That hill in the video, did anyone go up it with KM2's?
I don't recall any KM2's specifically.
But any tire could get you up; it really depends on the rig, amount of air, lockers, etc.
I have MTR/K's on a JK with 4.56 gears, open diffs, and autotrans. I tried the hill 7 times at street pressure and couldn't get up; went down to 17 psi and went up like it was my driveway.
The guy in the teal XJ is twice as good a driver as me and has a locker up front; he didn't air-down and really had to work the climb even with SS tires.
The week before, a guy in a beat 4-cylinder TJ went right up with street tread, open diffs, and street pressure. A light rig doesn't need as much "help".
Go figure, right?
