LowProfile Performance Tires
If your vehicle has 255/45ZR18 size tires, they
are classified as lowprofile performance tires.
These tires are designed for very responsive
driving on wet or dry pavement. You may also
notice more road noise with lowprofile
performance tires and that they tend to wear
faster. These performance tires are not rated as
allseason tires. Winter tires are recommended for
snow or ice covered roads.
Notice: If the vehicle has lowprofile 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.
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 670.
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.
