Pursuant to the Regulation of the European Parliament and Council (EC) No. 1222/2009 from November 1, 2012. all tires for passenger cars, delivery vans and lorries must be labeled.
The current regulation on the labeling of tires included three parameters: class fuel efficiency , traction on wet surfaces and external class rolling noise and the measured value (in dB).
How to read the label?
- Fuel efficiency class Tire profitability is based on the rolling resistance coefficient, RRC As kg of drag per ton of vehicle (kg / t) (the lower the RRC value, the better for fuel (tire performance) .The fuel efficiency index is shown on the label as (1) Marked on a colored AG scale A – the most efficient tire , with the least rolling resistance, will save fuel, the lowest exhaust emissions G – the least efficient tire with the highest rolling resistance, consumes the most fuel, the highest emission of exhaust gases.
Adhesion refers to the safety performance of tires, i.e. reflects the braking ability of a tire on a wet road. The wet grip index is shown on the label and the designated letter in the AG scale, as well as for fuel efficiency.
A – the safest tire , the shortest braking distance. G – the worst tire grip , the longest braking distance.
- Noise – determines the noise generated by the tires of a passing car. The noise level is measured in decibels (dB) and depicted by means of a three-point scale in the form of waves. 1 wave – the quietest tire . 3 waves – the loudest tire . In addition, the noise level in dB is also given.
