Run-Flat Tires
Your vehicle, when new, had run-at tires. There’s no
spare tire, no tire changing equipment and no place to
store a tire in the vehicle. Run-at tires perform so well
without any air that a Tire Pressure Monitor (TPM) is
used to alert you if a tire has lost pressure.
If a tire goes at, you won’t need to stop on the side of
the road to change the tire. You can just keep on
driving. The shorter the distance you drive and the
slower the speed, the greater the chance that the tire will
not have to be replaced. If you drive on a deated
run-at tire for 50 miles (80 km) or less and at speeds of
55 mph (90 km/h) or less, there is a good chance that
the tire can be repaired. The tire can operate effectively
with no air pressure for up to 125 miles (201 km) at
speeds up to 55 mph (90 km/h), but the tire would then
have to be replaced. When a tire is lled with air, it
provides a cushion between the road and the wheel.
Because you won’t have this cushion when driving on a
deated 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 deated condition. When a tire has been
damaged, or if you’ve driven any distance on a
run-at tire, check with an authorized run-at tire service
center to determine whether the tire can be repaired
or should be replaced. To maintain your vehicle’s run-at
feature, all replacement tires must be self-supporting
tires. As soon as possible, contact the nearest
authorized GM or run-at servicing facility for inspection
and repair or replacement. To locate the nearest GM
or run-at servicing facility, call Roadside Assistance.
For phone numbers and Roadside Service details
seeRoadside Service on page 8-6.

3. Lift the vehicle with the jack, making sure the jack
spans at least two of the crossmember ribs (B).
For more information, seeDoing Your Own Service
Work on page 6-4.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly. See
Tires on page 6-46for additional information.

{CAUTION:
When the TIRE FLAT MAX SPD 55, REDUCED
HNDLG message is displayed on the Driver
Information Center, 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 TIRE FLAT MAX SPD 55,
REDUCED HNDLG message is displayed. Drive
cautiously and check your tire pressures as
soon as you can.
If the TPM system detects a tire pressure below
5 psi (34 kPa), the TIRE FLAT MAX SPD 55, REDUCED
HNDLG warning message is displayed on the Driver
Information Center (DIC). SeeDIC Controls and
Displays on page 3-61andDIC Warnings and Messages
on page 3-64for information and details about the
DIC operation and displays.
{CAUTION:
Special tools and procedures are required to
service a run-at tire. If these special tools and
procedures aren’t used you or others could be
injured and your vehicle could be damaged.
Always be sure the proper tools and
procedures, as described in the service
manual, are used.
Notice:Using liquid sealants can damage the tire
valves and tire pressure monitor sensors in your
run-at tires. This damage would not be covered
by warranty. Don’t use liquid sealants in your
run-at tires.
To order a service manual, seeService Publications
Ordering Information on page 8-12.
If a tire goes at, the stability control system will turn on
automatically even if it was disabled by the driver.
When a at tire condition exists the StabiliTrak
®system
cannot be turned off. SeeStabiliTrak®System on
page 5-10.
