New EU Legislation dictates that every new tyre sold within Europe (with a few exceptions*) must be labelled. In a bid to make the label easy to understand it’s designed in a similar way to the labels you’ll see on a new fridge or washing machine.
Explanation of tyre labels
The rolling resistance of your tyres is a key contributing factor in the amount of fuel that your car uses. Low rolling resistance equals better fuel economy and vice versa. The classification enables you to assess fuel efficiency per 100km. Class A corresponds to the best performance and class G to the worst.
This rating provides info on the tyres grip levels on wet roads, A being the best and G being the worst. The rating is calculated by a stopping distance test on a wet road at 50mph
External rolling noise (in dB)
The tyres exterior noise rating is expressed in decibels. One black soundwave indicates the lowest noise level. Three black soundwaves indicates the loudest noise level.
