[QUOTE=RacerXXL;524136]I ran 33x12.50x15 on OEM rims with the articulator lift and a 2" body lift for some time. No cutting required on the rear and only minor plastic trimming required on the front. The rear tire when fully stuffed will either rub on the frame or the inner fender a bit. All I did was to fold over the panel edge of the inner fender to protect the tires from the potentially sharp panel edge.
Currently I'm running 4.75 BS but no pics with that setup but it flexes a bit better now than it did with the OEM rims.
OEM rims and 33's in the pics below and it will go a bit farther now with the 4.75 BS rims.
BTW Racer: your X is awesome!
