Tire inflation pressure specifications
The tire inflation pressure table contains all
tire inflation pressure specifications for the
specified tire sizes at the ambient tempera-
ture. The tire inflation pressure values apply
to tire sizes approved by the manufacturer
of the vehicle for the vehicle type.
To identify the correct tire inflation pres-
sure, please note the following:
– Tire sizes of your vehicle.
– Maximum permitted driving speed.
Use on a racetrack
The tires heat up while driving. The tire in-
flation pressure increases with the tire tem-
perature.
After a period of intensive driving, correct
the tire inflation pressure in the heated
tires to the tire inflation pressure values
specified by the vehicle manufacturer.
After they have been used on a racetrack,
allow the tires to cool down for at least
2 hours. Reset the tire inflation pressure of
the cold tires to the tire inflation pressure
values specified by the vehicle manufac-
turer.
After correcting the tire inflation pressure,
carry out a reset of the Tire Pressure Moni-
tor TPM.

Mobility System
Concept
With the Mobility System, minor tire dam-
age can be sealed temporarily to enable con-
tinued travel. To accomplish this, sealant is
pumped into the tires, which seals the dam-
age from the inside.
General information
– Follow the instructions on using the
Mobility System found on the compres-
sor and sealant container.
– Use of the Mobility System may be inef-
fective if the tire puncture measures ap-
prox. 1/8 inches/4 mm or more.
– Contact a dealer's service center or an-
other qualified service center or repair
shop if the tire cannot be made drivable.
– Do not remove foreign bodies that have
penetrated the tire. Only remove foreign
objects if they are visibly protruding
from the tire.
– Pull the speed limit sticker off the seal-
ant container and apply it to the steer-
ing wheel.
– The use of a sealant can damage the
TPM wheel electronics. In this case,
