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, its suitability for winter use is limi‐
ted.
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's side wall by TWI, Tread Wear
Indicator.
