I want maximum grip in the dry, noise levels and fuel consumption aren't that big of a factor.
The only thing keeping me from buying semi slicks is the thought of aquaplanning and spinning out on the highway at the first sign of rain

I have my doubts about going to R17 and a thinner sidewall, as the roads are horrible where I'm from and therefore want to maintain a shred of dignity when going over potholes.
Currently I own a pair of all-season tires and they're friggin useless in the corners, can't wait to wear them out..
