At Reifen-Immler they’ll put the Polar Ice Ride Tread on the classic car tires that I’m going to use on the R1. The Cross 1 pattern – for the rear tire – will be used in its full width. From the Cross 3 pattern – for the front tire – the outside row of nobs will be cut off. An approximately 16 cm / 6 inch wide tread will remain.
