Did you know that the most important thing you can do to care for your tires and improve your fuel economy is to maintain the proper air pressure? Checking the tire pressure in your 2003 Hummer H2 is relatively easy and important to do on a regular basis. Open the driver side door on your H2 and look for a sticker that indicates what the tire pressure should be. Don't use the maximum pressure indicated on the sidewall of your tires. It is best to check the tire pressure on your H2 in the morning before the car has been used or when you have driven it for less than a mile. When you drive your H2, the air inside your tires warms up and expands, so to get an accurate reading, check the tire pressure when the car has not been driven recently.
Underinflated tires decrease the gas mileage of your H2, wear out faster and make the vehicle harder to steer, whereas overinflated tires blow out more easily, wear out faster and can cause unsafe handling dynamics. For these reasons and more - keeping your tires properly inflated on a regular basis is easy and important.
