Rotate the tires at intervals specified in Maintenance and Lubrication in order to equalize wear. In addition to scheduled rotation, rotate the tires whenever wear is found. Radial tires tend to wear faster in the shoulder area, particularly when mounted in front positions (1,2). Radial tires in the non-drive positions (3,4) may develop an irregular wear pattern that can increase tire noise if not rotated. This tendency makes regular rotation especially important.

After rotation, ensure that the wheel nuts are tightened to the specified torque. Adjust the tire pressure.
