Dunlop SP WinterSport 4D (225/50 R17 94H) MFS ROF BMW

Rolling Resistance(A-G)

F Grade – Not a very fuel efficient tyre – could be up to 6% worse than a grade A tyre. 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.

Wet Grip(A-G)

C Grade – Above average quality tyres to stop in the wet, stopping only 6m more than a grade A tyre but on average 12m shorter than a car on grade G tyres (on a wet road when braking from 50mph – testing according to regulation EC1222/2009)

Sound Wave(1-3)

1 Bar – Below future EU noise limits

Noise(67-79 Db)

69 dB – Exterior noise level measured in decibels (dB). The lower the exterior noise level the better the environment near busy roads
