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.

Looking on website to find out if my existing rims would suit new, wider tires. No information on website about what range of rim widths suit what tires. This is surely meant to be available SOMEWHERE, or are we meant to guess? (Australian purchaser)

I drive a 1979 Toyota Landcruiser FJ40 that I have had for 30 years, and it has always had BF Goodrich tires on it. I first put All Terrains on it at 66,000 miles and have since put a total of 3 sets of All Terrains and one set of Mud Terrains KM's on it. I just put a set of Mud Terrain KM3's on it today (at 250,000 miles) as the previous KM's have become too old. I wasn't driving it much and not paying attention to the age of the tire and realized that they were 11 years old. Not once have I ever been stranded due to a tire related problem, The only time I have to use a jack is when I rotate the tires. I have been extremely please with all the tires, but even more so with these latest KM3's. Unbelievably quiet and smooth riding, There has been a huge change since the original KM. This will probably be the last set of tires I'll put on the vehicle but my grandson will probably enjoy them since he will be the next to own it.

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 ran these on a ram 2500. Loved the tires the are quiet, handle well, and do good in the mud and even snow. However at 21000 miles they were to within 2/32 of the wearbars. I wanted to run them again but at 1600 a set I couldnt take the chance with the treadwear I experienced. They wore flat and even just extremely fast

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.

I have had these tires on my 2013 Jeep wrangler Rubicon for 20,000 miles. They are the best tires I have purchased for on and of the road performance. On road performance they have great traction is Rain and Snow. Off-road performance these tires are great under pressure and when needed. I have used the tires on countless rock crawling trips and absolutely no complaints. Not too loud cruising down the highway (70mph) for a Mud-Terrain tire.

I had these tires and after 40,000 miles they still had 20-30% tread life left. Rotations are critical with these tires i found and needed to be done at about 5000 miles. Just slightly more road noise then my KO2's were but did get louder as they got older. they worked great in all offorad contions, sand, snow, rocks. On the road they were also very good but needed a little more attention in the rain but its a M/T so expected.

I have a 21’ rzr xp, with a set of 30inch km3, it’s been on the same tires since 2022, 3 years with the same set they havnt worn bad and always have traction in the dirt , sand , and especially the street lol, they’re tough tires definitely getting another set soon

I have been running KM3's on my vintage Land-Rover, hitting tough trails deep in Death Valley for a couple years now. My drive just to get to DV is about 500 miles, and I am doing some other highway miles locally. The desert performance is great. DV is famous for shredding tires, but I have had no problems. I am stunned by the low wear on pavement. Highly recommended. Most of my L-R buddies "in the know" are running them.
