ISO/TC 31/WG 8 - Methods for measuring snow and ice grip performance

This document establishes a test method for evaluating the wear caused to the road surface by passenger car tyres and light truck tyres that are equipped with studs.

This document specifies the method for measuring the relative ice grip performance index of a candidate tyre compared with a reference tyre under loaded conditions for new tyres intended to be used for passenger cars on surfaces made of ice. This document applies to all passenger car tyres, except for T-type temporary-spare tyres.
