Tire Inspection and 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. Check your tires and wheels regularly for unusual wear and damage. Also see, Scheduled Maintenance on page 6-4, When It Is Time for New Tires on page 5-72 and Wheel Replacement on page 5-75. 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. • The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric. When It Is Time for New Tires One way to tell when it's 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. Some commercial truck tires may not have treadwear indicators. • The tire has a bump, bulge or split. • The tire has a puncture, cut or other damage that can't be repaired well because of the size or location of the damage. 5-72
