Chevrolet 2011 Express 1500 Cargo Owner's Manual page 340

GM recommends replacing all the
tires at the same time. Uniform tread
depth on all tires will help to
maintain the performance of the
vehicle. Braking and handling
performance may be adversely
affected if all the tires are not
replaced at the same time. See
information on proper tire rotation.
Tires could explode during
improper service. Attempting to
mount or dismount a tire could
cause injury or death. Only your
dealer or authorized tire service
center should mount or dismount
the tires.
Mixing tires of different sizes,
brands, or types may cause loss
of control of the vehicle, resulting
in a crash or other vehicle
damage. Use the correct size,
brand, and type of tires on
and
all wheels.
for
This vehicle may have a different
size spare than the road tires
originally installed on the vehicle.
When new, the vehicle included a
spare tire and wheel assembly
with a similar overall diameter as
the road tires and wheels, so it is
all right to drive on it.
The spare tire was developed for
use on this vehicle and will not
affect vehicle handling.
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
A tire and/or wheel could fail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
