Low-Profile Performance Tire
If your vehicle has 215/45R18 size tires, they are
classified as low-profile performance tires. These
tires are designed for very responsive driving on
wet or dry pavement. You may also notice more
road noise with low-profile performance tires and
that they tend to wear faster.
Notice:
If your vehicle has low-profile tires,
they are more susceptible to damage from road
hazards or curb impact than standard profile
tires. Tire and/or wheel assembly damage can
occur when coming into contact with road
hazards like, potholes, or sharp edged objects,
or when sliding into a curb. Your GM warranty
does not cover this type of damage. Keep tires
set to the correct inflation pressure and, when
possible avoid contact with curbs, potholes,
and other road hazards.
Winter Tires
If your vehicle has 215/45R18 size tires, they are
classified as low-profile performance tires. These
tires are designed for very responsive driving on
wet or dry pavement. If you expect to drive on snow
or ice covered roads often, you may want to get
winter tires for your vehicle.
All season tires provide good overall performance
on most surfaces but they may not offer the traction
you would like or the same level of performance as
winter tires on snow or ice covered roads.
Winter tires, in general, are designed for increased
traction on snow and ice covered roads. With winter
tires, there may be decreased dry road traction,
increased road noise, and shorter tire tread life.
After switching to winter tires, be alert for changes
in vehicle handling and braking.
See your dealer for details regarding winter tire
availability and proper tire selection. Also, see
Buying New Tires on page 347
.
If you choose to use winter tires:
•
Use tires of the same brand and tread type on
all four wheel positions.
•
Use only radial ply tires of the same size, load
range, and speed rating as your original
equipment tires.
Winter tires with the same speed rating as your
original equipment tires may not be available for H,
V, W, Y and ZR speed rated tires. If you choose
winter tires with a lower speed rating, never
exceed the tire’s maximum speed capability.
