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 Assistance. For phone numbers and Roadside
Service details see Roadside Service on page 8-6.
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 run-flat tires have sensors that
are part of the Tire Pressure Monitor System (TPMS).
See Tire Pressure Monitor System on page 6-59.
These sensors contain batteries which are designed to
last for 10 years under normal driving conditions.
See your dealer if you ever need to have a wheel
replaced, or if the sensors 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.
