Wheels and tires
MOBILITY
▷ Tire inflation pressure too low.
▷ Vehicle overloading.
Minimum tread depth
▷ Incorrect tire storage.
Safety information
Warning
Damaged tires can lose tire inflation pressure,
which can lead to loss of vehicle control. There
is a risk of accident. If tire damage is suspected
while driving, immediately reduce speed and
stop. Have wheels and tires checked. For this
purpose, drive carefully to the nearest dealer’s
service center or another qualified service cen‐
ter or repair shop. Have vehicle towed or trans‐
ported as needed. Do not repair damaged tires,
but have them replaced.
Wear indicators are distributed around the tire's
circumference and have the legally required min‐
imum height of 0.063 inches/1.6 mm.
The positions of the wear indicators are marked
on the tire sidewall with TWI, Tread Wear Indica‐
tor.
Tire damage
Warning
Tires can become damaged by driving over ob‐
stacles, e.g., curbs or road damage, at high
speed. Larger wheels have a smaller tire cross-
section. The smaller the tire cross-section, the
higher the risk of tire damage. There is a dan‐
ger of accidents and property damage. If possi‐
ble, avoid driving over objects or road condi‐
tions that may damage tires, or drive over them
slowly and carefully.
General information
Inspect your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Driving over rough or damaged road surfaces, as
well as debris, curbs and other obstacles can
cause serious damage to wheels, tires and sus‐
pension parts. This is more likely to occur with
low-profile tires, which provide less cushioning
between the wheel and the road. Be careful to
avoid road hazards and reduce your speed, es‐
pecially if your vehicle is equipped with low-pro‐
file tires.

functions:

MOBILITY
Wheel and tire combination
General information
Recommended tire brands
You can ask the dealer's service center or an‐
other qualified service center or repair shop
about the correct wheel/tire combination and
wheel rim versions for the vehicle.
Safety information
For each tire size, the manufacturer of the vehi‐
cle recommends certain tire brands. The tire
brands can be identified by a star on the tire
sidewall.
Warning
Wheels and tires which are not suitable for your
vehicle can damage parts of the vehicle, for in‐
stance due to contact with the body due to tol‐
erances despite the same official size rating.
There is a risk of an accident. The manufac‐
turer of your vehicle strongly suggests that you
use wheels and tires that have been recom‐
mended by the vehicle manufacturer for your
vehicle type.
New tires
Tire traction is not optimal due to manufacturing
circumstances when tires are brand-new; they
achieve their full traction potential after a break-in
time.
Drive conservatively for the first
200 miles/300 km.
Warning
Incorrect wheel/tire combinations will have a
negative impact on the vehicle's handling and
on the function of a variety of systems, such as
the ABS Anti-lock Brake System or DSC Dy‐
namic Stability Control. There is a risk of acci‐
dent. To maintain good handling and vehicle
response, use only tires with a single tread con‐
figuration from a single manufacturer. The
manufacturer of the vehicle recommends that
you use wheels and tires that have been rec‐
ommended by the vehicle manufacturer for
your vehicle type. Following tire damage, have
the original wheel/tire combination remounted
on the vehicle as soon as possible.
Retreaded tires
Warning
Retreaded tires can have different tire casing
structures. With advanced age the service life
can be limited. There is a risk of an accident.
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
The manufacturer of the vehicle does not rec‐
ommend the use of retreaded tires.
Winter tires
Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires provide
better winter traction than summer tires, they
usually do not provide the same level of perform‐
ance as winter tires.
