In order to equalize wear, rotate the tires at the specified intervals. In addition to scheduled rotation, rotate the tire and wheel assembly whenever you notice uneven tire wear. Refer to Maintenance Schedule in Maintenance and Lubrication.
Radial tires tend to wear faster in the shoulder area, particularly in front positions, due to design. Radial tires in non-drive locations may develop an irregular wear pattern that can generate tire noise. This especially makes regular tire rotation necessary.
