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 bought a set of 4 35x12.5x15 km2's in 2010. The truck sat for 4 for the last 12 years but easily over 60k miles hardball driving and 10k miles off roading or mudding and i still have ¾" worth of tread. Upgrading to km3's soon and hear they are better than the km2's. Extremely happy with this tire design. Lasts forever

I bought my set of 35x12.5x15 km3 a little over 3 years ago, I’ve owned my Jeep for over 28 years by far the best tire ever . It makes the Jeep ride smoother for sure. I’ve been off road in light and rough terrain and they perform excellent. I would recommend these tires to anyone looking for great ride and great grip. BF Goodrich did their homework and research when they came up with the Km3. CUSTOMER FOR LIFE. OIIIIO

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 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.

I bought a set of the km3 and was excited . Ive always been a BFG fan ever sense the bfg km mt . Then the km2 came out and they worked amazing on road and off road and got lots of millage out of them and sore by if you wanted a radial mt tire the bfg km2 was the best for all purpose . Then when the km3 came out i got a set and honestly i was crushed by the performance . Sure highway road stuff they where fine . And gravel roads . But life span was stupid short and off road performance sucked . Mud not good . Slick stuff like clay and mushy snow not good . Sure in moderate rocks they worked but then a again a bald tire works for that as well . Needless to say i was disappointed in the km3 . My km2 i got 66,000 miles out of and the km3 i got maybe 20,000 out of them . These where both ran on the same truck . Ive also ran them on other trucks in my fleet as well ( personal fleet ) bring back the km2 and ill by them for every thing i own again also would be nice to get 39 kx back in blue label best rock tire the every day weekend warrior

We replaced our aging K02's in Oaxaca, Mexico with a set of KM3's and they took us exploring offroad through the jungles of Central America to the great Paracas sand dunes of Peru to the Bolivian and Brazilian Amazon jungle. Had enough tread to make it back to the USA. Shocked they lasted that long on our heavily loaded Land Cruiser.

Bought two years ago, and have less than 15k miles and tires are already worn down to less than 40% life. Website advertises BFG KM3 50k/6yr warranty and when filing warranty claim advised they do not have such coverage, false advertising. Drive my truck 2-3 time per week for mountain trips/hunting/camping, no serious or egregious off roading, tires performed decent on off road trails/backroads but poor materials due to such quick wear. Inspection report advised tire bands are bad as well. Second set of BFGs, first K02 and second chance KM3, 9/10 do NOT recommend either. After calling warranty number and being placed on hold was sent to a survey after an extended period of time then call terminated.

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 bought 35x12.50r17 almost a year ago. Two tires wore out horribly and uneven. The other two are half tread or better. I installed all new suspension in shocks a month prior to installing my tires. Rotated every oil change. Was not pleased with the wear of those two tires. Have since sold them to try and make my money back for another set. I just ordered 39x13.50x17 for my truck now and they’re on indefinite back order. Really liked the look and performance, so I went with the KM3 again in a larger size. I hope these ones wear fine, and are put into production soon!
