I had the KO2's put on in November of 2014 on my Chevy Silverado 1500 Z71and they are the best tire I have ever had! The track fantastic in the mud and snow. I have only had to put my truck into 4 wheel drive a couple of times all winter compared to last winter where i was in 4 wheel drive with more expensive tires pretty much all the time. If you need new tires I recommend putting these on your vehicle. You will not be disappointed.

I bought these tires and had them installed last week 20" for a 2500HD. After installation I noticed a very soft spongy ride at low speeds. At Highway speeds my truck sways and has lost a lot of the steering response. I hooked up my travel trailer about 5500lbs and the trailer now controls the vehicle with all the sway in the tires. I called the dealer where I bought them and they told me, sorry. I would not recommend for a heavy truck or for heavy towing if you call 5500lbs heavy. Not satisfied at all. Will have to drive the truck less because of this.

Better than the Ko1 design as far as the side wall. Not better in performance. For snow I prefer the Mud terrain over this tire. AT fills with snow/mud and does not clear it out like the MT does. If you do mostly street driving this is a good tire, If you do any type of winter driving, mild off-roading or aggressive off-roading just scratch the AT off the list and buy a different tire. Will not buy the All Terrain again...

Bought these all-season tires for my 2018 Silverado 2500HD. Love them when they are new. After 30k miles they tend to be much louder and noticeably start to lose their traction 6/32"-7/32" tread depth left. These replaced Duratracs (more mud terrain oriented and not an A/S tire) which were howlers after 30k and not severe winter rated for LT275/65R18E sized tires. These tires are much better in the wet, dry, snow and for summer towing duties called upon it to do. I don't need a more aggressive (M/T) tire since I never take it in conditions that call for it. When you get to 5/32 start looking for replacements if you drive in wet or snowy weather.

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.

I love the new look of the all terrain ko2. I have purchased the AT's before and now I am hooked all over again because of the great looking side wall that beefs up the look of my truck. The AT's still have the proven tread pattern that is a great performer on wet, dry, and muddy surfaces.

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 ;)

Have had these tires on for 3 months now. Driven through standing water and 12" of snow here in Michigan. These tires go through everything! I don't drive too fast, but took these tires up to 85 mph just to test, without any issues. I feel more road at low speeds with a slight increase in noise. And so far, that's the only "down side" which I consider negligible. Above 30 mph they feel like, sound like any other quality highway tire. Love the way they look! Can't wait for a 18" snow dump just so I can go drive around again.

Loved these tires until now. I am finishing my 4th set of these tires, or 3 sets of KOs and 1st of KO2s. I absolutely loved the KOs. Not one single thing to complain about. Averaged 50k miles on all 3 sets. Was so happy that for the 4th set I went with the "improved" KO2s. I am now through this set and have only 27k miles on them. Great tires, just like the KOs, but mileage is no where close to what it used to be.

Purchased (5) 35x12.50r17 KO2s and immediately had a vibration at speed. 600 miles and 4 balance jobs later, the tires will not properly balance. Tires have been broken and spun on wheels to no avail. Severely disappointed at this point, these tires are pricey. I didn't read review beforehand, as BFG has a great reputation and I've been through 3 sets of the original KOs, however, it appears I'm one of many people to have this problem. I've submitted a warranty claim and will update this review pending the result.
