Self-supporting run flat tires (SST)*
Self-supporting run flat tires are available as
optional equipment. The vehicle must be
equipped with the Tire Pressure Monitoring
System (TPMS) if tires of this type are instal-
led.
Tires of this type have specially reinforced
sidewalls that make it possible to continue
driving to a limited extent even though the tire
has lost some or all of its inflation pressure.
These tires are mounted on special rims (nor-
mal tires can also be mounted on these rims).
If an SST tire loses inflation pressure, the yel-
low TPMS symbol illuminates in the instru-
ment panel and a text message is also dis-
played. If this happens, reduce speed to not
more than 50 mph (80 km/h). The tire should
TIRE be replaced as soon as possible.
is displayed.
Drive carefully; it may be difficult to determine
which tire is damaged. To find the damaged
tire, check the inflation pressure in all four
tires.

service technicians who are familiar
with tires of this type.
•
SST tires may only be mounted on
vehicles equipped with TPMS.
•
Do not drive faster than 50 mph
(80 km/h) if TPMS indicates that a tire

•
Do not drive farther than 50 miles
(80 km) before replacing a damaged
SST tire.

damaged. A tire of this type cannot be
repaired.
