Ahhhh Tyres, my speciality. lol. As stated they are fully road legal mate, just be very very weary of standing water, because things can get very dangerous. There will be immense grip in the dry though. They also wear very very quickly, in-fact Joe from Banzai Magazine as only managed to do 1,000 or so miles from a set of R888s which is pretty patheic to be honest. If you are after a very good road tyre though mate i would recommend either Toyo T1-Rs, Yokohama Parada Spec-2s or the new Goodyear Eagle F1 Assyimetric.
