In order to equalize wear, rotate the tire and the wheel assemblies at the specified intervals. Refer to Maintenance Schedule - Short Trip/City or Maintenance Schedule - Long Trip/Highway in Maintenance and Lubrication. In addition to scheduled rotation, the tire and wheel assemblies should also be rotated whenever uneven tire wear is noticed.

Due to the tire design, radial tires tend to wear faster in the shoulder area, particularly in front positions (1, 2). Radial tires in non-drive locations may develop an irregular wear pattern that can increase tire noise if not rotated. This makes regular rotation especially necessary.

After rotation, be sure to check the wheel nuts for fastener tightening specification and adjust the inflation pressure.
