Run-Flat Tires (CTS-V)
If your vehicle has run-flat 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. See
Tire Pressure Monitor System (CTS-V) on page 5-65.

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 flat, 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
filled with air, it provides a cushion between the road
and the wheel. Because you won’t have this cushion
when driving on a deflated run-flat 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 deflated condition. When a tire
has been damaged, or if you’ve driven any distance on
a run-flat tire, check with an authorized run-flat tire
service center to determine whether the tire can
be repaired or should be replaced. To maintain your
vehicle’s run-flat feature, all replacement tires must
be self-supporting tires. As soon as possible,
contact the nearest authorized GM or run-flat servicing
facility for inspection and repair or replacement.
