The methods developed are meant to reduce variability. The use of a reference tyre is necessary to limit the variability of the testing procedures.
This document applies to all passenger car tyres except for:
— special-use tyres marked with ET;
— T-type temporary spare tyres;
— tyres fitted with additional devices to improve traction properties (e.g. studded tyres).
