WARNING:
A leaking wheel could fail without warning.
A wheel designed for tubeless tires could be
leaking because it is damaged. Do not use an
inner tube or some other thing to try to stop the
leaking. Get a new wheel of the proper type.
Using wheels and tires with higher load-carrying limits
than the original wheels and tires does not change the
Gross Axle Weight Rating (GAWR) or the Gross Vehicle
Weight Rating (GVWR) of your vehicle. See Loading
the Vehicle on page 4 18 for more information.
Notice: The wrong wheel can cause trouble in
bearing life, brake cooling, speedometer/odometer
calibration, headlamp aim, bumper height, vehicle
ground clearance, stopping distance and tire
clearance to the body and chassis. You could also
have other problems like a tire air-out.
Used Replacement Wheels
WARNING:
Putting a used wheel on the vehicle is dangerous.
You cannot know how it has been used or how far
it has been driven. It could fail suddenly and
cause a crash. If you have to replace a wheel, use
a new GM original equipment wheel.
