Properly inflated tires provide the best combination of handling, tread life, and comfort. The air pressure inside the tires supports the weight of the vehicle. Tire pressure is the inflation pressure specification, measured in Pounds per Square Inch (PSI), for a given tire type, size, and application.
The cold tire inflation pressure, PSI, is on the Tire Information Label located on the driver’s side door jamb.
Because tires can lose 1 to 2 PSI of tire pressure per month, tire pressures must be checked regularly.
