Winter Tires - Chevrolet 2009 Cobalt Owner's Manual

Low-Profile Performance Tire
If the vehicle has 225/40R18 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.
The 225/40R18 tire is a high performance tire
designed for dry traction and handling performance
which may result in reduced tread life of
15,000 miles (24 140 km) or less depending on
individual driving behavior.
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.

Winter Tires

If the vehicle has 225/40R18 size tires, they are
classified as 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 the 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 5-72.
