I've got about 4K on my set and have no complaints. My size only came in an E rate so they are a tad stiffer but still ride great.

I got mine last week, also from Discount Tire Direct - 35x12.5x15 on 15x8 Level 8s. I am pleasantly surprised how smooth and quiet they are for a mud tire. I've not tried them out off road, but they're terrific on road!

KM2's are end of life? BFG is supposedly working on the KM3, so pricing is going way up on km2's. (at least that's what I found when looking at 37's.)

My local discount tire had a set of 37x13.50x18 STT Pro's sitting there, so I did a quick side-by-side comparison with my 37" Falkens.

Cooper Discoverer STT Pro - 37x13.50x18
(mfg spec 36.77 x 13.3 , unmounted appx 36.60")

Falken Rocky Mountain - 325/80/16
(mfg spec 36.3 x 13.1 , mounted spare 36.50" , front tire 35.50")

Picked up a set of 37x12.50x17 STT Pro's & MB11 rims

Added a road-trip:
Just finished a 17-hour drive on the 37" STT Pro's, and thought they handled fine. I was towing an 18' ski boat, with a ton of crap stuffed everywhere in both the jeep and boat, so wish my crappy 3.8 had a LOT more power, but no problems with the tires. They seem to have balanced well, they give a good ride, and no 'radial pull' which is talked about further down in this thread,

Even pumped up to 40 psi for the trip to handle all the weight, they did not feel as stiff as the previous falkens were at 28psi.

Possibly worth noting, the STT Pro's were noticeably louder when pumped up to 40 psi, no clue why that was.

Just to get some info on the 37's out there:

Current tires are:
Falken Rocky Mountain - 325/80/16
(mfg spec 36.3 x 13.1 , mounted spare 36.50" , front tire 35.50")

Cooper Discoverer STT Pro - 37x13.50x18
(mfg spec 36.77 x 13.3 , unmounted appx 36.60")

The STT's look quite a bit bigger, even though the specs are very similar...

I like those. ...looks very similar to the duratrac pattern.
