Storage
If the sport tires are not used for a long period of
time, we recommend removing the wheels from
the vehicle and lowering the tire inflation pres‐
sure to half the level specified by the manufac‐
turer.
Store wheels or sport tires in a clean, dry, and
dark place at temperatures above 32 ℉/0 ℃.
Use on the road
The sport tires meet the legal regulations for use
on public roads.
After being used on a racetrack, the sport tires
may no longer be suitable for road use. There‐
fore, after they have been used on a racetrack,
check the sport tires against the legal regulations
for use on public roads, for instance the mini‐
mum tread depth.
Use on a racetrack
General information
Inspect the sport tires for damage, foreign ob‐
jects lodged in the tread, and tread wear every
time before using them on a racetrack.
Bring the sport tires to the correct temperature
for use on a racetrack. To do this, drive a few cir‐
cuits with an appropriate driving style.
Intensive use
After an extended period of intensive driving on a
racetrack and driving over curbs or leaving the
roadway, the sport tires can become damaged.
Inspect the sport tires for damage, foreign ob‐
jects lodged in the tread, and tread wear. The
wheel must be removed in order to inspect the
outside and inside of the sport tires. Have the
sport tires checked by a dealer's service center
or another qualified service center or repair shop.

Tire pressure
General information
Check the tire inflation pressure regularly and
correct it if necessary, taking the regulations for
use on the road or a racetrack into account.
Tire pressure specifications
The tire inflation pressure table contains all tire
inflation pressure specifications for the specified
tire sizes at the ambient temperature. The tire in‐
flation pressure values apply to tire sizes ap‐
proved by the manufacturer of the vehicle for the
vehicle type.
To identify the correct tire inflation pressure,
please note the following:
▷ Tire sizes of your vehicle.
▷ Maximum speed for driving.
Use on a racetrack
The tires heat up while driving. The tire pressure
increases with the tire temperature.
After a period of intensive driving, correct the tire
inflation pressure in the heated tires to the tire in‐
flation 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. Cor‐
rect the tire inflation pressure of the cold tires to
the tire inflation pressure values specified by the
vehicle manufacturer.
After correcting the tire inflation pressure, carry
out a reset of the Tire Pressure Monitor TPM.
Tire repair set
Principle
With the tire repair set, minor tire damage can be
sealed temporarily to enable continued driving.
