Run-Flat Tires (CTS-V)
If your vehicle has run-at tires, there is no spare tire
and no tire changing equipment. Run-at tires perform
so well without any air that a Tire Pressure Monitor
(TPM) is used to alert you if a tire has lost pressure.
SeeTire Pressure Monitor System (CTS-V) on
page 5-70.
{CAUTION:
When the low tire warning light is displayed on
the instrument panel cluster, your vehicle’s
handling capabilities will be reduced during
severe maneuvers. If you drive too fast, you
could lose control of your vehicle. You or
others could be injured. Don’t drive over
55 mph (90 km/h) when the low tire warning
light is displayed. Drive cautiously and check
your tire pressures as soon as you can.If a tire goes at, you won’t need to stop on the side of
the road to change the tire. You can just keep on
driving. The tire can operate effectively with no air
pressure for up to 65 miles (105 km) at speeds up to
55 mph (90 km/h). The shorter the distance you
drive and the slower the speed, the greater the chance
that the tire will not have to be replaced. When a tire
is lled with air, it provides a cushion between the road
and the wheel. Because you won’t have this cushion
when driving on a deated run-at tire, try to avoid
potholes that could damage your wheel and require
replacement of it.
Some road hazards can damage a tire beyond repair.
This damage could occur even before you’ve driven
on the tire in a deated condition. When a tire has been
damaged, or if you’ve driven any distance on a
run-at tire, check with an authorized run-at tire service
center to determine whether the tire can be repaired
or should be replaced. To maintain your vehicle’s run-at
feature, all replacement tires must be self-supporting
tires. As soon as possible, contact the nearest
authorized GM or run-at servicing facility for inspection
and repair or replacement. To locate the nearest GM
or run-at servicing facility, call Roadside Service.
SeeRoadside Service on page 7-6for details.

Run-Flat Tires (CTS-V)
If your vehicle has run-at tires, there is no spare tire
and no tire changing equipment. Run-at tires can
operate effectively with no air pressure for a limited
distance and speed. These tires perform so well without
any air pressure that a Tire Pressure Monitor (TPM)
is used to alert you when there is a low tire condition.
{CAUTION:
When the low tire warning light is displayed on
the instrument panel cluster, your vehicle’s
handling capabilities will be reduced during
severe maneuvers. If you drive too fast, you
could lose control of your vehicle. You or
others could be injured. Don’t drive over
55 mph (90 km/h) when the low tire warning
light is displayed. Drive cautiously and check
your tire pressures as soon as you can.SeeRun-Flat Tires (CTS-V) on page 5-66andTire
Pressure Monitor System (CTS-V) on page 5-70,
for additional information.
{CAUTION:
Special tools and procedures are required to
service a run-at tire. If these special tools and
procedures aren’t used you or others could be
injured and your vehicle could be damaged.
Always be sure the proper tools and
procedures, as described in the service
manual, are used.
To order a service manual seeService Publications
Ordering Information on page 7-11.
