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.<\/p>\n
This document applies to all passenger car tyres, except for T-type temporary-spare tyres.<\/p>\n
