Low-Profile Tyres - Cadillac CTS Owner's Manual

288 Vehicle Care
Warning (Continued)
displayed. Drive cautiously and
check the tyre pressures as soon
as possible.
Run-flat tyres can be driven on with
no air pressure. There is no need to
stop on the side of the road to
change the tyre. Continue driving;
however, do not drive too far or too
fast. Driving on the tyre may not be
possible if there is permanent
damage. To prevent permanent
damage, keep speed below 80 km/h
(50 mph). With a light load the
vehicle can be driven up to 100 km
(60 mi); with a moderate load 80 km
(50 mi); and a heavy load 45 km
(25 mi). As soon as possible,
contact the nearest authorised GM
or run-flat servicing facility for
inspection and repair or
replacement.
When driving on a deflated run-flat
tyre, avoid potholes and other road
hazards that could damage the tyre
and/or wheel beyond repair. When a
tyre has been damaged, or driven
any distance while deflated, check
with an authorised run-flat tyre
service centre to determine whether
the tyre can be repaired or should
be replaced. To maintain the run-flat
feature, all replacement tyres must
be run-flat tyres.
To locate the nearest GM or run-flat
servicing facility, call Customer
Assistance.
The valve stems on run-flat tyres
have sensors that are part of the
TPMS. See Tyre Pressure Monitor
System 0 291. These sensors
contain batteries that are designed
to last for 10 years under normal
driving conditions. See your dealer
for wheel or sensor replacement.
Caution
Using liquid sealants can damage
the tyre valves and tyre pressure
monitor sensors in the run-flat
tyres. This damage is not covered
by the vehicle warranty. Do not
use liquid sealants in run-flat
tyres.

Low-Profile Tyres

If the vehicle has 265/35ZR19 or
295/30ZR19 size tyres, they are
classified as low-profile tyres.
Caution
Low-profile tyres are more
susceptible to damage from road
hazards or curb impact than
standard profile tyres. Tyre 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 kerb. The warranty
does not cover this type of
damage. Keep tyres set to the
correct inflation pressure and
when possible, avoid contact with
kerbs, potholes, and other road
hazards.
