As far as I'm aware, yes, yes they will. I've seen in person a 15x8" with a 265/50!?!
Everything stock from what I could see, not sure why, more weight at the wrong end for a stock car.
If you don't have mags yet, why not just purchase a 7" instead?
If you have a couple already I can see why the question. Wait for confirmation from others.
Can't think of what BS you'd need. It's 5:18am down here and I haven't been to sleep lol
