Check Tires When Cold:

Tire pressure should be checked when the tires are cold, meaning they haven’t been driven on for at least three hours. Driving heats up the tires, increasing the pressure and giving you an inaccurate reading.

Inflate to the Recommended Pressure:

If your tire pressure is below the recommended level, use an air compressor to inflate your tires. Many gas stations have air pumps available for public use. Ensure you inflate to the correct PSI as indicated in your owner’s manual or on the tire placard.

Don’t Forget the Spare:

Many people overlook their spare tire, but it’s crucial to keep it properly inflated as well. Check its pressure regularly to ensure it’s ready for use in an emergency.

Monitor for Changes:

Temperature changes can affect tire pressure. For every 10-degree Fahrenheit change in ambient temperature, tire pressure can increase or decrease by about 1 PSI. Be mindful of this, especially during seasonal transitions.

Adjust as Needed:

If the pressure deviates from the recommended levels, add or release air accordingly. Remember to recheck the pressure afterward.

Regular Maintenance:

Make tire pressure checks a routine part of truck maintenance, especially before long journeys or hauling heavy loads.
