I just got BFGoodrich G-Force Sports in 225/45/18 and put them on my stockers. I barely rub, it's like taps my fender, nothing really crazy. I'm on BC coilovers and no gap in the front and about a finger in the rear. With 2 passengers, no rub over bumps. With this size, you'll notice feeling bumps. It's so much smoother. But the only complaint I have is that the sidewalls seem to flex more.
