Ok guys I am tryin to figure out how ppl are runnin 28's 29.5's on formeman 500's??? Right now I am runnin 27" swamp witches and it does ok in some mud but in the thicker stuff when you shift in to 2nd gear it falls flat on its face! I was runnin 27' outlaws and I got stuck one day in some thick stuff and the tires wouldnt even turn over in 1st gear and they would move barley in reverse! I am wanting to run 28's on mine but I am afraid its not gunna pull em that well???
