Excellent Tire!

37×13.50s are amazing on and off road. I love the performance off road, my jeep grips better than many others. I run with vehicles that have lockers and still keep up unless it's a clearance issue. They are well mannered on the road as well. Wish I could get white letters in 37+ sizes

I dunno…not happy :(

I have these tires on my Willys Wrangler. I like the look, but one has cupped really badly. I had my suspension checked out and it’s fine, so I’ve got to buy a new tire, which is super annoying because I’d prefer to have all of my tires the same age. Booooo.

Out performs every other tire

I have had these tires for over six months and put a considerable amount of miles on them in six months, between driving a lot of highway miles and a lot of off-road miles they hold up. all of my wheeling buddies run other competitive MT tires and none of them grip up nearly as well, I have used them in snow, mud, dirt, and slick rock, and I have not been impressed by the competition. KM3 is my go to tire for sure. also surprisingly quite at highspeed and around town.

B/O Quality Tires

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.

DuramacCz, our records indicate that we have talked to the retailer regarding your tires and although there is no warranty coverage for mileage or uneven wear, a concession was granted as a one-time offer.

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.

Out of round

Bought these in Feb. finally put on and have less than 100 miles on them. Out of round. Jeep wobbles. Contacted bfg. Being replaced but still won’t be able to drive my Jeep again for another 1-2 months. Going back to Nittos. Never an issue with those.

Excellent off-road; noise and squirrelly on-road

Love the tire off road, performs excellent and absorbs a lot of shock and impact. They are heavier and mileage has decreased. I’ve had them since 2019 and have put @ 15k miles on them. Still holding at 70% tread life. Rotate every oil change. Here’s the kicker; they are squirrelly on the freeway and like to wander the lane. They can be a bit wishy washy if you have to abruptly lift off the throttle. I’ve put BFG on all my cars and trucks for near 20 years and always will. I think when these go, I’ll back down to the AT’s. Lastly, I did buy a fifth spare MT so I’ll be offloading a new MT to swap to AT’s. Love the tire, off road they are king, on road you need to be ready to provide extra driver input.

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!!!

More information required on website

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)

Another Jeep in Alaska
5 out of 5 stars review

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.
