* Important Consumer Information When Considering New Tires or Wheels for GM Vehicles
Using different size wheels or tires
If you add wheels or tires that are a different size than your original
equipment wheels and tires, this may affect the way your vehicle
performs, including its braking, ride and handling characteristics,
stability, [and] resistance to roll-over, tire tread wear rate, fuel
economy and tire traction (on wet, dry, snow covered and icy roads).
Additionally, if your vehicle has electronic systems such as, anti-lock
brakes, traction control, and electronic stability control, the
performance of these systems can be affected. These changes in vehicle
performance are not covered by the GM New-Vehicle Limited Warranty.
Replacing Tires
GM has developed and matched specific tires and wheels for each GM
vehicle application. GM strongly recommends that replacement tires be
the same as the original equipment tires. This way, your vehicle will
continue to have tires that are designed to give the same performance
and vehicle safety, during normal use, as the original tires. If you choose different performance characteristics, make sure that replacement tires are the
same size, load range, speed rating, and construction type (radial and
bias-belted tires) as the vehicle's original tires. In addition, GM
recommends replacing tires in sets of four. This is because uniform
tread depth on all tires will help keep your vehicle performing most
like it did when the tires were new. Replacing less than a full set of
tires can affect the braking and handling performance of your vehicle.
