go 265 fronts and 305 rears... with your offsets you have TONS of room!!! I am running those sizes on 20's and much more aggressive wheel setup! Go big or Go home hehe
on a good choice of wheels!
Toyo's, Falken's, michelin's, Pirelli's, Dunlop's, and all the other Major manufacturers will be good for you.
If your not tracking your car then I would go with 1 or 2 levels down from their flagship models to save you money. but if your all for performance Tire Rack does some great comparisons to help you choose
