226 Vehicle Care
{Warning
Using the wrong replacement wheels,
wheel bolts, or wheel nuts can be
dangerous. It could affect the braking and
handling of the vehicle. Tires can lose air,
and cause loss of control, causing a crash.
Always use the correct wheel, wheel
bolts, and wheel nuts for replacement.
Caution
The wrong wheel can also cause
problems with bearing life, brake cooling,
speedometer or odometer calibration,
headlamp aim, bumper height, vehicle
ground clearance, and tire or tire chain
clearance to the body and chassis.
Used Replacement Wheels
{Warning
Replacing a wheel with a used one is
dangerous. How it has been used or how
far it has been driven may be unknown.
It could fail suddenly and cause a crash.
When replacing wheels, use a new GM
original equipment wheel.
Tire Chains
{Warning
Tire chains or other traction devices used
on a vehicle without the proper amount
of clearance can cause damage to the
brakes, suspension, or other vehicle parts.
Use tire chains or traction devices only if
the equipment manufacturer recommends
them for the vehicle tire size combination
and road conditions. Follow the
equipment manfacturer’s instructions. The
area damaged by the tire chains could
cause you to lose control of the vehicle
and you or others may be injured in a
crash. To help avoid damage to the
vehicle, drive slowly, readjust, or remove
the device if it is contacting the vehicle.
Do not spin the vehicle's tires.
Caution
Use tire chains only where legal and only
when necessary. Use chains that are the
proper size for the tires. Install them on
the tires of the rear axle. Do not use
chains on the tires of the front axle.
(Continued)
Caution (Continued)
Tighten them as tightly as possible with
the ends securely fastened. Drive slowly
and follow the chain manufacturer's
instructions. If the chains contact the
vehicle, stop and retighten them. If the
contact continues, slow down until it
stops. Driving too fast or spinning the
wheels with chains on will damage the
vehicle.
For Cutaway models with LT245/75R16 or
LT225/75R16 size single or dual rear tires, use
Low Profile Z-Chain or SAE Class S cables.
For Cargo or Passenger models with LT225/
75R16 or LT245/75R16 size tires, use Low
Profile Z-Chain cables. SAE Class S chains are
not recommended.
If the vehicle has dual rear tires, do not use
individual tire chains. Use tire chains that fit
across both dual tires.
If a Tire Goes Flat
It is unusual for a tire to blow out while
driving, especially if the tires are maintained
properly. See Tires0211. If air goes out of a
tire, it is much more likely to leak out
