If you've got a utility and some cash to burn, Interco, the company that makes Super Swampers has the SSR in a size that will fit on a quad. I've seen sets on a new King Quad 750 at Suzuki in Sioux Falls and also on a Brute Force 750 at Mid American (don't but there, way to expensive). I've even seen a set on a Polaris RZR that sits at Garys Gun Shop once in a while and he had the tires tread custom cut, man they look awesome, a little heavy for my taste. If you want to go for something cheaper I think all the major tire shops in Sioux Falls could help you out. Hope that helps.
