Replacement Tires — When replaci ng ti res,
only the size, load range, and construction
type (radial) originally installed on your vehi¬
cle are recommended. Use of any other size or
type tire may seriously affect ride, handling,
speedometer/odometer calibration, vehicle
ground clearance and tire clearance to the
body and chassis. The following also should
be considered when replacing tires:
• Because of possible adverse effects on
vehicle handling, do not mix radial ply
tires with other type tires on the same
vehicle (such as bias or bias-belted snow
tires.)
• When replacing only one tire, it should
be paired with the tire having the least
wear, to equalize braking traction.
ance of ride, handling, and traction on
wet, dry and snow covered surfaces. Re¬
placing your tires with tires having the
identical TPC Spec. No. will assure you
of a tire designed to the same dimen¬
sional and performance specifications.
Snow Tires — Your steel-belted radial tires
were designed to provide better traction per¬
formance in snow than conventional con¬
struction type tires without snow treads. How¬
ever, ifyou equipyour vehicle with snowtires,
use ONLY RADIAL SNOW TIRES. Snow tires
should be inflated 4 psi above the recom¬
mended pressures shown on the tire placard
up to a maximum of 32 psi (cold) for load
range B tires, and 40 psi for load range D tires.
It is recommended that vehicle speeds be li¬
mited to a maximum of 75 mph if snow tires
are installed.
Replacement Wheels — Wheels must be
replaced if they become bent, are heavily
rusted, if the lug nuts won't stay tight, or if
they leak air. Straightening bent wheels or
using inner tubes in leaking wheels are not
recommended repair procedures.
When replacing wheels for any reason,
care should be taken to insure that the
wheels are equivalent to those removed in
load capacity, diameter, rim width, and off¬
set. Correct replacement wheels can be ob¬
tained from your Cadillac dealer.
Use of any other size or type wheel may
adversely affect wheel and wheel bearing
life, brake cooling and stopping ability,
headlamp aim, speedometer-odometer ac¬
curacy, bumper height, vehicle ground
clearance and tire clearance to the body
and chassis.
The use of used wheels is also not re¬
commended; if they have been run over¬
loaded or under other severe operating
conditions for extended periods, the wheel's
life may have been greatly shortened.
Warranty —Tires are warranted by the tire
manufacturers as covered in the Tire Owner's
Guide and Guarantee booklet furnished with
your vehicle. However, for the added con¬
venience of owners, many Cadillac dealers
are equipped to handle tire warranty adjust¬
ments on certain makes of tires provided on
1975 Cadillac cars.
• Steel-belted radial tires have a TPC Spec.
No. (Tire Performance Criteria Specifica¬
tion Number) molded on the sidewalls
near the tire size marking. This designa¬
tion indicates that the tire meets rigid di¬
mensional and performance standards
which were developed for your Cadillac.
These specifications insure a proper bal¬
