I bought the 03 Regal with aftermarket rims and now that winter is rolling around I would like to prepare myself for the upcoming MN winter, by doing so I will need to purchase a stock set of (insert w-body here) while more commonly seeing torque stars, etc on CL. Obviously, I don't care about looks over performance of the application but my question to you would be... Do I need to worry that much about tire size and being lowered as far as rubbing? I have SSC's on 18's with 245/45/18 tires and no issues at all, maybe this is a dumb question but I'd hate to buy brand new tires + rims that come with a bunch of issues because of an error on my part.
