First post, just thought I would share some info about the new KO2s as I was not able to find much anywhere about off road performance in tough conditions besides the BFG sponsored Baja "test".
I just put on around 450 miles off road (much of it extremely tough off road) and 1600 highway in CO, UT and AZ over the last 10 days. Everything from deep snow to heavy mud to rock crawling to hard pack snow/ice to fast 60mph desert running (I also just added Icon suspension so I was running a little faster then was smart at times).
I've had two sets of the old KOs on an FJ and a 3rd gen 4runner before that. I'm a long, long way from being an expert on tires, but I am a pro outdoor photographer so I live outdoors and spend insane amounts of time off road. I also grew up on a farm in CO winters so I have quite a bit of experience off road with many 4x4 pickup and tire combos (mostly M/Ts). Again, far from a tire expert, but I wanted to help anyone struggling with the decision to go with these or not. I was considering the Toyo A/T or the the Duratracs before these came out but hated the weight of the Toyo's and the 2 ply sidewall of the Duratracs even with the E rating. KO2 maybe the best of both??
Overall so far: Excellent!
Highway: Very Good (plenty of info about this online)
Packed Snow and Ice: Excellent! (I am really, really happy here. Tested on a steep mountain road with tons of curves. Hard to find worse {or better} conditions for a test. Really impressive and hands down better then the KOs)
Deep(ish) Snow (1ft): Very Good to Excellent (need more time in deeper snow to really tell, but in about 10 miles of 1ft deep and 20 miles of 8in deep {three day old hard packed, which is always the worst} and a decent incline I had zero issues in 4low finding traction)
Heavy Mud: Good (I am very happy for A/Ts and compared to the KOs. Still not Great clean out of course, but very accecptable for what they are)
Slick Mud: Very Good (in the lighter slick stuff they did really well and I was very impressed)
Rock Crawling: Very Good to Excellent (tough to tell here what amount of traction was due to the tires vs the better suspension keeping the tires on the ground more often, but I had a TON of traction. I saw two guys having hell getting up Bobby's Hole (one Jeep, one heavily modified Xterra). Sliding and jumping and multiple attempts. I just walked right up it. Partly (mostly maybe) due to rear def lock and A Track helping out, but I had both on the FJ and def lock on the 3rd gen and would have had more trouble with either getting up Bobby's (between the tires and suspension I am extremely happy with the crawling ability of the 5gen Trail)
Durability Off Road so far: Very Good (I know only 450 miles off road doesn't mean much, but considering the speed and that most of the miles were on terrible rocky roads it did give me some idea what to expect. There was definite chipping on the tread but not as much as I expected. I can't compare to the KOs because I have never had suspension that let me run stupid fast on such bad roads. I was honestly planning on needing the spare and possibly repair kit, but had no issues. Sidewalls held up great. Very happy so far.
