(Y) above 300 km/h/186 mph
Tyre tread
Summer tyres
The tyre tread depth should not be less than
3 mm, 0.12 in, otherwise there is a high risk of
aquaplaning.
Winter tyres
The tyre tread depth should not be less than
4 mm, 0.16 in, otherwise its suitability for winter
use is restricted.
Minimum tread depth
Wear indicators are distributed around the cir‐
cumference of the tyre. These wear indicators
have the legally prescribed minimum height of
1.6 mm, 0.06 in.
The positions of the wear indicators are identi‐
fied on the tyre sidewall by TWI, Tread Wear In‐
dicator.
Tyre damages
General
Inspect tyres regularly for damage, the presence
of foreign bodies and wear.
Vehicle behaviour that may indicate tyre damage
or other faults:
▷ Unusual vibrations.
▷ Unusual tyre or running noises.
▷ Unusual vehicle response, such as pro‐
nounced pulling to the left or right.
Damage can be caused by the following situa‐
tions, for example:
▷ Driving over kerbs.
▷ Road damage.
▷ Insufficient tyre inflation pressure.
▷ Overloading the vehicle.
▷ Incorrect tyre storage.
Safety notes
WARNING
If the tyres are damaged, the tyre inflation pres‐
sure may be reduced, which in turn could
cause you to lose control of the vehicle. There
is a risk of accident. If you suspect tyre damage
while you are driving, immediately reduce
speed and bring the vehicle to a stop. Have the
wheels and tyres checked. To do so, carefully
drive to a Service Partner of the manufacturer
or another qualified Service Partner or a spe‐
cialist workshop. If necessary, have the vehicle
towed or transported there. Do not repair dam‐
aged tyres. Have them replaced.
WARNING
Tyres can become damaged by driving over
obstacles, for example kerbs or damaged road
surfaces, at high speed. Larger wheels have a
smaller tyre cross-section. The smaller the tyre
cross-section, the higher the risk of tyre dam‐
age. There is a risk of accident and material
damage. If possible, drive around obstacles or
drive over them slowly and carefully.
