stang13....the offset on my wheels are zero (20X9)....I'm not sure what width and offset is available in the Rockstar's but there is a good chance if you go with a negative offset (tire sticking farther outside the wheel well) you could run into problems rubbing thus requiring a leveling kit. If I was offroading with my truck there could definitely be some conditions where the tires would rub bad....hope this helps.
