Low-Profile Tires; Summer Tires; Tire Sidewall Labeling - Cadillac CT4 2023 Owner's Manual

324 Vehicle Care
Caution
Do not drive on a deflated self-sealing
tire as this could damage the tire. Make
sure the tire is inflated to the
recommended pressure or have it
immediately repaired or replaced.
When tire replacement is needed replace
with a self-sealing tire, because the vehicle
does not come with a spare tire or tire
changing equipment.

Low-Profile Tires

If the vehicle has 225/45R17 91V,
235/40R18 91V, 235/40R18 XL 95Y,
or 235/35R19 XL 91V, 255/35ZR18 (94Y),
or 275/35ZR18 (99Y) size tires, they are
classified as low-profile tires.
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
Caution (Continued)
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 0 322.
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 0 334.

Tire Sidewall Labeling

Useful information about a tire is
molded into its sidewall. The example
