and adapt your
driving style accordingly. 0007
Use M+S tyres at outside temp eratures
of less than 50 °F. Obse

re placing tyres:
R Countr y-specific requirements for tyre
appro valth at define a specific tyre type for
yo ur vehicle.
Fu rthermore, the use of cer tain tyre types in
cer tain regions and areas of operation can
be highly beneficial.
R Only use tyres and wheels of the same type
(summer tyres, winter tyres, MOEx tended
