In order to provide standardised information on fuel efficiency, wet grip and external rolling noise, the European Union is to introduce a compulsory label for all new tyres. By November 2012 all relevant new tyres sold in Europe must carry this EU label.
The label is intended to give end-users some essential information to help them when choosing new tyres.

Exemptions from labelling are motorcycle tyres   ...re-treaded tyres, 4WD and all-terrain tyres, Racing/sports car tires, Tyres for cars made before 1 Oct 1990
