That's where I got mine. I'm running 17x9s and 245/45/17s all around. My front tires rub a little when the wheel is turned all the way, but it's not bad. You could probably fit some 255s up front but I wouldn't go any bigger than that though. You could fit 255s or maybe 275s on the back, but you'll have to remove the quad shocks (I did). Hope this helps.
