Can't talk to the mileage just yet, I only have around 7k-8k on them. But I think they're total shit in the rain. 4A is a must if the roads are wet. My 2017 lariat had the wranglers from the factory which were not great in rain either. Then I switched to the ridge grapplers and they were pretty dang good in the rain - i.e. I didn't gave to put in 4A every time it rained.
I'll definitely be changing to something else, as soon as they wear out, probably ridge grapplers again.

I hated the ridge grapplers in the rain. They don't channel well enough in heavy rain and I felt like they were pulled all over the place when ruts were full of standing water. Good in the rain for me is being able to channel water....all tires will slip or slide in the rain with too much throttle or heavy braking.

40k and it’s time to change them before winter. Not great in the rain, always use 4A. Best all around tires I’ve had were Geolanders, but looking at Cooper Discoverer ST Pros

22k on mine and lucky if they see another 4 or 5k before they are done. I am not impressed with wet handling or mileage and looking to change to another tire when these are done.

I bought my Gen 1 with 21000 miles and the original BFGs. I now have 50000 miles with no urgent need to replace before our Michigan Winter. Not fond of wet handling at this tread level though.

I have 38k on the truck, and about 6k of those miles were with my winter TOYO Mts, so about 32k on the stock KO2s and they are close to needing to be replaced.
I did have the KO2s siped after the first winter and that made a big difference in teh rain, but I did notice the rear tires chunked a little more along the lines of the sipes, but I drive a fair amount off road or on rocky and gravel roads, which takes a toll on chunking no matter the tires.
I won't be using KO2s again, mud tires are next, probably Cooper STT Pro (or Mastercraft MTX-same tire from Cooper) mud tires, or Goodyear Wrangler MTs; 10-ply on both.

Had 52K on my first set and only changed them because we were coming into winter. Probably could have safely got 60K out of them.

Very happy with all around traction. I don't do any off road but we do see snow through winter.

These tires get noisy he more they wear. That was probably my only complaint.

I looked at a lot of tire options before I replaced mine and chose to put the same ones back on.

I rotate every 5k miles and run 40 psi

I got about 27k on my original KO2s, they were basically bald at that point, and were terrible in the wet from about 5-7k onward. I got BFG to give me a 40% discount on a new set under their warranty, or else I would have gone with another tire.

I have 22,500 on mine so far with plenty of tread left, no issues in the rain other than taking off but that’s the trade off having a truck with power

I was just driving the speed limit 40-45 in a light rain on a typical paved 2 lane backroad. Entered a turn, thank God no one was coming, but within a split second I was pointing the opposite direction

a few weeks later same thing. Rain, normal driving, entered turn and rear end broke loose and came around on me like I was on ice. But it was 80 and mid July

In West VA, you can’t rule out road contamination as a contributing factor. All the 4a in the world isn’t going to help you in a corner when you bankrupt the lateral grip bank account. slow in, fast out. fast in, spin out.

It’s very possible to heat cycle the grip right out of tire, long before the tread is gone. I’ve done it with 2 sets of motorcycle street tires and definitely lost quite a bit of grip out of some low profile car tires before the tread was gone.

What I don't like about KO2s is their ability (lack of) to channel deep water from heavy rain

I don’t disagree. The KO2 C is a speck tire designed to give good ride and reasonable off road capability. It’s not a mud tire, it’s not a road/rain tire, but it is one that you can take off road, air down, go do really knucklehead things on, finish, air up and drive home.

I’m pushing 39k on the OE tires, and this includes a good many road trips and highway miles, some off roading, but not any real Hooliganism. I drive briskly, not slowly, and for the first 20, maybe 24k was very close to factory psi. 37-38 front, 36-37 rear. Like others have posted on here, my centers have worn much faster than my edges. Also, a few others have noted the front inside tread blocks; every other one is more worn. <-- me too.

I have measurements on the tread left somewhere but not handy. If I had a winter to contend with, these tires would be gone already, but as I am unlikely to encounter snow in the near future, I’ll ride these fairly well shagged KO2’s a little longer.

I live in the PNW with rain and wet roads 6 mo a year. Drove the stock KO's aprox 50,000, and replaced with Duratracs. Big difference. Stock KO2's on a raptor totally suck if you drive much in the rain.
