Cadillac 2007 CTS, Owner'S Manual, Page: 401 / 518

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 488 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 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 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.
