Im looking for new tires for my stang, and want to see what the biggest size tire i can put on the back, without having to do any adjustments, and what the widest i can go is. Most likely going to stick with smaller tires on front, just dont want to have to deal with getting the tires rotated and stuff. But if you have a setup like mine, any advice will be helpful, or if you think i should just go with same tires all around, and what size those should be.
