Since each tire performs different tasks (such as steering or front versus rear wheel drive), tires
wear at different rates. Rotating tires at recommended intervals extends their useful life and achie ves
more uniform wear. Your tires should be rotated between every 6,000 and 8,000 miles, and is included
in both Maintenance I and Maintenance II packages. Just bring it by and we will do it while you wait.
