Cadillac CT4 Owner Manual (GMNA-Localizing-MidEast-15283644) - 2022 -
CRC - 7/28/21
Caution
Low-profile tires are more
susceptible to damage from road
hazards or curb impact than
standard profile tires. Tire and/or
wheel assembly damage can occur
when coming into contact with
road hazards like potholes, or sharp
edged objects, or when sliding into
a curb. The warranty does not cover
this type of damage. Keep tires set
to the correct inflation pressure and
when possible, avoid contact with
curbs, potholes, and other road
hazards.

Summer Tires

High Performance Summer Tires
This vehicle may come with 235/
40R18 XL 95Y, 255/35ZR18 (94Y),
or 275/35ZR18 (99Y) high
performance summer tires. These tires
have a special tread and compound
that are optimized for maximum dry
and wet road performance. This
special tread and compound will have
decreased performance in cold
climates, and on ice and snow. It is
recommended that winter tires be
installed on the vehicle if frequent
driving at temperatures below
approximately 5 °C (40 °F) or on ice or
snow covered roads is expected. See
Winter Tires 0 321.
Caution
High performance summer tires
have rubber compounds that lose
flexibility and may develop surface
cracks in the tread area at
temperatures below 7 °C (20 °F).
Always store high performance
summer tires indoors and at
temperatures above 7 °C (20 °F)
when not in use. If the tires have
been subjected to 7 °C (20 °F) or
less, let them warm up in a heated
space to at least 5 °C (40 °F) for
24 hours or more before being
installed or driving a vehicle on
which they are installed. Do not
apply heat or blow heated air
directly on the tires. Always inspect
tires before use. See Tire Inspection
0 329.
VEHICLE CARE

Tire Pressure

Tires need the correct amount of
air pressure to operate effectively.
Warning
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires that
do not have enough air, can
result in:
Tire overloading and
overheating, which could lead
to a blowout.
Premature or irregular wear.
Poor handling.
Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can result in:
Unusual wear.
Poor handling.
Rough ride.
Needless damage from road
hazards.
