Recommended tire pressure for 1998 GMC Sonoma is determined by the manufacturer based on its characteristics and original equipment tire sizes. You can find 1998 GMC Sonoma recommended tire pressure in owner's manual or on a tire placard on the side of driver's door or door jam. 1998 GMC Sonoma 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 1998 GMC Sonoma. 1998 GMC Sonoma may have different recommended tire pressure settings for front and rear tires, especially if equipped with staggered tires.

To check 1998 GMC Sonoma tire pressure you will need to know its recommended tire inflation and a tire pressure gauge. Check tire inflation when tires are "cold" and have not been driven for at least 3 hours. Adjust 1998 GMC Sonoma tire inflation to the recommended tire pressure levels as needed by adding air with a tire inflator.

If you replace 1998 GMC Sonoma original equipment tires with optional or plus tire sizes, make sure to follow guidelines on how to apply tire load inflation tables when replacing 1998 GMC Sonoma tires to find proper tire pressure for new tires.

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 1998 GMC Sonoma.
