22 sand stars on a 9 inch wide rim.. best i have ridden yet sold my buddies on them aswell from 20, especially if you ride big soft dunes the flotation is awsome, launches are better bike sits level not ass down so it turns better and does not lift the front as bad.. thats my .02
and they look meaty as hell on the bike as well.
haullers are great for drag but not only are hard to ride in the dunes but they throw alot of roost wich makes it a pain to ride behind so guess what you got haulers back of the pack.The sand stars throw a little roost but its tolerable, sand sharks and sand skates less than stars.aesome for duning slide really easy but dont hook as hard so there ya go.
