Self-supporting run flat tires (SST)
Self-supporting run flat tires are available as
optional equipment on certain models.
Tire sealing system* – general
information
WARNING
SST tires should only be mounted by
service technicians who are familiar
with tires of this type.

Certain models are equipped with a tire
sealing system* that enables you to tempo-
rarily seal a hole in the tread surface and re-
inflate a flat tire, or to adjust a tire’s inflation
pressure.
The vehicle must be equipped with one of the
tire pressure monitoring systems if tires of
this type are installed.
SST tires may only be mounted on
vehicles equipped with a tire pressure
monitoring system.
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).
Do not drive faster than 50 mph
(80 km/h) if the monitoring system indi-
cates that a tire has lost inflation pres-
sure.
Do not drive farther than 50 miles
(80 km) before replacing a damaged
SST tire.
•
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
be replaced as soon as possible.
Drive carefully and avoid e.g., hard
braking or fast turns.
•
•
SST tires must be replaced if they are
damaged. A tire of this type cannot be
repaired.
Introduction

•
The tire sealing system consists of an air
compressor, a container for the sealing com-
pound, wiring to connect the system to the
vehicle’s electrical system via one of the 12-
volt sockets, and a hose used to connect the
system to the tire’s inflation valve.

NOTE
The tire sealing system's compressor has
been tested and approved by Volvo.
