Diagnostic Procedure # 3 - Tires

1. Verify that the tire size on the vehicle is that listed on the vehicle certification label. Set tire inflation pressures to those specified on the certification.

2. Spin the front tires to be sure that the front hubs are unlocked. If the hubs are unlocked, the axle shaft will not rotate with the wheels (4x4 models only).

3. Measure tire circumference of all four tires; put the two closest circumference tires on the rear axle. Tire pressure must be equal on all tires.
