I almost had a set of those (I think the KL-41 are the same) after ordering Kumho Road Venture AT 825, and got sent them instead since the 825's were discontinued.
My choice went from Kumho Touring A/S 795 (cheap), to Kumho Road Venture AT 825 (good reviews but discontinued), to Kumho Road Venture AT KL-41 (sent in place of the 825's), to Firestone Destination A/T (salesman mentioned that the Michelins were just a bit more), to the Michelin LTX M/S.
I either read online, or heard somewhere, that since there is no main center tread bar on those Kumhos (KL-41), that there might be an issue that the tire won't track, so they are prone to wandering. You notice anything like that?
My next set of tires might be the Kumho KL61 SAT...
