The Scorpions that come as standard on the Numpty are brilliant tyres, I've heard that they're the same carcass as the Diablo, which has won many fans through the DD race series so when i wear out mine (done 2k miles and they dont look worn much at all) I'll go with whichever comes out cheaper of the two from Steve the TyreMan at Wraysbury Tyres. Get a good DSC discount there too
