1972 Cadillac - GM Heritage Center

TIRES
STANDARD
Blackwall Fiberglass Belted tires, size L78-15,
load range B, are standard on all cars except "75"
Sedan and Limousine. On "75" cars, the L78-15,
load range D tire is standard.
OPTIONAL
Whitewall tires of the same size are optional. Two
white (one broad outside and one narrow inside)
bands accent the sidewall. This whitewall treatment
lends itself to the formal appearance of the 1972
Cadillac. Order basic group 1 through 4 or specify
code W.
To specify a tire brand, use the following codes:
U - Uniroyal G - Goodrich
F - Firestone Y - Goodyear
E - General
FIBERGLASS BELTED TIRES
The construction and configuration of this tire
are designed to increase tread wear, improve handling
characteristics and make the tire more resistant
to road hazards.
This tire is made with two plies of polyester cord
body and two fiberglass belts. The two plies of polyester
cord and the fiberglass belts are applied on the
bias.
ALL TIRE BRANDS NOT ALWAYS AVAILABLE
Tires for Cadillac cars are supplied by five manufacturers in a variety of sizes, and black
or white side walls. This complexity creates storage problems that make a continual inventory
of all makes and types difficult to maintain.
Also, availability problems are encountered since all tires must meet the standards of
Cadillac's quality control program. It is realized that some customers designate a tire brand
preference which dealers understandably wish to accommodate. However, as a relatively small
percentage of such requests can be considered without risking a delay in car production, only
in case of customer insistence should tire brands be specified on the car order.
Notwithstanding these situations, Cadillac will endeavor to supply a tire brand option,
provided such requests do not exceed 5% of a dealer's orders during a model year.
Black side wall tires are standard equipment on all cars. Because of the extremely small
demand, it is not feasible to offer a black wall tire brand option even on a limited basis.
TRACK MASTER
Track Master—Code X-a computer controlled
rear wheel braking system is available on all styles.
The primary purpose of this device is to sense any
impending lockup of the rear wheels and automatically
"pump" the brakes; thereby enabling the
average driver to maintain vehicle control while
stopping in the shorter distances usually obtainable
only by skilled drivers. This system partially releases
the rear brakes as they approach the skid point and
then automatically reapplies them. This process
repeats with the brakes being alternately applied
and released as long as the impending skid situation
prevails.
The system's major components are: a pair of
electric sensors on the rear axle to monitor rear
wheel speed; an electronic computer under the instrument
panel that determines rear optimum wheel
braking performance; and a modulator on the cowl
in the engine compartment that controls the rear
brake pressure to prevent skids.
