Wheels and Tires: Testing and Inspection

1. Inspect the tire, as follows:
a. Check the tires for wear and for the proper inflation pressure, the cold tire inflation pressure for vehicles driving under 120 km/h (75 mph) are as follows:

Tire Size: P235/75 R15
Tire Pressure
Front: 180 kPa (26 psi)
Rear: 200 kPa (29 psi)

Tire Size: P265/70 R16
Tire Pressure
Front: 180 kPa (26 psi)
Rear: 200 kPa (29 psi)





b. Check the tire runout.

Tire runout: 3.0 mm (0.118 inch) or less.





2. Rotating Tires.

NOTE: See the illustration to see where to rotate each tire.





3. Inspect the wheel balance, as follows:
a. Check and adjust the off-the-car balance.
b. If necessary, check and adjust the on-the-car balance.

Unbalance after adjustment: 14.0 g (0.031 lbs.) or less.

4. Check the wheel bearing looseness.
5. Check the steering linkage for looseness.
6. Check the ball joint for looseness.
7. Check to see if the shock absorber works properly, checking the following.
- Check for oil leaks.
- Check the mounting bushings for wear.
