Thought I found a great tire to replace stock on 2006 GMC Sierra crew 4x4 diesel. I enjoy music so hoped they would be quieter, nope. Got louder as they wore. Near done at 27k mi. Hoped for 40- 50k, nope. Bought for traction- mud and snow, nope. Couldn't get up a long driveway in Idaho towing a loaded trailer, and didn't handle well on a couple backpack trips, so moving on. Sorry BFG.

I've only had these tires a few weeks so I am rating performance not longevity or tread life. I purchased these tires right before deer season here in Idaho. I tow a 31.5' travel trailer into the mountains. The roads were descent for the most part. The last mile before my camp they turned seriously muddy with huge puddles. With my truck in 4WD high the tires performed amazingly well. We also had packed snow on the mountain roads and they did great in those conditions as well. And they look beefy on the truck. Much better than on the store shelf.

Bought these tires 2 years ago, the tread wear is great. The sidewalls have started cracking on 3 out of the four tires purchased. One of the tires has extremely large cracks beginning in the tread area extending down onto the side walls. Looked on YouTube appears I am not the only person that has had this same issue with this same tire purchased from this same time period. Looks like the rubber gets incredibly dry for no reason and deteriorates in just a year or so. VERY Expensive tires to have sidewalls that go bad and risk the lives and safety of the persons operating the vehicle and others traveling on the same roads. Serious safety issue with tires such as these being sold to all over the United States.

They are great off roading in the southwest desert but very difficult to balance for highway speeds. I think I finally got it worked out. Long story short: go to an expert who cares, takes pride in their work, and does hunter road force balancing.i

Have them on a 2002 f250 diesel 4wd and love them. My truck has chewed up toyos in 20k, have 30k+ on these and have good tread life left tow a boat and haul often. Had original ko's before and went over 60k on them. Do well in snow and dirt, haven't gone in mud or sand so can't comment on that.

My son highly recommended these tires to me because of his history with them on his Isuzu Trooper. I put them on my Jeep Cherokee Trail-Rated Trailhawk 6 years ago. 23,000 miles on them now and I could not be more pleased with them! The tread is still almost like new. At least 10,000 of those miles have been off-pavement, and probably 2,500 miles on rough, rocky, sometimes steep backroads and trails, as I am an enthusiastic off-roader living in a central Idaho town surrounded by mountains. The traction is awesome in snow and mud, and the tougher sidewalls have been a real boon over sharp rocky trails. I have NEVER yet had a single flat!! They are also completely quiet and smooth on-highway for me. I thoroughly and enthusiastically endorse these tires! I will certainly buy them again if this set ever wears out, lol.

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.

I just bought a set of the KO2's and so far I am very pleased. They are a lot more aggressive than the original KO's. They have a little bit of road noise but you will get that with any aggressive tire. Can't wait to use them in the snow and hit a mud hole with them.

I have for past 15 years bought BFG All-Terrain tires, I switched from 18 to 20 in rims with exact new T/A KO2 tires. All my trucks have been 2500/3500 single wheel diesels. My current truck has 16,000 miles and tires are shot, slip on all surfaces, helpless in water or snow. The tires are rotated on schedule, kept to correct inflation pressures, and minimal towing and still wore faster than ANY other tire I have put on a truck. As expensive as tires are nowadays they should warranty these tires better than excuses. This is my last set.

The shop only inflated the tires to 37 psi, which appear fine, not low. Yet the psi on the tire is 80!!! I have a 2014 Chevy Silverado. The standard psi is 37, but they'll wear out way too fast! So I contacted BF rep online and they suggested 50. I may go 60... But just a heads up... Be aware of the pressure issue, and how it pertains to your specific vehicle.
