teh ra1 and r888 are still Rcomps, and so track orientated. beacause our cars are so light and used seldomly in the wet, those tyres are frequently used as daily drivers. in teh rain, and real rain, not just wet pavement, i would chose not to be on those tyres driing around town.
for a daliy driver tyre that can handle rain, and pass the DOT's 140 treadwear rating, 15" Bridgestone Potenza RE01R (i have), Toto R1R, or the new Dunlop Direzza z1 star spec would be fine choices.
