Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 1997 GMC Yukon is printed on the driver-side door jamb sticker â always defer to that value, not to the maximum pressure printed on the tire sidewall. Check pressure monthly and before long trips; under-inflation by 20% can reduce tread life by 25%.
