I stood up an ASX tire in the mounted postion right behind a good year rawhide tire that was mounted to the right rear axle on my Mudd-Ox , and the wider 26 " inch ASX tire makes the 25 " inch rawhide tire really look small by comparison. The ASX tires will be better for most off road conditions, but if you,re a serious mudder, Tim,s swimming tracks on a Mudd-Ox are awesome!
