i have been wondering how a max 2 with tracks on rear and center tires and the front wheels '' freewheeling '' would work . front wheels would be unchained so there would be no chain windup. otherwise you have to go to a bigger tire on front to match other 2 diameter tracked tires. front wheels would be smaller and not touching the ground all the time . been thinking of giving it a try just for fun and see the results . j.b.
