Tyre Chains; If A Tyre Goes Flat - Cadillac CTS Owner's Manual

Used Replacement Wheels
Warning
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.

Tyre Chains

Use tyre chains or other traction
devices only when necessary.
Before using tyre chains, check with
the tyre manufacturer to make sure
tyre chains are compatible with the
tyres on the vehicle. Follow the
manufacturer's instructions.
Tyre chains are only permitted on
P245/40R18 93V size tyres. Install
them on the rear tyres only, as
tightly as possible with the ends
securely fastened.
Only use low profile tyre chains that
are the proper size for the tyres and
add no more than 6 mm thickness
to the tyre tread and inner sidewall.
Caution
Do not install traction devices on
the front tyres.
Drive slowly and follow the cable
manufacturer's instructions. If the
cables are contacting the vehicle,
stop and retighten them. If the
contact continues, slow down until it
stops.
Caution
To help avoid damage to the
vehicle, drive slowly, do not spin
the wheels, and readjust or
remove the device if it contacts
the vehicle.
Vehicle Care

If a Tyre Goes Flat

If the vehicle has run-flat tyres,
there is no need to stop on the side
of the road to change a flat tyre.
See Run-Flat Tyres 0 287.
Warning
Special tools and procedures are
required to service a run-flat tyre.
If these special tools and
procedures are not used, injury or
vehicle damage may occur.
Always be sure the proper tools
and procedures, as described in
the service manual, are used.
It is unusual for a tyre to blow out
while driving, especially if the tyres
are maintained properly. See Tyres
0 286. If air goes out of a tyre, it is
much more likely to leak out slowly.
But if there is ever a blowout, here
are a few tips about what to expect
and what to do:
If a front tyre fails, the flat tyre
creates a drag that pulls the vehicle
toward that side. Take your foot off
