Changing runflat tires
For your own safety, use only runflat tires. No
spare tire is available in the case of a flat tire. Fur‐
ther information is available from a dealer's serv‐
ice center or another qualified service center or
repair shop.
Rotating wheels between axles
Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated in pairs be‐
tween the axles to achieve even wear. Further in‐
formation is available from a dealer's service cen‐
ter or another qualified service center or repair
shop. After rotating, check the tire pressure and
correct, if needed.
Rotating the tires is not permissible on vehicles
with different tire sizes or rim sizes on the front
and rear axles.
Storing tires
Tire inflation pressure
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Storage
Store wheels and tires in a cool, dry and dark
place.
Always protect tires against all contact with oil,
grease, and solvents.
Do not leave tires in plastic bags.
Remove dirt from wheels or tires.
Run-flat tires
Concept
Run-flat tires permit continued driving under re‐
stricted conditions even in the event of a com‐
plete loss of tire inflation pressure.
General information
The wheels consist of tires that are self-support‐
ing, to a limited degree, and possibly special
rims.
The support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the event
of a tire inflation pressure loss.
Follow the instructions for continued driving with
a flat tire.
Safety information
Warning
Your vehicle handles differently with a run-flat
tire with no or low inflation pressure; for in‐
stance, your lane stability when braking is re‐
duced, braking distances are longer and the
self-steering properties will change. There is a
risk of accident. Drive moderately and do not
exceed a speed of 50 mph/80 km/h.
Label
The tires are marked on the tire sidewall with
RSC Run-flat System Component.
