Will they fit?
If you were talking about OEM 17's or 18's, they would fit. However the OEM 20 inch wheels have more backspacing. There have been issues of some MT's touching the upper control arm/ball joint when useing OEM 20's.
Keep in mind that the touching/rubbing is very slight. So slight that it varys from truck to truck and from one tire to another. A 33x12.50-20 (305/55-20) all terrian tire or even a MT with less aggressive side lugs may not rub.
