ARNI NGRisk of aquaplaning due to
insu1cient tyre tread
Insu1cient tyre tread will result in reduced
tyre grip.
The risk of aquaplaning is increased on wet
ro ads, especially when the speed of theve hi-
cle is not adap tedto suit the conditions. #
Thus, you should regula rly ch eck the
tread dep thand the condition of the
tread across the entire width of all tyres.
Minimum tread dep thfor:
R Summer ty res: 3 mm
R M+S tyres: 4 mm #
For saf etyre asons, replace the tyres
before the legall y-prescribed limit forthe
minimum tread dep thisreached. Car
