I wonder if someone could advise me of the biggest tire I could put on my 2013 Mustang that would definitely not rub in any circumstance. Which includes front tires rubbing while turning or going through a dip in the road. etc. I am thinking that a 19" is about the largest rim size. But what would be the offset in 18 or 19 inch that I would keep the same 4 equal rims for tire rotation? And what size tires would go with the rims. I like a deep rim (offset) but don't want bigger tires in the back then front. Want everything the same. Thanks so much
