The recommended tire pressure for your vehicle can vary depending on the vehicle, tire size, and load requirements. It is essential to regularly check and maintain the correct PSI level to maximize tire lifespan and maintain a safe driving experience. Here are the steps to follow to determine the correct tire pressure for your vehicle:

1. Check tire pressure when your tires are cold: The friction and heat caused by driving can affect tire pressure. It is recommended to check your tire pressure before or at least three hours after driving.

2. Find the recommended PSI for your vehicle: Nearly every vehicle lists the manufacturer-recommended tire pressures on a sticker affixed to the driver-side door jamb, which is the body pillar the door locks into. It could also be on the rear edge of the door itself, in the glove box, or on the inside of the fuel-filler door. You can also find it in the owner’s manual.

3. Remove the valve cap: Unscrew the valve cap on the tires valve stem. Keep the cap in a safe place.

4. Attach the tire pressure gauge: Press the gauge firmly onto the valve stem to get an accurate reading. You may hear a hissing sound, which is normal.

5. Read the tire pressure: Compare the gauges tire pressure reading to the recommended PSI for your vehicle. If the pressure is too high or too low, it will need to be adjusted.

6. Adjust tire pressure if needed: If the tire pressure is too low, use an air compressor or a gas station air pump to add air to the tire. If the tire pressure is too high, use the gauge to release air until it reaches the recommended PSI.

It is important to note that the recommended tire pressure is a cold inflation pressure, which means the pressure check should be done after the vehicle has been sitting in the shade for a while. The pressures listed are for the tire size that originally came on the vehicle, which is also listed on the sticker. If different-sized wheels and tires have been installed, the listed pressures won’t necessarily be optimal. Additionally, always let the tires cool down for fifteen minutes before checking the tire pressure after driving the vehicle. Or, check the tire pressures first thing before driving the vehicle. If you add air to a hot tire after driving, add 5 PSI, then make the necessary adjustment the next day when the tires are cool. Normal operating pressure is 3 to 5 PSI above the cold pressure.
