My biggest problem with the BFG MTkm is the weak (by todays standard) sidewall. This is not a tire to take to Delta or where sharp rocks live. BFG gave me a set of prototype km's that are supposed to have a stiffer/stronger sidewall for testing. I figure this is an attempt to compete with the MTR's, but who knows. Of course, the Krawlers seem to be getting alot of attention, but I can't see the typical consumer buying a set for his weekend trail rig like alot of MTR buyers. I figure BFG sees the Krawler as the full-blown competition tire, then will have a better MT available at some point. However, when BFG is not around I run Swampers. I think the SX is the best off road tire currently available for sale to the general public.
