I have owned several sets of BFG All Terrain tires over the years and was excited when I saw this new design, especially the side wall tread design. Unfortunately, I am extremely disappointed with the tread life. After 20 K, I am left with very low tread life, and not at all what I need for an all terrain tire. When newer, they were great in snow and light mud applications. Don't know if I got a bad set or what. I purchased them as soon as my dealer could get them after release. The Duramax I put them on is heavier then a lot of vehicles, but there was no warning against that and they should be good for a 3/4 ton truck. Won't be buying again

My first set were the original ATs that came on a '90 Bronco I bought at my first duty base near Fairbanks, AK. They never let me down even in the nastiest of tundra muck. Next set, AT KOs, went on an '02 V8 Explorer the wife and I bought our last year in Alaska that we used to haul a 10k lb trailer to South Dakota in the middle of December. They gripped and pulled up some pretty good snow-covered inclines even with all that weight behind us. Put 80k miles on that set before we traded the Explorer for an '07 Expedition with some Rugged Trails on it. Traded that for a '11 F150 with a set of KO2s on it. Those lasted nearly 50K over some seriously nasty terrain chasing elk in New Mexico. Currently in a '14 F250 that came with a set of NITTOs that were absolute garbage in the mud. Went with another set of KO2s and nearly 10k on them so far with minimal signs of wear and they go through mud like it's merely wet pavement. For those commenters that buy tires based on looks over performance, I'll be the guy that points and laughs when your stuck on the trail or replacing those "pretty" tires after just 40k miles. Pretty won't always get you home.

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.

I have purchased at least 10 sets of these tires going back to before they were called KO2's. In the 70's I met a guy with a Suburban towing a Baja Racer on a trailer. All the tires, even the trailer had All Terrain BFG's. He said he had been racing Baja for years and never had a flat! I never had a flat and get at least 45,000 miles on my tires on Astro Vans and Sprinter Vans. Hit a log in my truck w/ KO2's going about 25 mph with a heavy shock and waited for the tire pressure light to go on. No damage to tire! Don't believe the negative reviews as these tires are great and I would not want anything else off road or on!

Have had these on a 2011 Jeep Liberty 4x4, a 2013 Jeep Wrangler Sahara and now putting them on my 2016 Chevy Tahoe LTZ 4x4. Great treadwear, quiet off road tire, high quality, never a flat, sidewall or tread. Ran them in Texas running cattle and now in NW Arkansas mountains in all kinds of weather. Love these tires!

I bought the Ko2 tire the year it was released in Canada, October 2014 and have them on a RAM 1500 4X4. I wanted a AT tire I could run all year but needed the winter snowfake rating for legal reasons due to highway travel to Cariboo region of BC. I've been pretty happy with them overall. I've rotated them every 5000 km and they have worn pretty even, with only about 45,000 km on them now. I have used them in some pretty heavy snow conditions, and happy with performance, though not as good obviously as a dedicated winter tire. My off-roading has been pretty mild, mostly logging roads, a few rough goat tracks, a little bit of mud. Handled everything thrown at them, though I am not as hard on them as some may be. They make more noise than the original OEM tire on my RAM, and the fuel efficiency went down a bit, but not too bad in either respect and it is to be expected from a more aggressive tread. I've noticed quite a few bad reviews on this site, but my experience has been good, and I have noticed a few of the bad reviews state that the users have been using these tires for many years, some back in 2010. I think these reviews are confusing the regular T/A KO with the KO2's as to the best of my knowledge the KO2's were released in 2014 when I first bought mine. All said I would buy these tires again and would recommend them to others. When it comes time for replacement it will either be more KO2's or maybe Wrangler Duratracs due to my need for the winter snowflake.

Have a new set on my Ford Excursion after the old ones were 13 year old and still had plenty of tread after 40,000 miles. The old ones still looked great after the mileage. Just bought another set today for my F-150 before winter roles in. They produce a little more road noise than convential tires but you will really enjoy them in the winter.

I have had 2 sets of AT's and 2 sets of AT KO's. I've gotten 80000 miles plus out of each set with rotation every 6000 miles. According to the reviews I'm reading thatpeople are only getting around 50000 miles out of the KO2. That is concerning. What changed. If the tire ha changed that much I would have to look for something else. It's a shame to ruin a tire that has had a proven track record for over 40 years.

I am very dissapointed by the LACK of KO2 performance. The KO would last around 40k driving miles. I purchased my first and last set of KO2 on April 01 2016 ( no not an April fools joke) and yes the jokes on me. Truck had 31,458 miles on the truck. As of today 1 year 2 months later an a whopping 12,300 miles later I am being told that my tires are nearly work and need to be replaced. I am VERY dissapointed. Don't be a fool buy a different tire. No I don't off road. I live in a snowy area and I only tow light loads a few times a year. These tires simply do NOT perform!!!!!

18,000 miles on tires and have had them road force balanced 4 times!!! I have rotated about every 3,000 miles due to them being out of balance and a shimmy at highway speeds. Each time I take them to my dealer they tell me they were way out of balance again. I have not had these tires off road, all my driving is in-town and highway. The shimmy at highway speeds are Still there and not fixed, add that to the fact that they are 75% worn I am very disappointed. In the market for new tires anyone have recommendations? The tires look good but the tread wear and balance issues outweigh the looks. I would def not recommend these to anyone.
