last time I bought them was at an independent garage (those are hard to find too!) but they make "river tubes" now - extra heavy duty swimming pool floats. My kids just bought some to float the Salt River two weeks ago. Sporting goods store.

this guy seems to sell them too: http://www.squidoo.com/inner_tubonia



remember, car tire sizes are really too small - good for your ice chest maybe, but tractor sizes are best
