I've been running RE050A's on mine for about 3-4 years now. I really rate them - maybe not as good as the old SO3s (gawd love em) but still a great tyre in both wet and dry i.e. UK weather! If yours sits in a garage all winter then there are undoubtedly better dry tyres out there.
I have 265 35 18 rears and 215 40 17 fronts - these are Y rated (upto 186mph).
