Tire Replacement, Traction and Maintenance
Wheel Replacement
When replacing metal wheels for any reason, make sure the new wheels are equivalent to the original factory wheels in diameter, rim width, and offset.
Tire Traction
Tire traction may be reduced if you drive on worn tires, improperly inflated tires, or slippery road surfaces. Tires must be replaced when the tread wear indicators appear. To reduce the possibility of losing control, slow down whenever the road is wet, snowy, or icy.
Tire Maintenance
In addition to proper inflation, proper wheel alignment helps reduce tire wear. If you find that a tire is worn unevenly, contact your dealer to have the wheel alignment checked.
When new tires are installed, make sure they are balanced. This will improve ride comfort and tire life. In addition, the tire must always be rebalanced if it has been removed from the wheel.
