Purchased a set of 4 KO2's 4 1/2 years ago for my 2003 Silverado Z71 1/2 ton LB. Extremely pleased with the traction in rain and snow. However tread wear looks to be an issue. Currently have 34k on these tires. I will be lucky to get another 10k. I am religious about checking pressure and rotate every 6k miles. Was expecting to get at least 50k out of these. Would like to buy another set of KO2s but undecided at this point.

Tread life span is horrible! Only lasted me 40k - hauled a small utility trailer 5% of the time and rotated religiously! Also picks up every size rock there is on a dirt road and kicks up to cause a ton of rock chips even with splash guards in place

I've had several sets of these tires on a number of vehicles including Jeeps and Toyota Tacomas. Every few years when they finally wear out, I research the market thoroughly for the best tire that can handle both tough off road jeep trails and provide a quiet, solid drive on a highway and I inevitably return to KO2's. Yes, you can find better rock crawling tires and yes, you can find better street tires, but you can't find better tires that will be 9/10 in both. Over the years, I bought a couple alternatives, none came close. If you spend 80% of your time on street/highway, but still need aggressive tires for the desert and mountain trails, this is the tire you want.

I've run a number of tires and these are by far my favorite AT tire. They ride great on the road and provide more than adequate off-road performance. No problems with the E rated 35x12.50R17 on the 2015 Jeep Wrangler Unlimited Rubicon. Smooth ride. After around 15k miles and regular 5-tire rotation, the tread is going strong.

I been buying bf goodrich for a long long time, mid 1980's. The all-terrain on a seperate set of rims and bf goodrich TRUCK TA for non winter months back around 1986. (since mergers, Truck T/A no longer available) I wanted the solid white letters and selection as I recall was BF Goodrich only. Also my muscle car also had T/A on it. Anyways I have close to 40,000 on the ko2 and they are at 3/32, very noisy, dispite 5000 mile rotation and no uneven wear. How I see other comments stating many more miles on them is confusing to me. Anywhy, since the mid 1980's I think a change in choice is coming. Every time I bought a new 4-wheel vehicle, i worked with the dealer to get the tires swapped out for the bf goodrich. Not satisified.

I have always have run TA KO's on my Jeeps for over 35 years. Currently on my '75 CJ5 and original owner '78 CJ7. Put the KO2's on my 4Runner. Could not be more pleased. Currently have 30k miles on them and had 11/32' at service. They are great tires off-road, rain, snow, and mud. They perform excellent on everything so far. It's all about tire pressure and your driving ability/habits.

I like them at least as much as I liked the KO. Very good in dirt, rock, rain and snow. Decent mud traction for not being a mud tire. Quiet on-road with good handling. Much better on-road than other offroad tires I've had while maintaining excellent grip and control off the pavement. I'll need more miles on them to see how they wear long-term but so far, so good. As far as people complaining about them not being mud tires- right...they are offroad tires not mud tires. If you plan on mudding get mud tires but expect a lot more drawbacks than the KO2's have. I would buy them again. I'm a lot more confident with them offroad because that's what they are designed to do and I can feel the difference between them and a road tire.

Bought them last fall for my overlanding rig, ran them hard for over a year now & put ~20,000 miles on them. I will likely re-buy another set in 285/70R17 (C-rated) once tread runs out on the current set. Overall very happy and confused why a lot of people in the community keep thrashing this tire ... the below is fully based on my own experiences, I do not claim to be an off-road expert nor did I have a lot of comparisons with other truck tires. I paid for my tires. PROs: + Ability off-road ... I have been throwing rock gardens/shelves, deep sand, muddy forest roads, desert roads, deep snow at these tires and never had any traction issues off-road. If other tires are even better I haven't been in a situation (yet) where that would've mattered ... the areas where I feel they excelled at (even vs. other off-roaders I met on the trails) were: (1) deep snow and (2) deep sand - others got stuck and we didn't + Quiet on the highway, light, didn't affect fuel consumption much (~1 mpg) when I switched from the stock tires in 255/75R16 to 265/70R17 KOs (they are the lightest tire in this class ... which is noticeable in terms of performance, breaking, MPGs) + Even wear & durable: 20,000 miles, rotation every 5,000 miles, balancing after 15,000 miles - still enough tread for another 20-30k + Looks: Subjective but I like them over a lot of other A/T tires CONs: - Tendency to hydroplane in wet conditions - scary, but manageable - Traction on packed snow or ice is not great - didn't run into these conditions off-road but on regular streets in the winter I got into some sketchy situations - They wander a bit when changing lanes at higher speeds (>75mph) ... but that's to be expected when getting C-rated tire on a ~6,000lbs rig (fully loaded) Some other thoughts: > C-rated over E-rated tire all day ... been pushing them aired down on sharp rocks and haven't had any flats or cracks in the tire > the weight does matter ... especially on our somewhat underpowered Tacomas (even with re-gear) ... it's nice to have a bit of extra punch vs. some other A/T tires that are 20% heavier > In dry / sandy states these tires are really hard to beat. In some rainier / wetter states like Washington there are other tires that perform better in wet conditions ... but so far not enough to change my mind ;)

I have had these tires for just over 1 month and we have had 19 out of 27 days of below 0 and snowing weather and these tires have been amazing. I have a 2011 F150 and this is my 4th set of tires and hands down the best Snow and Ice tire I have had yet.

Bought these for my suburban years ago. This is more than likely the best large tire on the market. Mine finally started to dry rot last year & split on the sidewall. Only problem is they changed the design.& now I have 3 old design.& 1 new design so now I'm stuck buying 3 tires instead of 1 but like the new design better anyway. Worth every penny.
