Explanation of tyre labels
The data on the label enables you to assess more efficiently the quality of the tyre according to three criteria :
Class A corresponds to the best performance and class G to the worst.
The rolling resistance of your tyres leads to heavy fuel consumption.
The classification enables to assess fuel efficiency per 100km in relation with the reference class A
This class measures the braking capacity of the tyre The shorter the braking distance, the better the class
The test consists in conducting a full emergency braking at 50MPH and to measure the braking distance
The performance variance is calculated from the best class A.
External rolling noise ( in dB)
The rating on the label corresponds to the noise emitted by a vehicle driving at 50MPH recorded by a microphone placed at a 7.5m distance from the track.
