[quote=charlescarlis]Ditto - tires can be had at wally world on-line for about $30 each - the axle can be replaced with 1 and 7/8" O.D. 6061 T-6 PIPE (not tube) instead of the supplied 2" O.D. tube for a little more strength. I bowed my original one with my 21SE, fully loaded (600+ pounds). The pipe has a way thicker wall and is much, much cheaper. The 1/8 smaller diameter doesn't bother the "needle bearings" (round HDPE rods). The only thing you truly can't find are those rims - they are unique and special to the success of getting the big, balloon tires to work. BTW, hard plastic is only good for hard surfaces. Once you go to good balloon tires and balance the boat well, a couple of moderately strong people can move it without too much incline.[/quote]
