Hey man! I love my bigger tires as well! I love the look and everything about them, haven't measured if they have done anything to my mpg but it if has it's not very noticeable. As for rub, sometimes they rub at full lock and sometimes they don't, but the wheel has to be completely turned one way in order for them to rub, any less than that and they don't rub at all. I highly suggest them!
