For temps above 45-50 degrees you can't go wrong with Michelin Pilot Super Sports. The newer 4S is supposed to be great, but I haven't driven on them. For temps below that I'm a big fan of the Michelin Pilot AS/3+.
Neither are cheap, but quality rarely is. If you're looking for a lower priced tire, post up your budget.
Yeah, I'm a tire geek.
