Chevrolet EXPRESS - 2011 Manual page 341

This vehicle may have a different
size spare than the road tires
(those originally installed on the
vehicle). When new, the vehicle
included a spare tire and wheel
assembly with a similar overall
diameter as the vehicle's road
tires and wheels, so it is all right
to drive on it. Because this spare
was developed for use on
the vehicle, it will not affect
vehicle handling.
If you use bias-ply tires on the
vehicle, the wheel rim flanges
could develop cracks after
many miles of driving.
(Continued)
A tire and/or wheel could fail
suddenly, causing a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If you must replace the vehicle's
tires with those that do not have a
TPC Spec number, make sure they
are the same size, load range,
speed rating, and construction type
(radial and bias belted tires) as the
vehicle's original tires.
Vehicles that have a tire pressure
monitoring system may give an
inaccurate low pressure warning
if non TPC Spec-rated tires
are installed on the vehicle.
Non TPC Spec-rated tires may
give a low pressure warning that
is higher or lower than the proper
warning level you would get with
TPC Spec-rated tires. See
.
The vehicle's original equipment
tires are listed on the Tire and
Loading Information label. See
for more information about the Tire
and Loading Information label and
its location on the vehicle.
If you add wheels or tires that
are a different size than the original
equipment wheels and tires, this
could affect the way the vehicle
performs, including its braking,
ride and handling characteristics,
stability, and resistance to rollover.
Additionally, if the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
