I recently purchased a set of Kumo KL71 MT, and couldn't find much for reviews so thought I would start my review.
They are a directional tire, although besides the fact that your spare only has a 50% chance of being on the right side, I don't know why that would be bad, certainly hasn't stopped me from backing out of holes I couldn't drive though.
The tires look great.
I only have about 200 km on them so far.
On road they are fairly quiet. And my biggest surprise is how well they handled the snow and packed snow.
Offroad they have been excellent, and clean out extremely well.
I keep updating as I get the chance to wheel against more tires.
