That depends on a few things. Are you lowered, andit depends on the type of tires. I have 255/50 16's on my rear and the quads are fine but sometimes I rub on the outside, But it is because my off set, I can go deeper in. As for the front I did have 245/50 16's and they rubbed only when I got on the brakes hard or a hard brake and turn, but then I got a different model tire (same size and same brand) but I could barly go over a bumb going straight without rubbing, so i had to go to 245/45/16's and I never rub, Like I said though I'm lowerd, I don't know how much because it was lowerd when I got it.
