Wheels: Description and Operation

Replacement Wheels Description

Caution: Do Not use flat mount wheels on dual ring type wheel applications. The use of flat mount wheels on a dual ring application may cause the wheel to loosen and could cause loss of vehicle control resulting in personal injury.


Replace the wheel if any of the following conditions exist:

* The wheel exhibits excessive runout.
* The wheel is bent.
* The wheel is cracked.
* The wheel is severely corroded.

Important: Air leaks caused by porosity on aluminum wheels are repairable.


* The wheel leaks air.
Caution: If you are replacing the wheel(s), the wheel stud(s), the wheel nut(s) or the wheel bolt(s), install only new GM original equipment parts. Installation of used parts or non-GM original equipment parts may cause the wheel to loosen, loss of tire air pressure, poor vehicle handling and loss of vehicle control resulting in personal injury.




Notice: The use of non-GM original equipment wheels may cause:

* Damage to the wheel bearing, the wheel fasteners and the wheel
* Tire damage caused by the modified clearance to the adjacent vehicle components
* Adverse vehicle steering stability caused by the modified scrub radius
* Damage to the vehicle caused by the modified ground clearance
* Speedometer and odometer inaccuracy



Replace the wheel, the wheel studs and the wheel/nuts, or the wheel bolts if applicable, if any of the following conditions exist:

* The wheel has elongated bolt holes.
* The wheel/nuts, or bolts if applicable, loosen repeatedly.


Aluminum wheel identification is cast into the inboard side of the wheel.
