Winter Tires; Tire Sidewall Labeling - Chevrolet 2012 Volt Owner's Manual

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 59.
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.

Tire Sidewall Labeling

Useful information about a tire is
molded into its sidewall. The
