BASIC TIRE MAINTENANCE
Properly maintained tires improve the steering, stopping, traction and load carrying capability of your vehicle. Under inflated tires and overloaded vehicles are a major cause of tire failure. To avoid flat tires and other types of failure, you should maintain proper tire pressure, observe tire and vehicle load limits, avoid road hazards and regularly inspect ALL of your tires.
Tire information placards and vehicle certification labels contain information on tires and load limits. The labels indicate the vehicle manufacturer's information including:
- Recommended tire size
- Recommended tire inflation pressure
- Vehicle capacity weight (VCW)
- Front and rear gross axle weight ratings (GAWR)
Both placards and certification labels are permanently attached to the vehicle door edge, door post, glove box door or inside the trunk lid and of course in the owners manual for your vehicle.
Rotating tires from front to back and from side to side can reduce irregular wear. Look in your owner's manual for information on how frequently the tires on your vehicle should be rotated and the best pattern for rotation.
For maximum mileage, rotate your tires every 5,000 miles and follow the correct rotation patterns
To Maintain tire safety, purchase new tires that are the same size as the vehicle's original tires or another size recommended by the manufacturer. Look at the tire information placard, the owners manual or the sidewall of he tire you are replacing to find this information.
