You won't be disappointed with the KM3s - they are great in everything I've tried them in - dry, wet, sand, mud. No snow or ice yet.
I've only driven about 200 mls. on the KM3'S so far & looking forward to a couple of Michigan off road trips soon. At slower speeds (still 38psi) they seem a little harsher, but at highway speeds they're as plush as my VR 602's & KO2's. Yes, somewhat noisier than the KO2's, but the guys at my local 4WP were amazed at how the KM3's "balanced up" with very few weights.
I also played with a 2x4 yesterday to check what tire clearences would be & w/o a lift the 37's KM3's would definitely rub on a stock 2018. Definitely like the "37" look but not sure if I want to upgrade to a 2020 before considering a lift.
On another note....I had a long conversation yesterday about "manufacturers spec." sizes vs actual (35" family is spec @ 34.4" actual @ 33.7") with my local 4WP rep. He said it's a huge industry headache especially when working with tight clearances (also rim width & offsets are a factor)! Anyway he has ordered a set of 35x12.50-17 KM3's tires for me to see if they measure closer to "spec"...if they do he will exchange/credit my current tires plus the cost difference of the new tires to make me happy.
