Right now I have the 21" staggered wheel setup. I know it's early but I got a set of all season rims and tires as part of my deal so my question is do they have to be staggered also? They are actually 245/55r18's. I don't think the dealer would have given them to me if they wouldn't work but I just wanted your opinions before I go to put them on in November and get a big surprise.
