Subject:
Improper Tire Pressure
Models:
1999-2OOO Passenger Cars and Trucks
Important:
Tires must be set to the recommended inflation pressure during the pre-delivery inspection (including the spare tire).
Ride, handling and road noise concerns may be caused by improperly adjusted tire pressure. The first step in diagnosis of these concerns is to verify that the tires are inflated to the correct pressures. The recommended tire inflation pressure is listed on the vehicle's tire placard. The tire placard is located on the driver's door edge or the rear compartment lid. Do not use the tire pressure indicated on the tire itself as a guide. Always inspect and adjust the pressure when the tires are cold. Vehicles that have different pressures for the front and the rear need to be adjusted after tire rotation.
Improper tire inflation may result in any or all of the following conditions:
^ Premature tire wear
^ Harsh ride
^ Excessive road noise
^ Poor handling
^ Reduced fuel economy
