Low-Profile Performance Tires
If your vehicle has 235/50ZR18, P235/50R18,
255/40ZR19 or 285/35ZR19 size tires, they are
classified as low-profile 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 the 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. The vehicle
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.
Summer Performance Tires
Many General Motors high performance models
come factory-equipped with tires that are optimized
for maximum dry and wet road performance while
still retaining satisfactory tread life, excellent
durability, and low noise levels. In severe winter
climates where snowfall may be significant, these
tires may be found to provide less traction.
Winter Tires
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 tread life. After switching to winter
tires, be alert for changes in vehicle handling and braking.
See your dealer/retailer for details regarding winter tire
availability and proper tire selection. Also, see Buying
New Tires on page 5-82.
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 the 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.
