Check Tire Pressure

Check your tires, including the spare tire, at least once a month.

How to Check

Use a good quality tire pressure gauge to check tire pressure. You cannot tell whether your tires are properly inflated just by looking at them. Radial tires may look properly inflated even when they are under-inflated.

Remove the cap from the tire valve stem. Press the tire pressure gauge firmly onto the valve to take a reading. If the cold tire pressure matches the recommended tire pressure on the tire and loading information label, no further adjustment is necessary. If the pressure is low, add air until the recommended pressure is reached.

Be sure to reinstall the valve stem caps. Without the valve cap, dirt or moisture may enter the valve core and cause air leakage. If a valve cap is missing, install a new one as soon as possible.

If you overinflate a tire, release air by pressing the metal pin in the center of the tire valve. Recheck the tire pressure with a tire pressure gauge. Be sure to reinstall the valve stem caps. Without the valve cap, dirt or moisture may enter the valve core and cause air leakage. If a valve cap is missing, install a new one as soon as possible.
