• For Improved Handling:
  • 265/60R18 (for XLT trim)
  • 275/55R20 (for Lariat trim)
  • 285/45R22 (for King Ranch/Platinum/Limited trims)

These slightly wider, lower-profile options improve cornering stability and road feel during warm weather.

Summer Pressure Adjustments

Heat causes tire pressure to increase, requiring different management strategies:

• Standard Driving Conditions:
  • Maintain factory-recommended pressure
  • Check pressure in the morning before significant driving
  • Expect pressure to increase by 10-15 kPa during hot afternoons
• Highway Driving in Extreme Heat:
  • Consider setting pressure 5-10 kPa below maximum when cold to accommodate heat expansion
  • Never exceed the maximum pressure listed on the tire sidewall
  • Recheck pressure after extended high-speed driving in hot conditions

Heat Management Factors

Summer tire performance depends significantly on heat management:

• Wider tires dissipate heat more effectively, but may increase rolling resistance
• Lower aspect ratios (flatter sidewalls) reduce flex and heat buildup
• Higher speed ratings indicate better heat resistance during sustained high-speed driving

Proper inflation is crucial for managing heat buildup, especially during summer towing or hauling.

All-Season Performance Considerations

Versatile Tire Size Options

For F-150 owners seeking year-round performance without seasonal tire changes, these sizes offer the best compromise:

• Balanced Performance:
  • 265/70R17 (for XL/STX trims)
  • 275/65R18 (for XLT trim)
  • 275/60R20 (for Lariat trim)
  • 275/55R22 (for King Ranch/Platinum trims)

These moderate sizes provide reasonable performance across various conditions without excelling in any specific environment.

Seasonal Pressure Adjustments

All-season tires require regular pressure adjustments to accommodate temperature changes:

• Spring/Fall Transition Periods:
  • Check pressure weekly during rapid temperature fluctuations
  • Adjust to factory recommendations based on current morning temperatures
  • Consider 5 kPa higher than recommended during fall for the upcoming colder weather
• Maintenance Schedule:
  • Perform complete pressure checks monthly
  • Adjust for significant temperature changes (±10°C)
  • Recalibrate TPMS sensors after seasonal adjustments

All-Weather vs. All-Season

True all-weather tires (distinguished from standard all-season) offer enhanced year-round performance:

• All-Weather Advantages:
  • Three-peak mountain snowflake rating for winter capability
  • More aggressive tread patterns for varied conditions
  • Compound formulations that perform reasonably well in both hot and cold extremes

These specialized tires typically perform best when maintained at factory-recommended pressures with seasonal adjustments.

Wet Weather Performance

Optimal Wet Weather Sizes

Rainy conditions demand tires that effectively evacuate water to prevent hydroplaning:

• Enhanced Wet Traction:
  • 265/70R17 (for XL/STX trims)
  • 265/60R18 (for XLT trim)
  • 275/60R20 (for Lariat trim)

These sizes balance adequate width for stability with sufficient tread width for water evacuation.

Wet Weather Pressure Adjustments

Proper inflation is critical for wet-weather performance:

• Light to Moderate Rain:
  • Maintain factory-recommended pressure
  • Ensure even wear across the tread face
  • Check pressure monthly to prevent underinflation
• Heavy Downpours and Standing Water:
  • Consider 5-10 kPa above recommended pressure to reduce hydroplaning risk
  • Return to normal pressure when conditions improve
  • Never exceed maximum sidewall pressure

Hydroplaning Prevention

Tire pressure significantly affects hydroplaning resistance:

• Underinflated tires increase hydroplaning risk by flattening the tread pattern
• Properly inflated tires maintain optimal tread channel shape for water evacuation
• Slightly overinflated tires can reduce hydroplaning but compromise traction and comfort

The ideal balance for wet conditions typically falls at or slightly above the manufacturer’s recommended pressure.

Off-Road Tire Considerations

Optimal Off-Road Sizes

For F-150 owners who venture off pavement, these tire sizes enhance capability:

  • 285/75R17 (for XL/STX with levelling kit)
  • 295/70R18 (for XLT with levelling kit)
  • 315/70R17 (for Raptor trim)

These taller, wider options provide increased ground clearance and contact patch for off-road traction.

Off-Road Pressure Adjustments

Off-road driving often requires significant pressure adjustments:

• Gravel and Dirt Roads:
  • Reduce pressure by 10-15 kPa from highway recommendations
  • Maintain at least 200 kPa for P-metric tires
  • Return to normal pressure when returning to paved roads
• Sand, Mud, and Rocks:
  • Reduce pressure by 20-30 kPa for improved traction
  • Never go below 140 kPa for short-duration extreme terrain
  • Reinflate immediately after challenging sections

Terrain-Specific Considerations

Different off-road environments benefit from specific pressure settings:

• Sand: Lower pressure (140-170 kPa) creates a longer footprint for flotation
• Mud: Moderate reduction (170-200 kPa) allows tread to flex and clean itself
• Rocks: Slightly reduced pressure (200-220 kPa) improves conformity to obstacles

Always carry a portable air compressor when off-roading to adjust pressure as conditions change.

Load and Towing Considerations

Heavy-Duty Tire Sizes

When regularly carrying heavy loads or towing, consider these more robust tire options:

• Enhanced Load Capacity:
  • LT265/70R17 (for XL/STX trims)

  • LT275/60R20 (for Lariat trim)

The “LT” designation indicates Light Truck construction with reinforced sidewalls and higher load capacities.

Load-Based Pressure Adjustments

Proper inflation is critical when carrying cargo or towing:

• Empty or Light Load:
  • Follow door placard recommendations
  • Maintain even pressure front to rear
  • Check pressure when cold before loading
• Heavy Cargo or Towing:
  • Increase rear tire pressure by 10-20 kPa
  • Never exceed maximum sidewall pressure
  • Return to normal pressure when unloaded

Payload Distribution Effects

How weight is distributed affects optimal tire pressure:

• Evenly distributed cargo requires moderate pressure increases
• Tongue weight from trailers primarily affects rear tire pressure
• Fifth-wheel towing affects all tires more evenly

Consult your F-150 owner’s manual for specific pressure recommendations based on load.

Tire Pressure Monitoring System (TPMS)

  • Readings may vary slightly from actual pressure gauge measurements
• Temperature Compensation:
  • TPMS readings fluctuate with temperature changes
  • The system is calibrated at 20°C (68°F)
  • Readings will be lower in cold weather and higher in warm weather

Seasonal TPMS Considerations

When adjusting seasonal pressure, keep these TPMS factors in mind:

• Winter Adjustments:
  • TPMS may show lower pressure readings in cold mornings
  • Allow vehicle to warm up before becoming concerned about low readings
  • Use a quality pressure gauge for accurate cold inflation
• Summer Adjustments:
  • TPMS may show increased pressure after driving in hot conditions
  • Avoid reducing pressure when tires are hot
  • Check and adjust pressure when tires are cold

Keep Your Ford F-150 Safe in any Season

Selecting the right tire size and maintaining proper pressure for your Ford F-150 significantly impacts performance, safety, and comfort across various weather conditions.
