Need wheel/tire help

[Corvus]

My stock tires are running out of tread so i've decided to purchase new rims/tires and keep my stock rims for auto-x. I'm thinking oz superleggeras 18inch. First question, where is a good place to get these from? Second, I want tires that will live longer than stock and work well in rain/snow. What would work and what size should i be looking for? Thanks

I think tirerack.com sells OZ rims. Hmm, for all season tires, I was reading up on Continental tires. Forgot what model but it's something like ContiSport or something. It had good ratings. Go check them out. For 18 inch rims, I think you should take them off during the winter since they are more likely to bend than 16's.
