Pontiac 2008 G6 - Manual (Page 297)

Low-Profile Performance Tire
If your vehicle has P225/50R18 or P225/50R17 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
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 your vehicle has P225/50R18 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.
The low-profile performance tires 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 retailer for details regarding winter tire
availability and proper tire selection. Also, see Buying
New Tires on page 5-79.
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
and ZR speed rated tires. If you choose winter tires with
a lower speed rating, never exceed the tire’s maximum
speed capability.
