigid construction provides stability but results in a smaller contact area and higher ground pressure.

Always use the inflation table specific to your tire type, as using bias-ply guidelines for radial tires will result in significant overinflation and compromised performance.

Seasonal & Environmental Adjustments

Winter vs. Summer Pressure Strategies

Seasonal temperature fluctuations significantly impact tire pressure and require proactive management. As a rule of thumb, tire pressure changes approximately 1 PSI for every 10°F (5.6°C) change in ambient temperature.

In winter months:

• Add 2-3 PSI above normal operating pressure to account for pressure drops in cold weather
• Check pressure more frequently, especially during sudden temperature changes
• Store unused equipment with slightly higher pressure to compensate for gradual pressure loss

In summer months:

• Monitor for potential overinflation, especially during heatwaves
• Check pressure in the coolest part of the morning for accurate readings
• Adjust downward if extended high-temperature operation is expected

When storing equipment seasonally, maintain proper inflation to prevent flat spots and sidewall cracking. If possible, elevate the machine to reduce weight on the tires during extended storage periods.

Managing Temperature-Related Pressure Fluctuations

Daily temperature changes can cause significant pressure variations, particularly during spring and fall when temperature swings of 30°F or more are common between night and morning.

To manage these fluctuations:

• Establish a baseline pressure during average temperature conditions
• Add 1 PSI for every 10°F drop below your baseline temperature
• Subtract 1 PSI for every 10°F increase above your baseline temperature
• Consider using nitrogen inflation for more stable pressure

In extreme conditions, such as moving from an unheated storage building to operation in very cold temperatures, allow equipment to acclimate before making final pressure adjustments.

Soil Type Considerations: Sand, Clay & Loam

Different soil types respond uniquely to tire pressure, requiring specific adjustments for optimal performance and minimal compaction:

Sandy soils: These drain quickly but are prone to rutting. Lower pressure (at the minimum recommended) increases flotation and reduces sinkage.

Clay soils: Highly susceptible to compaction, especially when wet. Reducing pressure by 10-15% from road settings can significantly decrease compaction risk. Avoid field operations when clay soils are wet, as even optimal tire pressure cannot prevent compaction in saturated conditions.

Loam soils: Generally more forgiving than clay but still benefit from proper pressure management. Moderate pressure settings typically provide a good balance between traction and compaction protection.

When working with variable soil types, consider adjusting pressure between fields if significant texture differences exist. The extra time spent making these adjustments will pay dividends in improved soil health and crop performance.

Wet vs. Dry Field Conditions

Moisture content dramatically affects how soil responds to equipment traffic, making it a critical factor in tire pressure decisions.

In wet conditions:

• Reduce pressure to the lowest safe level for your load to maximize flotation
• Consider postponing operations if significant rutting occurs despite pressure adjustments
• If operations must continue, follow consistent traffic patterns to limit compacted areas

In dry conditions:

• Higher pressures may be acceptable as compaction risk is reduced
• However, very dry soils can be pulverized by traffic, destroying structure
• Moderate pressures generally provide the best balance for soil protection

Efficiency analysis data suggests the right tire pressure can be the difference between operating at 6 mph in wet fields versus just 4 mph with overinflated tires—a major boost in productivity during critical weather windows.

Tools & Technologies for Precision Pressure Management

Digital Gauges vs. TPMS (Tire Pressure Monitoring Systems)

The evolution from manual pressure checks to automated monitoring represents a significant advancement in agricultural tire management.

Digital pressure gauges offer substantial advantages over traditional analog models, including:

• Higher accuracy (typically ±0.5% vs. ±3% for analog gauges)
• Easy-to-read displays that eliminate interpretation errors
• Enhanced durability with operating ranges from -40°C to 85°C
• Ability to measure in multiple units (PSI, kPa, bar) without conversion

Tire Pressure Monitoring Systems (TPMS) take this further by providing continuous monitoring through sensors mounted on each valve stem. These systems:

• Provide real-time pressure and temperature readings to the operator
• Alert operators to gradual or sudden pressure losses
• Monitor multiple tires simultaneously
• Store historical data for tracking long-term trends

For operations with multiple operators, TPMS can ensure consistent monitoring that doesn’t rely on individual diligence or technique.

Central Tire Inflation Systems (CTIS) for On-the-Go Adjustments

Central Tire Inflation Systems (CTIS) represent the pinnacle of tire pressure management, allowing operators to adjust pressure directly from the cab while operating.

These systems typically include:

• An onboard air compressor or connection to the vehicle’s air system
• Rotary air seals at each wheel
• Control lines running to each tire
• A control panel in the cab for operator adjustments

The benefits of CTIS are substantial:

• Immediate adaptation to changing field conditions or road transport
• Preset programs for different operations
• Reduced operator effort and increased compliance with pressure guidelines
• Extended tire life through consistent optimal inflation

Some yield improvement data indicates farms utilizing CTIS can see an average 7% yield gain—often paying for the system within a few seasons.

Portable Compressors & Valve Maintenance Kits

For operations not ready to invest in CTIS technology, quality portable equipment provides a practical alternative for field adjustments.

Essential portable tools include:

• High-volume portable compressors: Field inflation tools capable of delivering at least 5 CFM at 150 PSI allow for relatively quick pressure adjustments. Look for 12V models that can operate from tractor or vehicle power systems.
• Extended hoses: Long air hoses (25+ feet) provide the reach needed to access all tires without repositioning the compressor.
• Accurate pressure gauges: Digital gauges with integrated inflation/deflation capabilities streamline the adjustment process.
• Valve core tools: Quick replacement of damaged valve cores—common in harsh agricultural conditions—keeps tires sealed.

A complete valve maintenance kit should include replacement cores, valve caps, and seals to address common issues in the field.

IoT Solutions for Real-Time Pressure Tracking

The Internet of Things (IoT) has entered the agricultural tire management space, offering sophisticated remote monitoring capabilities.

These advanced systems typically feature:

• Wireless sensors mounted on each tire
• Cloud-based data storage and analysis
• Mobile applications for remote monitoring
• Integration with farm management software
• Predictive maintenance alerts based on pressure trends

The advantages include:

• Monitoring entire fleets from a single dashboard
• Historical data analysis to identify recurring issues
• Early warning of developing problems before they cause downtime
• Simplified scheduling based on actual conditions rather than time intervals

For large operations, these systems ensure consistent monitoring without relying on manual record-keeping during busy periods.

Troubleshooting Common Pressure Issues

Identifying Under/Over-Inflation: Wear Patterns & Symptoms

Tire wear patterns provide valuable diagnostic information about inflation issues, often revealing problems before they lead to tire failure.

Signs of overinflation include:

• Accelerated wear in the center of the tread
• Reduced traction and increased slippage
• A harder, less comfortable ride
• Increased sensitivity to impacts and obstacles

Signs of underinflation include:

• Excessive wear on the outer edges of the tread
• Sidewall cracking or bulging
• Increased rolling resistance and fuel consumption
• Heat buildup after prolonged operation

Performance symptoms may include:

• Uneven field cultivation depth
• Steering pull to one side
• Excessive vibration at certain speeds
• Reduced fuel efficiency

Regular visual inspection allows for early intervention before significant damage occurs.

Repairing Slow Leaks & Valve Failures

Slow leaks are common in agricultural settings due to harsh conditions and extended service expectations.

Common causes of slow leaks include:

• Damaged or contaminated valve cores
• Rim corrosion that prevents proper sealing
• Small punctures in the tread area
• Bead seating issues, particularly after field repairs

Basic repair procedures:

1. Identify the source of the leak using soapy water or by submerging tubeless valves in water
2. For valve issues, clean or replace the valve core using a proper valve tool
3. For rim sealing issues, break the bead, clean the rim surface, and apply bead sealer before reinflation
4. For punctures, confirm the damage is repairable (usually in the tread area) before proceeding

Always follow manufacturer guidelines, as modern tire designs may have specific repair limitations, especially for high-speed-rated tires.

Managing Pressure Differences in Dual Configurations

Dual tire configurations require equal pressure to ensure proper load distribution and prevent premature wear.

When managing duals:

• Always check and adjust both tires in a dual set during the same session
• Use the same pressure gauge for both tires
• Ensure pressure differences never exceed 2 PSI
• Match tire diameters within manufacturer specifications when mounting new duals

Pressure imbalances can cause one tire to carry more load, accelerating wear and reducing traction. Valve extensions that position both stems on the outer wheel can simplify checks.

When to Replace vs. Repair Tires

Making informed decisions about tire replacement versus repair can prevent costly failures and unsafe conditions.

Generally, tires should be replaced when:

• Tread wear exceeds 80% of original depth
• Significant sidewall damage is present
• Multiple repairs have been made on the same tire
• Irregular wear patterns compromise performance

Repairs may be appropriate when:

• Punctures are limited to the tread area and smaller than 1/4" diameter
• No significant sidewall damage is present
• Sufficient tread remains to justify the repair cost
• The repair can be sealed to prevent moisture intrusion

Always consult with a tire professional when significant damage occurs, as improper repairs can lead to failures at high speeds or under heavy loads.

Economic & Environmental Benefits of Proper Pressure

Case Studies: Fuel Savings & Yield Improvements

The economic benefits of proper tire pressure management are well-documented across various farming operations:

Case Study 1: A 3,000-acre corn and soybean operation in Iowa implemented a Central Tire Inflation System on their primary tillage tractor. They reduced tire pressure from 24 PSI to 14 PSI for field operations while maintaining 24 PSI for road transport. Results showed:

• 7% average yield increase across all acres
• 12% reduction in fuel consumption
• 15% decrease in tire wear over a 3-year period
• System payback period of 2.3 years

Case Study 2: A 1,500-acre wheat farm in Saskatchewan used portable compressors and digital gauges for rigorous pressure checks. Two-year results showed:

• 5.2% fuel savings across all operations
• 4.8% yield increase attributed to reduced soil compaction
• Return on investment within the first year from fuel savings alone

Whether using advanced technology or disciplined manual management, the economic benefits of proper tire pressure are substantial and achievable for farms of various sizes.

ROI of Automated Systems (CTIS/TPMS)

Investing in automated pressure management technology represents a significant upfront cost but offers strong returns:

Central Tire Inflation Systems (CTIS):

• Typical installation cost: $15,000-$30,000 depending on complexity
• Annual maintenance cost: $500-$1,000
• Lifespan: 8-10 years with proper maintenance

ROI typically comes from:

• Fuel savings of 5-15%
• Yield increases of 3-7%
• Extended tire life of 15-25%
• Reduced labor costs for pressure management

Tire Pressure Monitoring Systems (TPMS):

• Typical cost: $2,000-$5,000 based on the number of tires monitored
• Annual maintenance: $200-$500 (sensor replacement)
• Lifespan: 5-7 years for the base system

The ROI calculation for TPMS focuses on preventing tire damage from underinflation and reducing downtime. A crop yield case study showed a 12-15% yield increase when pressure was reduced from 35 PSI to 12-15 PSI in clay-loam soils—a significant return on investment.

Reducing Soil Degradation & Carbon Footprint

Beyond direct economic benefits, proper tire pressure management supports environmental sustainability:

Soil health improvements:

• Reduced compaction preserves soil structure
• Enhanced water infiltration reduces erosion
• Improved root development aids nutrient cycling
• Less disruption of soil aggregates preserves organic matter

Carbon footprint reduction:

• Lower fuel consumption reduces CO2 emissions
• Healthier soils enhance carbon sequestration
• Less tillage needed to remediate compaction
• Extended tire life conserves manufacturing resources

A typical 1,000-acre operation can reduce carbon emissions by several metric tons annually through optimized tire pressure management, equivalent to taking passenger vehicles off the road permanently.

Compliance with Sustainable Farming Certifications

Many agricultural certification programs recognize tire pressure management as a component of sustainable farming:

• USDA Conservation Programs: Some NRCS programs incentivize practices that reduce soil compaction.
• Sustainable Agriculture Certifications: Soil health metrics in various certifications are influenced by compaction management.
• Carbon Credit Programs: Emerging markets may reward practices that reduce emissions and enhance soil carbon sequestration.

Documenting your tire pressure management protocol can support compliance with these programs and potentially provide access to premium markets or financial incentives.

Advanced Strategies for High-Efficiency Farms

Integrating Pressure Management with Precision Agriculture

Forward-thinking operations increasingly integrate tire pressure management with broader precision agriculture systems:

• GPS integration: Automated pressure adjustments based on field zones
• Telematics: Remote monitoring and adjustment through farm management software
• Automated documentation: Recording pressure changes alongside other operational data

These integrations enhance consistency and reduce operator workload while ensuring optimal pressure for all field conditions.

VF/IF Tires & Low-Pressure Field Operations

Very High Flexion (VF) and Improved Flexion (IF) tire technologies represent major advancements in agricultural tire design. These tires can carry the same load as standard radials with significantly lower air pressure or more load at the same pressure, providing:

• Exceptional flotation in wet conditions
• Minimized compaction even with heavy equipment
• Improved traction and reduced slippage
• Fuel savings through reduced rolling resistance

While VF/IF tires cost more initially, they often justify the premium through extended service life and superior performance for soil health and sustainability.

Ballasting Techniques for Weight Distribution

Proper ballasting complements tire pressure management to optimize traction and minimize soil impact:

• Liquid ballast: Adds weight inside the tire but requires adjusted pressure calculations
• Wheel weights: Precisely place weight without affecting internal tire pressure
• Front weights: Balance implements and prevent front-end lightening

Strategies include seasonal adjustments, task-specific configurations, and calculating optimal weight distribution. Always recalculate tire pressure requirements after changing ballast configurations.

Future Trends: Smart Tires & AI-Driven Adjustments

The future of agricultural tire management includes emerging innovations:

• Self-adjusting tires: Systems that sense load and conditions, adjusting pressure automatically
• Airless tire designs: Honeycomb or spoke structures eliminating air pressure concerns
• AI prediction models: Tools that forecast optimal pressure based on weather, soil data, and planned operations
• Tire-integrated sensors: Advanced monitoring of temperature, deflection, and wear metrics

Staying informed about these options helps operations maintain an edge in efficiency and soil management.

FAQs: Addressing Farmer Concerns

"How often should I check pressure in peak season?"

During planting and harvest, checking tire pressure weekly is a minimum recommendation. Brief visual inspections should be done daily, with complete checks:

• Before beginning a new field or changing operation types
• After significant weather changes (temperature swings of 20°F or more)
• When changing implements or load configurations
• If any unusual handling or visible tire deformation is observed

A five-minute pressure check can prevent hours of downtime from tire failures during critical windows.

"Can I use automotive gauges for ag tires?"

Standard automotive tire gauges are generally unsuitable for agricultural tires:

• Limited pressure range
• Insufficient durability for farm environments
• Inadequate accuracy for modern agriculture
• Often unable to form a proper seal on large-diameter valve stems

Invest in gauges designed for agricultural and commercial use, with a higher pressure range, durable construction, and the right fittings.

"Solving persistent pressure loss in old tires"

Older tires often develop slow leaks that can be frustrating to address. Common causes include:

Valve issues: Replace the valve core completely, apply a valve cap with a rubber seal, or consider sealed valve extensions.

Rim issues: Clean the bead area thoroughly, apply bead sealer, and inspect for rim cracks or corrosion.

Porosity issues: Some older tires allow gradual air migration through worn rubber. Using tubes or commercial sealants may provide a temporary fix.

If these steps fail, replacement may be the most cost-effective option, especially if the tires show significant wear.

"Best pressure for mixed road/field use"

Equipment that regularly transitions between road and field use often requires compromise. Without a Central Tire Inflation System:

1. Prioritize pressure settings based on where you spend most of your operational time.
2. Adjust for higher road speeds if necessary, never running low field pressures on highways.
3. Consider load variations, such as an empty vs. full grain cart.

A practical solution for short-duration mixed use is to calculate the minimum safe pressure for the heaviest load at road speed, then add a margin of 2-3 PSI. If prolonged field work is planned, reduce pressure as needed and restore it before longer road travel.

For frequent transitions, a Central Tire Inflation System automates these adjustments. Complete selection of premium tractor tires may help optimize performance, but proper inflation remains the single most important factor.
