10-46 Vehicle Care

All-Season Tires

This vehicle may come with
all-season tires. These tires are
designed to provide good overall
performance on most road surfaces
and weather conditions. Original
equipment GM all-season tires
can be identified by the last two
characters of the TPC code, which
will be MS. See Tire Sidewall
Labeling on page 10 47.
Consider installing winter tires on
the vehicle if frequent driving on
snow or ice covered roads is
expected. All-season tires provide
adequate performance for most
winter driving conditions, but they
may not offer the same level of
traction or performance as winter
tires on snow or ice covered roads.
See Winter Tires on page 10 46.

Winter Tires

Consider installing winter tires on
the vehicle if frequent driving on
snow or ice covered roads is
expected. All season tires provide
good overall performance on most
surfaces, but they may not offer
the traction 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 changing to winter
tires, be alert for changes in vehicle
handling and braking.
See your dealer for details
regarding winter tire availability and
proper tire selection. Also, see
Buying New Tires on page 10 62.
If using snow 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 the original equipment tires
may not be available for H, V, W, Y,
and ZR speed rated tires. If winter
tires with a lower speed rating are
chosen, never exceed the tire's
maximum speed capability.
