I hade about 10k on mine, including many off-roading miles like the Rubicon and they still looked new.
They are as close to a perfect dual purpose tire as you can get, except size availability (for me 'cause they don't make 40"x17") and they are so excessively heavy. For me, the KM2's and Toyo's are the two top runners. I hear a lot of great things about the Cooper STT's and they're priced right, just no sizes for me......
As far as weight's concerned, take a look at the data I collected and notice Toyo's weight - it's a deal killer for me.
FYI - All these #'s are from the manufacturers
37x12.50x17 tire weights (a few of these are 13.50)
BFG KM2 - 71.6#
Yokohama Geolander M/T -71.6#
Goodyear MT/R w/ Kevlar - 76#
Interco TrXus M/T - 78#
Interco Irok Radial - 81#
Mickey Thompson MTZ - 83#
Pro Comp M/T - 84.4#
Toyo Open Country M/T - 92.6#
Cooper Discoverer STT - 83#
Nitto Mud Grappler - 92.8#

I'm looking for a 255/85-16 and these seem to be the winner; they'll be lighter than my MTR/k 285/75-16s that are on now and have less rolling resistance.
I'm really hoping to pick up 1 or 2 mpg in the bargain too.

I don't think the weight comparison is a fair fight. Yeah, the Toyo is heavier but it also has a nice beefy and more aggressive sidewall than the KM2.
Is it worth an extra 20 lbs per tire though? That's a huge difference in weight.

I'll give you my experience with KM2s. For the most part, after 20,000 miles I still love them. They work great in every condition I have encountered except one. Ice on the road. If you get sideways, there is no returning. They turn into ice skates and things go wrong fast.
One other issue. After balancing my tires the other day we found one that is severly out of round. Lucky for me I bought five and kept them all in rotation so it is just becoming my spare. I would say this is just dumb luck but another friend of mine just bought a used set from a guy. They still had the nubbys on them so they were pretty much new. He also had a couple that were not round.
I know this isn't enough to say it is a pattern with them but it makes me a little nervous.

I've ran BFG AT KOs, BFG KM, and the Open Country MT has been a great tire... like other have stated though, very heavy. The do wear like iron though and have been a great tire overall. We run them almost exclusively on all of the Dodge Diesel fleet vehicles and the weight isn't an issue there. On my 1st gen xterra, a much bigger deal, lol.

The sidewall lugs probably add minimum weight to the Toyo, I'm pretty sure it has more to do with the casing structure, and how many plies, as well as the density of plies in the tread and sidewall.
The Toyos and KM2's may have the same number of plies, but if the Toyos are significantly denser (more threads per square inch) then it will make the tire a lot heavier, and will also provide better puncture resistance.
That's 2 things you guys that have run them, are mentioning.
Oh, and when I'm saying "ply" regarding the actual construction of the tire, that is different than the "ply-rating" of a tire. (8-ply, 10-ply etc...)

If I get the Toyos in a 255/85-16, they'll be 4 pounds lighter than the tires I have now. And 3 cm narrower.

Some sort of lost...
My experience with the km2s on ice have been great. Even on solid 1" ice that we got last winter. But my truck is heavy and they were fairly new.
I do think one of mine may not be round. I have had a hell of a time with one of them and had it rebalanced several times. It still shakes at 45mph no matter which position it is in. I learned to live with it and forget to mention it sometimes. I believe I have heard more similar reports, which also makes me apprehensive to buy another set.
I loved the 33" Cooper stt that I had on my explorer though. The only complaint I had with them was that they were terrible on ice, but siping them would make a big difference.

Guys, if you are getting instances where your tires are out of round, ESPECIALLY when they are very new, you should really be going back to the tire dealer and get them warranteed.
If you put 15,000 miles on them, and THEN find one seems to be unbalanced, that's a different situation, and the tire dealer will suspect that there is an issue with your vehicle causing the problem, not an issue with the tire.
You really need to get this sort of thing looked at ASAP to ensure you pay little or nothing for the replacement tire.

If I may, in another thread and on a few differet boards retread tires seem to be doing well a company by the name of treadwright offers quality retreads for a fraction of new tire price. For what the original poster needs this my be worth looking into (I am) http://www.treadwright.com/shopnow/product/tabid/61/productid/55/sename/28575r16-guard-dog-mt-d.aspx

Same here, but my truck is also heavy (6,800#) and has a very long wheelbase (131"). On ice I can kick my truck to the side and drive it like a drifter, as soon as I let off the gas it will immediately straighten up.....probably a wheel base thing mostly....

I measured them mounted up off the truck and they measure exactly 37" by 12.5"
