GMC Tire Pressure | GMC Sonoma Tire Pressure | 1999 GMC Tire Pressure

It is vital to maintain proper tire pressure for 1999 GMC Sonoma tires. Low tire pressure will result in tire underinflation while high tire pressure will result in tire overinflation, which can decrease fuel efficiency, lead to uneven tire tread wear and reduce tire life, compromise tire safety and cause tire blowout. Check 1999 GMC Sonoma tire pressure regularly, and monitor 1999 GMC Sonoma tire inflation levels to avoid driving with overinflated or underinflated tires.

Tire inflation value listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not the recommended tire pressure for 1999 GMC Sonoma. Use 1999 GMC Sonoma recommended tire pressure settings listed on the tire pressure chart found in 1999 GMC Sonoma owner's manual, on a sticker on driver's door or door jam, inner trunk lid, in the console or on the fuel door. Recommended tire pressure for your 1999 GMC Sonoma tires will be listed in one of the following pressure units: psi (pounds per square inch), bar or kPa (kiloPascals). Pay attention as your 1999 GMC Sonoma may have different recommended tire pressure values for front and rear tires, especially if equipped with staggered tires. Keep your 1999 GMC Sonoma tires inflated at recommended tire pressure levels at all times for your driving comfort and safety.

If you replace 1999 GMC Sonoma original equipment tires or switch to plus size tires, make sure to follow guidelines for the application of load and inflation tables to find proper tire pressure for your new 1999 GMC Sonoma tires. 1999 GMC Sonoma tires with the same load index, regardless of tire size, may carry the same load, but may require substantially different inflation pressures. Tire load index may not be used independently to determine replacement tire acceptability for load capacity. An equal or greater load index does not always correspond to equal or greater load capacity at all inflation pressure settings.

Always refer to the 1999 GMC Sonoma owner’s manual for any specific safety advice regarding the application of 1999 GMC Sonoma replacement tires.
