I'm thinking about getting a set of wheels and tires to use all season for driving in pittsburgh. i have the stock steelies and goodyears, but they kind of suck, and i have the 18" trd's with pirelli pzeroneros, but those are my summer wheels and i dont want to mess them up in pitt.

so could people suggest wheel/tire combos that would be good for east coast city driving ?
17" and 16" would be ideal. how about P6's ?
