GMC tire inflation pressures range around 28 to 80 psi based on the model, year, trim and original equipment tire sizes. Select from 56 GMC models built between 1983 and 2020 to find recommended tire pressure for GMC tires to improve fuel efficiency, extend tire life and drive safely.
It is vital to maintain correct tire inflation pressures for GMC 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 GMC to enjoy a safe and comfortable drive, save money on gas and keep auto insurance premiums low.
Recommended tire pressure for GMC is determined by the manufacturer based on its characteristics and original equipment tire sizes. You can find GMC recommended tire pressure in owner's manual or on a tire placard on the side of driver's door or door jam. GMC 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 GMC. GMC may have different recommended tire pressure settings for front and rear tires, especially if equipped with staggered tires.
If you replace GMC original equipment tires with optional or plus tire sizes, make sure to follow guidelines on how to apply tire load inflation tables when replacing GMC tires to find proper tire pressure for new tires. Always refer to the GMC owner’s manual for any specific safety advice regarding the application of replacement tires.
GMC tire pressure fluctuates with ambient temperatures, so when temperatures drop tires may lose approximately 1 psi of air pressure for every 10 degree Fahrenheit decrease in temperature. During winter GMC tires can be inflated 3 to 5 psi above the recommended tire pressure settings to compensate for lower temperatures. Never overinflate above psi indicated on tire sidewall. Make sure to check tire pressure regularly in the winter to keep tires properly inflated for a safe ride on snow and icy roads. Consult owner's manual for recommended winter tire pressure for GMC.
If your GMC is made after 2007, it should be equipped with tire pressure monitoring system that uses tire pressure sensors to alert the driver when tire pressure is low. When GMC low tire pressure warning light is on, check all tires for low air pressure and inflate as needed. Refer to owner's manual on how to reset GMC tire pressure monitoring system.
