Winter Tires; Tire Sidewall Labeling - Pontiac 2007 G6 Owner's Manual

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 383.

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.
