Jeep Gladiator got a fresh set of 35s

Have been riding on BFG all terrains and muds for my 3 jeeps and dodge truck for at least the last 10 years. Never had a complaint, easy decision to go with KM3s for this purchase!

Bought BF Goodrich tires again

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.

Not as advertised

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.

All around great tire

I have these ties on my '18 Ram 1500 EcoDiesel in 12.5x33R17. I've had these tires for a year now and put 32,000 miles on them. I've driven them on every type of terrain from hard-ball pavement (wet and dry), mud, snow, ice, gravel and everything in between. These tires have tackled everything beautifully and do especially well in mud and fresh snow (kind of a given). On ice they're great, but slide a bit. On the road they are more quiet than other mud terrains, but of course have some tire whine. The wear rate on these tires is outstanding! Like I said, I have 32k miles on these and they're still at about 50% tread left. Fuel mileage dropped significantly (26.8 mi/gal freeway down to 22.1 mi/gal) but that's too be expected. I would recommend these tires to anyone.

265 Km3 on tacoma

I have had this tires just over a year. They were awesome. Great in mud, rock, the road. Snow they are great in fresh snow on trails not so much on the road. After 25,000 the story change. My truck is always shaking now there load. I’ve had to rotate them and balance 4 times in 6months. I am definitely going back to the KO2

Came from KO2's

I've had these for about 10,000 miles now and they still look new. I came from 285/70/17 KO2's in E load range on my 4Runner, and I've got the same size and also E load of these now. I had the KO2's for 60,000 miles and would absolutely recommend those to anyone who is on the fence about them. But, for what I use my vehicle for, I decided to try mud terrains on my daily driver. I was very anxious about that, and oh man. These tires are perfect. They ride smoother than my previous tires, and somehow my road noise is a bit less also. They are fantastic on road, but off road is a night and day difference. I absolutely love these tires. I would 100% recommend.
