On November 1, 2012, the new EU regulation 1222/2009 on the labeling requirements for motor vehicle tires comes into effect.
The tire label applies to all new tires produced after July 1, 2012. The new label will make it easier to identify and compare three important performance characteristics: braking performance in wet conditions, noise levels and fuel efficiency.
Fuel savings depend fundamentally on the vehicle and driving conditions. If a vehicle is fitted all round with Class A tires as opposed to Class G, fuel consumption can potentially be reduced by up to 7.5 %. This value can be even higher with commercial vehicles.
The degree of effectiveness depends fundamentally on the vehicle and driving conditions. With full brake application, the braking distance can be shortened by up to 30 % on a vehicle fitted all round with Class A as opposed to Class G tires. On a “normal” car travelling at a speed of 80 km/h, the braking distance on a road surface with average grip can be up to 18 m shorter.
The external rolling noise of the tire is measured in decibels. It should be noted here that the external rolling noise of the tire does not correlate with the noise in the vehicle interior
