I've got 5+2 on mine and the way it was explained to me was i didn't need the recall +2 spacers if I ran this wheel? Who really knows? Not trying to steal your thread but I have a question too, I hear about guys running wide tires all the way around but nobody running skinnies why? more HP delivery and every mud truck, or hill climb truck, or rock crawler has skinny tires why not a rhino?
