The special tyre tread in combination with
th e optimised tyre compound, means that th
erisk of skidding or hydroplaning on wet
ro ads is inc reased.
In addition, the tyre grip is greatly reduced at
a low outside temp erature and tyre running
te mp erature. #
Switch on the ESP ®
and adapt your
driving style accordingly. #
Use M+S tyres at outside temp eratures
of less than 50 °F. Obse
