Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and
you could have a crash.
Using
tires of different sizes may also cause
damage to your vehicle. Be sure to
use the same '
size and type tires on all four wheels.
It's all right to drive with your compact spare,
though.
It was developed for use 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.

Traction -- A, B, C
The traction grades, from highest to lowest, are A, B
and C, and they represent the tire’s ability to stop on
wet pavement as measured under controlled conditions
on specified government test surfaces of asphalt
and concrete.
A tire marked C may have poor
traction performance.
Warning: The traction grade assigned
to this tire is based
on braking (straightahead) traction tests and does not
include cornering (turning) traction.
Temperature -- A, B, C
The temperature grades are A (the highest), B and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material
of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure,
The grade
C corresponds to a level of performance which
all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades
A and B represent higher levels of performance on the
laboratory test wheel than the minimum required
by law.
Warning: The temperature grade for this tire is
established for a tire
that is properly inflated and not
overloaded. Excessive speed, underinflation or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to have your wheels
aligned again. However,
if you notice unusual tire wear
or your vehicle pulling
one way or the other, the
alignment may need to
be reset. If you notice your
vehicle vibrating when driving on
a smooth road, your
wheels may need
to be rebalanced.

Whenever possible, schedule an appointment for your
vehicle’s warranty work. Your Cadillac dealer can then
prepare
to meet your alternative transportation needs
and minimize inconveniences typically associated with
warranty repairs.
Owner Responsibilities
There are only two things which you will be responsible for
during the use of your courtesy vehicle.
You are required to
provide
insurance coverage and replenish the fuel used.
In many cases your own auto insurance policy may
provide primary coverage for the courtesy vehicle,
similar
to rental car agreements. Please, check with your
insurance company to be certain what’s covered.
This service is provided to you under the terms of the
New Vehicle
Warranty, therefore, it is imperative that your
vehicle be picked up fiom the dealership at the completion
of
the warranty service. Vehicles not picked up in a timely
fashion may incur rental
fees charged to the customer.
Some state insurance regulations make it impractical to
rent vehicles to people under
21 years of age. If you are
under
21 and have difficulty renting a vehicle, Cadillac
will reimburse
you, up to $30/day, for any documented
transportation you receive.
