until corners clear each other, but do not rotate
it more than 45° from straight down.
Each tie rod should be checked after adjustment
by grasping the center of the tie rod and moving
it up and down. The movement should be equal
in both directions; if not, it is an indication that
the pivot studs are not properly positioned. If
tie rods are not properly positioned, a binding
condition may occur, resulting in poor return of
wheels to straight ahead position. Also check
steering linkage joints for looseness. Replace
inner or outer tie rod pivot if loose.
Make certain that steering wheel is centered
after toe-in adjustment has been made. If nec-
essary, readjust toe-in to center steering wheel.
4. Wheels and Tires
a. Wheels
The wheels on all series cars are 15 inches in
diameter with 6 inch rims. They are constructed of
welded steel and have " L " flange type rims.
All wheels have a raised portion just inside the
point where the outboard bead of the tire contacts
the wheel rim. This raised portion helps keep
the tire on the wheel if a blow-out occurs, or
during extremely severe cornering conditions.
The wheel boll: circle diameter is 5 inches with a
hub bore diameter of 3.0685 inches, maximum. Five
1/2 inch diameter studs are used to mount the
wheel. All wheel mounting studs have right hand
threads. The spider section of the wheel is r e -
versed to accommodate deep formed wheel discs,,
Wheels used on Seventy-Five series cars and
commercial chassis are the same as those used
on 60 and 62 series cars except that they are
riveted together and are of heavier stock thick-
ness. They are painted light gray with a daub of
black paint around the small mounting hole on the
spider section of the wheel. Wheels on 60 and 62
series cars are painted all gray.
b. Tires
Black side wall tires are provided as standard
equipment on all 1963 cars except the 6367
Eldorado Convertible. White side wall tires are
standard on this body style and optional on all
other 1963 body styles.
c. Tire Pressures
Tire pressure should be checked with tires
cold. The car should be standing for three hours
(out of sun) before checking tire pressure, as it
takes this long for temperature of air inside tire
to equalize with outside temperature.
Recommended tire pressures and ply ratings
for the various size tires used on 1963 Cadillac
cars are listed on the following chart.
