Wheels and tires
Recommended tire brands
Tire types are developed for each vehicle and
optimized specifically for the individual require-
ments of that vehicle, e.g.:
▷ Handling.
▷ Comfort.
▷ Noise characteristics.
Specially developed tires are marked with
a star on the tire sidewall. After replacing
wheels and tires, the vehicle manufacturer rec-
ommends using star-marked tires again. The
vehicle manufacturer recommends that you
use tires of the same make and tread design.
New tires
Tire traction is not optimal due to manufactur-
ing circumstances when tires are brand new.
Drive conservatively for the first
200 miles/300 km.
Retreaded tires
Warning
Retreated tires can have different tire casing
structures. With advanced age the service life
can be limited. There is a risk of accident.
The manufacturer of the vehicle does not rec-
ommend the use of retreaded tires.
