Tire Rotation The tires on your vehicle are different sizes front to rear. Due to this, your tires should not be rotated. Each tire and wheel should be used only in the position it is in. You need a new tire if any of the following statements are true: • You can see the indicators at three or more places around the tire. • You can see cord or fabric showing through the tire's rubber. When It Is Time for New Tires One way to tell when it is time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining. • The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric. • The tire has a bump, bulge or split. • The tire has a puncture, cut or other damage that cannot be repaired well because of the size or location of the damage. 5-69
