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 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 flat, 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 filled with air, it provides a cushion between the road
and the wheel. Because you will not 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 have driven on
the tire in a deflated condition. When a tire has been
damaged, or if you have 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. To locate the nearest GM or run-flat
servicing facility, call Roadside Service. See Roadside
Service on page 7-7 for details.
