Chevrolet Silverado: Wheels and Tires / Different Size Tires and Wheels
If wheels or tires are installed that are a different size than the original
equipment wheels and tires, vehicle performance, including its braking, ride and
handling characteristics, stability, and resistance to rollover may be affected.
If the vehicle has electronic systems such as antilock brakes, rollover airbags,
traction control, electronic stability control, or All-Wheel Drive, the performance
of these systems can also be affected.
Warning
If different sized wheels are used, there may not be an acceptable level
of performance and safety if tires not recommended for those wheels are selected.
This increases the chance of a crash and serious injury. Only use GM specific wheel
and tire systems developed for the vehicle, and have them properly installed by
a GM certified technician.
See Buying New Tires and Accessories and Modifications.
GM has developed and matched specific tires for the vehicle. The original equipment
tires installed were designed to meet General Motors Tire Performance Criteria Specification
(TPC Spec) system rating...
The following information relates to the system developed by the United States
National Highway Traffic Safety Administration (NHTSA), which grades tires by treadwear,
traction, and temperature performance...
Other information:
Vehicles with StabiliTrak/Electronic Stability Control (ESC) have a Trailer Sway
Control (TSC) feature. Trailer sway is unintended side-to-side motion of a trailer
while towing. If the vehicle is towing a trailer and the TSC detects that sway is
increasing, the vehicle brakes are selectively applied at each wheel, to help reduce
excessive trailer sway...
Warning
To prevent serious injury or death, always park your vehicle and trailer
on a level surface when possible.
When parking your vehicle and your trailer on a hill:
Press the brake pedal, but do not shift into P (Park) yet. Turn the wheels
into the curb if facing downhill or into traffic if facing uphill...
