Tire Pressure for 2005 GMC Sierra 3500 8.1L V8 Extended Cab Pickup (4 Door)

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 2005 GMC Sierra 3500 is relatively easy and important to do on a regular basis. Open the driver side door on your Sierra 3500 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 Sierra 3500 in the morning before the car has been used or when you have driven it for less than a mile. When you drive your Sierra 3500, 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.
