Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found on the rear edge of the driver's door tells you the
proper size, speed rating and recommended inflation
pressures for the tires on your vehicle. It also gives you
important information about the number of people that can be in your vehicle and the total weight that you can
carry. This weight is called the Vehicle Capacity Weight
and includes the weight
of all occupants, cargo, and all
nonfactory-installed options.

The other label is the Certification label, found on the
rear edge of the driver’s door. It tells you the
gross
weight capacity of your vehicle, called the GVWR (Gross
Vehicle Weight Rating). The
GVWR includes the weight
of the vehicle, all occupants, fuel and cargo. Never
exceed the GVWR for your vehicle, or the Gross Axle

(GAWR) for either the front or rear axle.

Tires
We don't make tires. Your new vehicle comes-with high
quality tires made by a leading tire manufacturer. These
tires are warranted by the tire manufacturers and their warranties are delivered with every new Buick.
If your
spare tire is a different brand than your road tires, you
will have
a tire warranty folder from each of these
manufacturers.

Inflation - Tire Pressure
The Tire-Loading Information label which is located on
the rear edge
of the drivers door shows the correct
inflation pressures
for your tires, when they’re cold.
“Cold” means your vehicle has been sitting for at least
three hours or driven no more than a mile.
245

When to Check: Check your tires once a month or
more.
Don’t forget your compact spare tire. It should be at
60
psi (420 kPa).
I
How to Check: Use a good quality pocket-type gage to
check tire pressure. Simply looking at the tires will not
tell you the pressure, especially
if you have radial tires --
which may look properly inflated even if they’re
underinflated.
If your tires have valve caps, be sure to put them back on. They help prevent leaks .by keeping out dirt and
moisture.
Tire Inspection and Rotation
To make your tires last longer, have them inspected and
rotated at the mileages recommended
in the
Maintenance, Schedule. See “Scheduled Maintenance
Services”
in the Index.
r-
Use this rotation pattern.
After the tires have been rotated, adjust the front and
rear inflation pressure
as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque”
in the
Index.

A CAUTION:

Buying New .Tires
To find out what kind and size of tires you need, look at
:the Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
:get ones with that same TPC Spec number. That way,
*your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by a
“MS’,
(for mud and snow).
;If you ever replace your tires with those not having a
!.TPC Spec number, make sure they are the same size,
load rdnge, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
, A CAUTION:
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
1 vehicle may not handle properly, and you cou’ ’
have a crash. Be sure to use the same size ana
type tires on all four wheels.
It’s
all right to drive with your compact spa
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.)
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
