I just put Nitto 555r's on.
275/50/15's on stock wheels with no spacers.
They fit perfect, look mean, and no rubbing so far.
If they rub, it'll be on the frame rail, so just put a 1/4" spacer behind them.
They hook pretty good to.
Only thing I don't know yet....how long will they last with me driving 50+ miles a day on them....
