Run-Flat Tires (CTS-V)
If your vehicle has run-at tires, there is no spare tire
and no tire changing equipment. Your vehicle also has
a Tire Pressure Monitor (TPM) which will alert you if
there is a loss of tire pressure in any of the tires.
SeeTire Pressure Monitor System on page 5-68.
{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. Do not 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 will not 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 will not 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 have driven on
the tire in a deated condition. When a tire has been
damaged, or if you have 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 7-7for details.
5-64

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. Your vehicle also has a Tire
Pressure Monitor (TPM) which will alert you if there
is a loss of tire pressure in any of the tires. 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. Do not 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 5-64andTire
Pressure Monitor System on page 5-68, for additional
information.
{CAUTION:
Special tools and procedures are required to
service a run-at tire. If these special tools
and procedures are not 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 7-16.

Storing a Flat or Spare Tire and
Tools (CTS Only)

Storing a jack, a tire, or other equipment in
the passenger compartment of the vehicle

collision, loose equipment could strike
someone. Store all these in the proper place.

vehicle, you will need to store the at tire in your trunk.
