Truck and bus tyres - Method for measuring relative wet grip performance - Loaded new tyres
This document specifies the method for measuring relative wet grip braking performance index to a reference under loaded conditions for new tyres for use on commercial vehicles on a wet-paved surface.
The methods developed in this document are meant to reduce the variability. The use of a reference tyre is necessary to limit the variability of the testing method procedures.
This document applies to all commercial vehicle, truck and bus tyres.
This document does not apply to:
—   tyres fitted with additional devices to improve traction properties (e.g. studded tyres);
—   professional off-road tyres.
