The recommended PSI (pounds per square inch) for tires 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 some tips to help you find the correct tire pressure for your vehicle:
-
Check the owners manual: 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.
-
Check the tire pressure: Use a tire pressure gauge to 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.
-
Adjust tire pressure if needed: If the tire pressure is too low, use an air compressor to add air until it reaches the recommended PSI. If the pressure is too high, release air.
-
Check tire pressure when cold: Temperature has a direct effect on your tires’ air pressure, so for an accurate PSI reading, make sure to check the pressure when tires are cold. In general, tires lose or gain 1 PSI for every 10℉ change in temperature. That’s why it’s recommended that you check air pressure every other time you stop to fill up your gas tank. Keep in mind that many vehicles have different tire pressures on the front and rear axle. And don’t forget to check the pressure in your spare tire.
-
Consider load requirements: Some vehicles have different recommended inflation pressures for the front and rear tires, and sometimes a higher pressure (usually for the rear) will be listed for if you’re carrying a heavy load.
In general, most passenger cars PSI requirement will be between 30 to 35 PSI, but several vehicles fall outside of that range, and every vehicle will have specific requirements. Always let the tires cool down for fifteen minutes before checking the tire pressure after driving the vehicle. If you add air to a hot tire after driving, add 5 PSI, then make the necessary adjustment the next d...
