Regulation no. 1222/2009/EC states that all tyres sold in EU countries
produced after 1 July 2012 must bear a label (as shown in the bottom
right) containing important information on performance. The aim of
the regulation is to provide consumers with more information on safety
(wet grip) and environmental (rolling resistance and external rolling noise)
issues in order to promote the use of safer, quieter and more efficient tyres.
The label provides the following information:
Fuel consumption
The fuel consumption of a vehicle is influenced by the tyre rolling
resistance. There is a scale with 7 levels, from A to G, on the left of the
label where "A" indicates the best tyre class for reducing fuel consumption
with lower rolling resistance.
