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.

Love the tire off road, performs excellent and absorbs a lot of shock and impact. They are heavier and mileage has decreased. I’ve had them since 2019 and have put @ 15k miles on them. Still holding at 70% tread life. Rotate every oil change. Here’s the kicker; they are squirrelly on the freeway and like to wander the lane. They can be a bit wishy washy if you have to abruptly lift off the throttle. I’ve put BFG on all my cars and trucks for near 20 years and always will. I think when these go, I’ll back down to the AT’s. Lastly, I did buy a fifth spare MT so I’ll be offloading a new MT to swap to AT’s. Love the tire, off road they are king, on road you need to be ready to provide extra driver input.

I agree with the user above the tires are great and you hit about 20,000 miles I purchased 10/2019 And just replaced got them at 31k miles just replaced at 60k with lots of tread left. The more miles you get the more wobbly kids and shaky it made me think my limit was off or something else was wrong now tired or replace not a single issue alignment was fine. It felt like the tires were going to shake off..

The best M/T tire on the market! I have run quite a few other manufacturers M/T tire and so far this is the best out of all of them! These are replacing Nitto trail grappler and for people saying that B.F.G tires are cut small, once I had these mounted and under weight of my Jeep they measured the same. On the road the KM3 handles better then the competition and on the trail they do a amazing job! Even on wet roads they hold traction way more then other M/T tires. I am definitely going to keep running B.F.G tires from now on!

I put a set of KM2s on my 08 Tundra a few years after I bought it and they were expensive but I believe they are the best quality mud tire on the market. They are a little noisy and they don’t do great on pavement but they are outstanding when you get in the mud and the way they make your truck look is just worth it IMO. After the KM2s eventually wore down after about 50k miles I went ahead and got some KM3s and they look even better than the 2s and I feel like they are a little quieter on the highway. Not to mention the 2 sets and over 100k miles over all kinds of misquite thorns and road debris, I’ve never had a leak in any of my BFGs so far. I can’t say the same about the Michelins on my Camry or the Goodyears on my Tacoma. And don’t settle for the cheaper Taiwan made Nittos either.

I purchased a set of 35" BFG Mud Terrains a few years back for the first time and loved them. When I was ready to move up to 37's they were out of stock. So, I purchased a set of Discovery SST Coopers in 37". Good tire but I sold them as I felt that they couldn't compete with my KM3. SO now my FJ Cruiser and JK Rubicon are both sitting on KM3 tires. These are great for the daily drive and excellent on the rocks. My JK will now move up to 39" KM3s as soon as these 37's wear down and my dana 60’s get built. Needless to say this will no longer be a daily driver. Unfortunately, this isn't happening fast enough. But I absolutely love these, and I think highly recommend them without a doubt.

Had KM 2' on 3 trucks....love them. Bought a new trucks k in 2016 and immediately looked for a set of KM's. That year, the KM3 was new,purchased and installed. 7 years and 103,000 miles later looking for another set. This set still has miles left on them. Just time. Rotated every 5k and balanced every 15k or so. Never been let down in some of nastiest stuff the swamps of maryland can dish out.

I am really blown away by these I always heard M/T tires are loud, nope not these pretty quiet even for a jeep. Love the performance, the durability and hope it lasts as long as mine A/T tires did. All I need now is a matching spare. I have these mounted on 15inch and can easily air down to 12psi without worrying about breaking a bead. These rode so nice I would recommend these tires to everyone, especially if you have a Jeep the road noise is almost non existent. And man these look great also.

I used to have K2s before I got my 285X70R17 KM3s. Here are some differenced I have observed: The KM's are noticeable wider than the KM2s. I did not measure the width of my KM2s, but I had to cut the stops on the tailgate for the spare tire on my Jeep JK by about 3/8" for the tire to fit onto the spare tire holder. So I would say the KM3s I have are about 3/4" wider on the sidewall than the same size KM2s I replaced. This is not a complaint - I just thought I would share my observation. The KM3s feel "squishy" compared to the KM2s. I am running them at the same 37 psi as the KM2s. The "squishy" feeling is very noticeable on turns and the Jeep rolls much more than it used to. The steering response also seems to be diminished. When I make a sharp turn, there is a very brief, but noticeable delay in the vehicle responding, and when it does, it feels like it is grabs. The KM3s have a different noise than the KM2s. The KM3s have a higher pitched hum than the KM2s. This higher pitched hum is mildly annoying. I have read that the tires get noisier over time. Hopefully, the noise will not increase too much. I realize these tires are more intended for off-road use as opposed to highway or city driving. I have not tried them on the trail yet.
