Winter Tires; Tire Sidewall Labeling - Chevrolet 2011 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 63.
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.
