It is vital to maintain proper tire inflation pressures for 2015 GMC Sierra 1500 tires. Low tire pressure and underinflated tires can lead to uneven and excessive tire wear, poor handling and reduced fuel economy. High tire pressure and overinflated tires can result in reduced traction, poor braking and can even be a cause of a tire blowout. Check tire pressure regularly and maintain correct tire inflation for 2015 GMC Sierra 1500 to enjoy a safe and comfortable drive.

Recommended tire pressure for 2015 GMC Sierra 1500 is determined by the manufacturer based on its characteristics and original equipment tire sizes. You can find 2015 GMC Sierra 1500 recommended tire pressure in owner's manual or on a tire placard on the side of driver's door or door jam. 2015 GMC Sierra 1500 tire inflation will be listed in psi (pounds per square inch), bar or kPa (kilopascals). Keep in mind that tire inflation listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not necessarily the recommended tire pressure for 2015 GMC Sierra 1500. Your 2015 GMC Sierra 1500 may also have different recommended tire pressure settings for front and rear tires, especially if equipped with staggered tires.

To check 2015 GMC Sierra 1500 tire pressure you will need to know its recommended tire inflation and a tire pressure gauge. Check tire pressure when tires are "cold" using quality tire pressure gauge.
