Mud-Terrain T/A KM3 TIRE REVIEW

Over 5 years and 40k+ miles!!!!

Bought a set of the KM3s when they first came out. I had the first Land Rover Discovery 2 on KM3s in the USA. 5 1/2 years and 40k miles of wheeling from the swamps of Florida and everywhere else on the East Coast, they are ready to be replaced. No dry rotting, plenty of tread left, they have just worn a little funny (to be expected in a mud tire) and have gotten quite noisy. What am I replacing then with??? KM3s of course!!!! Best tire I've ever owned!!!

Best on the market

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!

Great tire, but pretty expensive now.

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.

Quality????

Before these km3s, I had 33” km2. I drove them about 30,000 miles and they were still in normal condition. I drive my rig everywhere, snow, rocks, mountains, swamps and sand. On my old km2 , there was uniform tread wear everywhere . But the time came and I decided to switch to 35“ wheels. I've been choosing which wheels to put on for a long time. I really liked the km2, but they are no longer being released and I decided to try the new km3. I assumed that this is the same as km2, but even better. As a result, I bought a kit and installed new tires after I made the bodilift. I drove on new tires for about 3-4 months. Everything is fine on the highway, they are not very noisy. It also seemed to me that the new tires are already old km2, although both have a width of 12.50. Now I live in California and apart from stones and sand, I haven't tried anything. These tires drive normally on the rocks. But as soon as you get stuck in the sand and even after a slight slip of the wheels, the rubber begins to crumble. A very large wear of rubber begins and right before your eyes you can see that the tread is getting smaller. Also, the tread begins to fall off. I don't understand what kind of rubber quality it is. I used to do the same with km2 and this did not happen. I don't have a very powerful truck and the smoke from the wheels is not coming at this moment. I was just trying to drive through the sand uphill. But the way these tires are falling apart stops me. And I do not know how long these tires will last me. Maybe another 3-4 expeditions?!? That's terrible. I will have to buy another set of tires soon, but it will be a different brand.

Feels Quite a Bit Different from the KM2s

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.

I'll never buy anything else

went with some Open Country all terrains and had the worst grip in just rain. Went with these and it's a world of difference!!! I absolutely love these tires. They may be a little louder but They handle extremely well in the snow and rain! all together a great tire that has lasted me years and years on one set!

Good tires on the hwy and off road on my daully. I like them

Worst on winter driving with snow and wear

Good in mud and loose soil. Terrible in snow and always get irregular wear well before the tread is used up, even with frequent rotation and alignments. These wear my second set and I will not be purchasing a third set and going with a competitive tire company.

Great tires, undersized, over priced

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

Siped they are great for Winter and Summer in Alaska.

I have been running these 37x12.5r17 on my 2 door wrangler custom siped in the center 8” of tread as both a daily driver and trail riding both winter and summer here in interior Alaska. They wear faster than the K02’s, but aired down to 25psi they work exceptionally well on hardpack snow and ice, through 2 feet of snow in winter, and medium mud loads in summer. And they don’t clog up in the deeper stuff (snow or mud) like the K02’s do.
