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 vehicle’s run-flat tires
can operate effectively with no air pressure for up
to 50 miles (80 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 deflated run-flat tire, check
with an authorized run-flat tire service center, as
soon as possible, 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. To locate the nearest GM
or authorized run-flat servicing facility, call
Roadside Service. See Roadside Service on
page 531 for details.
{CAUTION:
Run-flat tires are constructed differently
than other tires and could explode during
improper service. You or others could be
injured or killed if you attempt to repair,
replace, dismount, or mount a run-flat tire.
Let only an authorized run-flat service
center repair, replace, dismount, and
mount run-flat tires.
The valve stems on your vehicle’s run-flat tires
have sensors that are part of the Tire Pressure
Monitor System (TPMS). These sensors contain
batteries which are designed to last for 10 years
under normal driving conditions. See your GM
dealer, if the TPMS sensors or a wheel ever need
replacement.
Notice: Using liquid sealants can damage the
tire valves and tire pressure monitor sensors in
your vehicle’s run-flat tires. This damage would
not be covered by warranty. Do not use liquid
sealants in your vehicle’s run-flat tires.
