I have had these tires for over six months and put a considerable amount of miles on them in six months, between driving a lot of highway miles and a lot of off-road miles they hold up. all of my wheeling buddies run other competitive MT tires and none of them grip up nearly as well, I have used them in snow, mud, dirt, and slick rock, and I have not been impressed by the competition. KM3 is my go to tire for sure. also surprisingly quite at highspeed and around town.

I had bfg ko2's and decided to get some mud terrains and went with the KM3. I am happy that I did because these tires perform better off road and look cooler too. These perform well on the street and in the rain. I used to put my truck in 4wd sometimes when it would rain a lot and the streets would get flooded but with the mud terrain km3's I don't have to. I have had these tires for about 18k miles, used mostly on the road, and they still look awesome and have plenty of life left on them.

I bought these KM3’s 2 months ago. So far they have been in the snowy mountains, icy pavement, heavy rain downpours on the highway, deep mud, and just recently sand. I have ran them at 50 psi with no sway and they absorb bumps well at speed. After 5k miles I project them to reach 65k miles... but that is a very very early projection. Anything over 50k miles and there is no competition in the mud terrain tire category.

I bought these for my 2017 Colorado ZR2 in 285/70/17 (E load) when they first came out in June of 2018. Overall, I got 66,000 miles out of them. They could have gone another 5k miles or so, but I believe I potentially got a slightly defective tire, as it has worn unevenly and is not perfectly round. Thus, there is now too much vibration to continue driving on this set. The other three tires in the set have worn and performed perfectly. The worst of the tires is pictured below. I always rotated the tires during oil changes. However, I elected to live with the “bad” tire and it was fine. It only became a problem in the last month due to the vibrations in the cab and steering wheel because of the imperfect shape. This was a very early set of KM3s so I’m not upset or surprised by this, as I think it is bound to happen. I took these tires to MOAB and on other off-road trails and they were very tough and had great traction. I’m giving 4 stars because the on-road ride quality leaves a bit to be desired, between the noise and vibration I experienced. I have since moved from CA to CO and need better snow traction. So I swapped out the KM3s for KO2s. Sticking with BFGoodrich!!! Don’t let my story stray you from these tires. Overall, they were awesome! I just have different needs now. I would also recommend a C load rating if you drive a smaller vehicle like mine. The E was a bit stiff for my truck (running at 38 psi).

I've always had BFGoodrich All-Terrain tires and have always been very pleased but I decided to give the new KM3 a try. I couldn't be any more pleased! These are by far the quietest and best riding mud tires I've ever had heard or rode with. Once in Montana I drove my truck through many different conditions ranging from sticky mud, slick mud, Ice and snow. I honestly put myself in a few predicaments that I shouldn't have and every time these tires made up for my questionable decisions. BFGoodrich has set the bar pretty high with this new tire and I probably owe them dinner for getting my truck back home.

Bought a set of 4 km3's, and the front left wore bald and nobby...had truck balanced and aligned, the day they were put on..had it checked out again to make sure nothing with suspension broken...nope..so now I'm buying another tire...and obviously it won't have same wear as my others...and I don't like that..

I bought a full set of 5 for my Rubicon. I went with the LT315/70R17/ E 121Q tires. I wanted 35 inch tires and the Goodrich website stated these tires at 34.4 inches. I thought that was close enough. Got my tires and drove them for a bit and then thought I would just check the tire height. Imagine my surprise when I measure them fully inflated (37psi) at 33.0 inches even. Not even close to the 34.4 stated on the website. Love the tires, but wanted the tire height.

I've ran the 39x13.5r17 KM3s for 2+ years and over 40k miles on my Jeep Gladiator. I've put these tires through all kinds of terrains and weather conditions from dirt, sand, rock crawling, mud, rain, hail, rock crawling in thunder storms and they haven't let me down. I keep rotate them every 3k to 5k miles and they have worn evenly. The side walls have been holding up great and the side bitters have provided plenty of traction when needed. The light weight of the tires is also a plus. My only gripe is these tires have gotten fairly expensive since I purchased them in 2021. The price has increased roughly by about $250 per tire. They are almosted priced near the cost of some 42s. Well known competitors 40s don't even cost as much as these 39s. With that being said it opens the door to try some of the top competitor's tires for about $200 less per tire. These 39s compared to most 40s make the 39s look like 37s because of the actual size.

I have had the mud snow tires (31x12 x15) on my 1989 Sidekick and love them. They air down to 12PSI and take me where ever I need or want to go. They grip well off road on rocks but I try to not drive on the sidewalls, yes they are thinner but that makes them flex and grip well. Even in snow and ice they grip and handle better than any other tires that I have tried. I am getting a Jeep Rubicon and these will be one of the first things that get installed.

I’ve tried just about every off-road, AT, MT tire made over the years. I keep coming back to BFG for the quality tire that they are. Currently running the KM3’s on my Jeep Gladiator. These tires work great on road and are exceptional Offroad. The two main complaints I have, which is pretty standard on all BFG truck tires. Undersized for what size they advertise them to be. And I’m not talking about just a little bit. BFG’s are some of the worst about under sizing. ALOT. Once you get to the really tall tires, the prices are outrageous compared to their competitors. I’m in need for a larger size now and the BFG price is outrageous on 39’s (which are actually 37.75” tall supposedly) sorry BFG’s looks like I’m gonna have to go to your competitor after all these years
