you might want to look at the ITP Terracross radial.It's a super lightweight radial made for trail use.I'm more than likely going to go that route very soon as i just destroyed one of my swamp fox tires on a ride today....I somehow peeled a complete tread lug right off the tire casing and it's showing bare cords.......the rocks were very big and sharp,big as in the size of atv's and it was crawlin time.
