Here are some tips for winter driving:
Have your vehicle in good shape for winter. Include
an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing,
a small shovel, a flashlight, a red cloth and
reflective warning triangles. And,
if you will be driving
under severe conditions, include a small bag
of sand, a
piece of old carpet or a couple of burlap bags
to help
provide traction. Be sure you properly secure these
items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However, if there
is snow or ice between your tires and
the road,
you can have a very slippery situation. You’ll
have a
lot less traction or “grip” and will need to be
very careful.
0 You may want to put winter emergency supplies in
your vehicle.

If you use bias-ply tires on your vehicle, the
wheel rim flanges could develop cracks after
many miles of driving.
A tire and/or wheel could
fail suddenly, causing a crash. Use only radial-ply
tires with the wheels on your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance.
(This applies only to vehicles sold in the United
States.) The grades are molded on the sidewalls of
most passenger car tires. The Uniform Tire Quality
Grading system does not apply
to deep tread,
winter-type snow tires, space-saver or temporary
use spare tires, tires with nominal rim diameters
of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires. While
the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform
to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate
of the tire when tested under controlled
conditions
on a specified government test course. For
example, a
tire graded 150 would wear one and a
half
(1 1/2) times as well on the government course
as
a tire graded 100. The relative performance of tires
depends upon
the actual conditions of their use,
however, and may depart significantly from the norm
due to variations in driving habits, service practices
and differences in road characteristics and climate.
