ported as needed. Do not repair damaged tires,
but have them replaced.
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 may be a
risk of accident and risk of damage to property.
If possible, avoid driving over objects or road
conditions that may damage tires, or drive over
them slowly and carefully.

Safety information
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.
Warning
Mounted steel wheels can cause technical
problems, for instance unexpected loosening of
the lug bolts and damage to the brake discs.
There is a risk of accident. Do not mount steel
wheels.
Warning
Incorrect wheel/tire combinations will impair the
vehicle's handling characteristics and a variety
of system functions, such as the Antilock Brak‐
ing System (ABS) or Dynamic Stability Control.
There is a risk of accident. To maintain good
handling and vehicle response, use only tires
with a single tread configuration from a single
manufacturer. The manufacturer of the vehicle
recommends that you use wheels and tires that
have been recommended by the vehicle manu‐
facturer for your vehicle type. Following tire
damage, have the original wheel/tire combina‐
tion remounted on the vehicle as soon as pos‐
sible.
