i have a question that fits here. i am looking at a set of 18x8.5. at the moment i am not sure of the of set. the tires are 225's. i dont know how to word this, how small or large of an off set can i go? like where is my limit before 1 of 2 things happen. either it looks stupid or i rub beyond the point that rolling my fenders wont even work? thanks for the help.
