All Models, All Years
INTRODUCTION:
The purpose of regularly rotating tires is to achieve more uniform wear for all tires on a vehicle.
Recent changes to the maintenance schedule require the checking of tread depth to determine the need for tire rotation, rather than rotation at a fixed
interval.
The purpose of the procedure outlined below is to assist you in determining whether a customer's tires need to be rotated.
NOTE:
If a customer's tires show uneven wear, check for and correct any misalignment, imbalance or other mechanical problem involved before

rotation.
INSPECTION PROCEDURE:
The first tire rotation is the most important. Below are examples for when you should and should not rotate the tires.
Rotation is needed
Rotation is NOT needed
Procedure:
1. Measure the center tread depth. (See diagram)
2. Compare the front tires center tread depth with the rear tires.
3. If one or both tires have equal or more than (20% or 1 mm) difference between the center of the front and rear tires, rotate the tires.
4. Measure the inner and outer tire shoulder tread depth. (See diagram)
5. Compare the front tires inner and outer tire shoulder tread depth with the rear tires.
6. If one or both tires have equal or more than (20% or 1 mm) difference between the shoulders of the front and rear tires, rotate the tires.
