Hey guys; i have a 06 GT w/ just a cat back sys and looking into tires in the near future. I dont plan on going nutz w/ the car just some basic bolt ons so this is not going to be some crazy 500hp animal.

I have kumho 245/50/18 wrapped all around my stock 18" bullit style rims and im looking into some DRs for the rear. Couple of questions

I want to see if their any DR that can been driven in the rain?

Does it make more sense to buy two extra rim and tires? if so; what size?

any fav brand? Nitto; mt; what

My car is a DD and i do go the track.
