Tire treadSummer tires
Do not drive with a tire tread depth of less than
0.12 in/3 mm.
There is an increased danger of hydroplaning if
the tread depth is less than 0.12 in/3 mm.
Winter tires Do not drive with a tire tread depth of less than
0.16 in/4 mm.
Below a tread depth of 0.16 in/4 mm, tires are
less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
General information
Inspect your tires often for damage, foreign
objects lodged in the tread, and tread wear.
Notes
Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Indications of tire damage or other vehicle de‐
fects:▷Unusual vibrations during driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
Damage can, e. g., be caused by driving over
curbs, road damage, or similar things.
In case of tire damage
If there are indications of tire damage, re‐
duce your speed immediately and have the
wheels and tires checked right away; other‐
wise, there is the increased risk of an accident.
Drive carefully to the nearest service center. If
necessary, have the vehicle towed.
Otherwise, tire damage can be life-threatening
for vehicle occupants and other traffic partici‐
pants.◀
Repair of tire damage
For safety reasons, the manufacturer of
your vehicle recommends that you do not have
damaged tires repaired; they should be re‐
placed. Otherwise, damage can occur as a re‐
sult.◀
Changing wheels and tires
Mounting Information on mounting tires
Have mounting and balancing performed
only by a service center.
If this work is not carried out properly, there is
the danger of subsequent damage and related
safety hazards.◀
