how do you rate them over the KM2’s that’s exactly what I’ll be replacing, have you done much Offroad work so far with them?
I was definitely a fan of the km2, and have really nothing bad to say about them. If the km2/3 came in a comparable size, on a 15" wheel (which is what I wanted to go back to, I've been running 17s with 255/80r17 km2s), I would have considered them. But with the size of these (real 33), the pricing, and the reviews, i had to give them a try.
Keep in mind I'm comparing km2s on a 17" wheel, which is also an E load range tire, vs these on a 15" and C load.
I think these are a little louder than the km2 overall. I don't notice it as much at hwy speeds (it's a soft top...), but between 25-45mph or so, I definitely notice. It is a very low pitch hum though, so not offensive (we'll have to see as they wear). They drive very well on the street, good grip in wet and dry. Good handling and ride but not sloppy. I've been running 32psi, but I haven't done a chalk test to see how close I am ideal pressures.
I did a little snow with them before winter was over and I felt they didn't hook up quite as well as the km2s. My driveway and street are both inclined and it seemed like I struggled more getting going from a stop when heading uphill than I ever did with the km2s. But it was a very small sample to compared to (6 years with km2 and 1 snowstorm with Razr, it could have been more icy than normal).
I did the Mojave road when they were brand new, and was very happy with the desert terrain traction. Went through desert rocks, sand, and mud, and they felt connected in everything. And no chunking of any kind.
I actually just got back from hitting a trail today. Pretty technical with some sandstone, rocks, and lose sand. Lots of steep climb/decent, off camber, ruts). I was very impressed. There were some lines on climbs (on rocks that shouldn't change much) where I would have to scramble a little, adjust my line, and wait for the tires to grab when I had the km2s, but these felt very sticky in the rocks, and barely slipped all day. Also, again no chunking/tears of any kind. Today was also the first time to air down (went to 14psi for this trail), and I was VERY surprised at how soft these were. They felt very pliant when aired down, even to just a hand or foot pushing on them, and the ride was incredible, like floating on clouds. (Again though, comparing E range to C range, and 15 vs 17", so not apples-apples).
So in my couple of months, about 4k miles, and varied terrain, those are my impressions so far after 6 years with km2s.
