The BFGoodrich Mud-Terrain T/A KM2 (KM for Key feature: Mud traction and 2 identifying it as BFGoodrich’s 2nd generation KM tire) is an Off-Road Maximum Traction tire developed for off-roaders driving full-sized, lifted trucks that participate in rock climbing and/or other challenging off-road driving.
The Mud-Terrain T/A KM2 is designed from the mud up to overcome almost any obstacle in its path by combining more traction and mud-clearing ability than its predecessor with a smoother ride and less road noise than normally expected from an aggressive tire.
The Mud-Terrain T/A KM2 molds an off-road tread compound into a Krawler T/A KX-inspired symmetric design that features deep, self-cleaning independent tread blocks and linear transverse flex zones that provide the elasticity needed to allow the tire to conform to off-road obstacles when aired-down and driven at low speeds.
The tire’s internal structure includes twin steel belts and BFGoodrich’s Krawler TEK sidewalls and casing. Krawler TEK consists of three components that include aggressive sidewall lugs, cut- and chip-resistant sidewall compounds and BFGoodrich’s TriGard casing (three-ply polyester construction) with sidewall cords that are up to 33 percent stronger than the previous Mud-Terrain T/A KM tire.
These advancements allow for more bite and sidewall protection along with increased strength and resistance to bruising caused by rocks and rough trails. Single strand beads (a single strand of bead wire is continuously wrapped multiple times until the desired strength is provided) enhance the tire’s fit to the wheel to improve uniformity and ride quality.
While Off-Road Maximum Traction tires, which are often called mud tires, are branded with the M+S symbol and able to churn through deep snow, their typical oversize applications and the absence of snow-biting sipes in their large smooth lugs can challenge their on-road wintertime traction on packed snow and icy surfaces.
Founder at Tiresout. Used to be working as an engineer at Bridgestone Tires Akron Technical Center. The responsibilities included but were not limited to technical computing, indoor & outdoor testing of new tires.
Have a 96 Toyota Landcruier with a OME lift 3″ front 4″ rear. Replaced 265/75 16 with 255/85 16 got 45K miles out of first set they still had life left but tread was chucked up from gravel roads. Vehicle hands much better on HWY with the 255/85’s, does not wander. Tire performance is outstanding in snow and mud, never been stuck when aired down! If you are looking for the best off road tires on the market with a great price point the BFG KM’s are bar none! Waiting for the KM3’s to be produced in this size.
Fine for the first 10k miles they now ride so rough and are so noisy that I am looking at replacing them with plenty of tread life left on them. Great tire if you cn handle the noise. I can’t.
Really Loud, not very good in Sand or Rock, thin sidewalls – lots of guys in my group have destroyed KM2s on the Rocky AZ trails. Wear fast and chunk quickly. I switched to the KO2 and they’ve been amazing, perfect in everything so far (we don’t have much mud in the Southwest so I can’t really speak to the one thing the KM2 is allegedly better at).
Just a quick word on these as new tires. The noise is a midtoned hum, not a rumble, although at very low speeds you can feel the rumble as you pull away from a stop. They are very stiff and heavy – which is a plus offroad, albeit a very minor negative on-road.These are approximately 33″ diameter (OEM is 29″ diameter 225/75R16 and I am reviewing the 285/75R16 tires) and they fit just fine on a stock JKU Sport with no lift. The wheels used have a -16 mm offset, although that could easily have been as high as +30 mm without any possibility of contacting the fenders or body (OEM is +50 mm for steel wheels). Offroad, I have not studied the clearance under high articulation.On 16×8″ rims they look extremely good.
Roughly 12,000 miles of mostly highway/city use on current set of tires.Tires perform great on dry roads, less so on wet roads, and even less on light snow/ice. They manage to fight hydroplaning pretty well because of the large empty spaces in between the tread lugs, but fall short on wet roads.Their ability to perform in deep snow will be affected by how much ground clearance you have until your body/axles start to hit the snow also. Past about a foot they struggle *on my setup*.When these wear out I’ll likely go to a different tire brand and size, not necessarily because of my experience.
Had these on my Jeep for several years, and so far they have held up well. After about 15k miles, there is about 50% of the tread left. However, I will replace these tires very soon due to noise and terrible traction when wet or on packed snow. There is no problem with hydroplaning, but braking and accelerating easily makes them skid or spin. Off road traction is acceptable, but the aggressive tread pattern quickly digs into loose sand if one is not super gentle and aware. On rocks and gravel, the tires do well. I realize that these tires have a stellar reputation amongst the hard core off roaders, but for me they are simply too noisy and feel lousy on the street. Having said that, I never had a flat or puncture, even when airing down to 15lbs for off roading and mild rock crawling. Perhaps best to use these for off roading only.
I bought these tires 4 or 5 years ago and a friend told me he thought I would get 20 thousand miles out of them because of their soft compound. It has been 55 thousand miles and there is still enough tread left for another 5 thousand before they become unsafe. I have had zero problems with them and I am getting ready to buy another set. I used 8 oz. of Air Soft pellets inside each tire for balancing. They are a little expensive but they have surpassed my expectations and I do not know what more I could ask for a set of tires. I have had no oppertunity to use them in ice or snow so cannot speak to their ability in those conditions. My vehicle is not a pickup but a 1985 Toyota 4Runner and I am using the 33″ 10.50 tires.
I purchased my set of BF Goodrich KM2 tires in 2013 (35×12.50R15). Overall these tires have been very good, though in some areas I think they are a step down from the previous KM(1) tires I had before, most notably they are downright LOUD!! (the stereo volume doesn’t quite work well enough to get over these babies lol), and when brand new they were only 34.5″ whereas the KM was 34.9″ measured the same way (inflated to 30PSI, not mounted on the vehicle).Treadwear has been beyond outstanding. After 35K miles (mostly highway, it’s never trailered) I still have close to 50% tread depth left across all 4 tires (I feel there’s at least another 25K there before they hit the wear bars). I’ve only rotated them maybe 3 times too. Offroad traction has been excellent (among the better tires I’ve owned). Vehicle stats also include locked F&R differentials and crawl gearing (I spend much of my time on trails in California’s Sierra mtns.). The sidewalls have suffered a few cuts & abrasions from rocks (one just barely touched the cords) but no punctures.My hopes are that the upcoming KM3 will be just as good, but with a noise level more akin to the previous KM tire (far from silent, but not so much that my ears bleed, and I can actually hear the stereo a little). Certainly the KM3 is a better-looking tire too.
