Making the rear match the front isn't an option, then they would both stick out too far My wife is VERY picky with her vehicles, beyond the level of most car guys and she wouldn't stand for them sticking out at all, let alone the fact that it would get the truck dirty faster.

I've never heard that it was only the 4wd before though, odd. With her 15x7 TT2s it's already visible that they are out further in the front
