E Grade – Below average fuel efficiency, however there may in some cases be a good reason why the rolling resistance is higher, for example where tyres are specifically designed for more grip, such as sports car tyres or winter tyres.
B Grade – Nearly the best quality tyres to stop in the wet, stopping only 3m more than a grade A tyre but on average 15m shorter than a car on grade G tyres (on a wet road when braking from 50mph – testing according to regulation EC1222/2009)
3 Bars – At least 3dB's above future EU noise limit (although meets current limit)
73 dB – Exterior noise level measured in decibels (dB). The lower the exterior noise level the better the environment near busy roads
