The pressure recommended for any vehicle line is carefully calculated to give
a satisfactory ride, handling, tread life, and load-carrying capacity.
Tire pressure should be checked monthly or before any extended trip. Inspect
the tires when they are cold, after the vehicle has sat for 3 hours or more,
or has been driven less than 1 mile. Set the tire pressure to the specifications
on the tire label located on the rear face of the driver's door. Tire inflation pressure

Tire and Wheel Specifications
