I've been a loyal BFGoodrich customer for years. My previous set of KM2s was outstanding. They wore evenly, performed exactly as expected, and gave me every reason to buy another set. So replacing them with the KM3 was an easy decision. Unfortunately, this experience has been very different. At roughly 30,000 miles, (3) of the (5) tires have developed significant cupping. Before assuming the tires were at fault, I did my homework. The suspension has been inspected, the tires have been properly rotated, and America's Tire also inspected them. I wanted to rule out every obvious cause before pointing a finger at the tires. I understand I'm outside the written warranty, and I'm not asking BFGoodrich to ignore its policies. What concerns me is that after reading other KM3 owner experiences, it appears I'm not the only customer who has experienced premature wear around this mileage. I chose BFGoodrich because of how well the KM2 performed. That's why this has been so disappointing. On a Jeep running a five-tire rotation, replacing three tires effectively means replacing the entire set to keep everything matched. I'm hoping someone at BFGoodrich is willing to review my situation as a goodwill adjustment. Loyalty is built over years, and sometimes the best opportunity to earn it is after a customer has a problem. I'd genuinely like my next set of tires to be BFGoodrich.

I bought KM3's, at the dealer and they installed them when they came in, soon after they came out for my new 2019 Silverado Z71 LTZ. They have 47,500 miles on them and still going. Soon, I will buy another set. I have the 33's, 12.5 in, 20 inch wheel.

I have around 40k miles on my 37" Tires and they still have around 5k miles left The tires a difficult to balance but running quiet on the road Offrad in the rocks they ripping out big chunks of rubber what's concerning Those tires are more like a true 35" tire and not a 37" tire Will probably try a different Brand next time

Man these tires are fantastic. After running Sedona’ on my side by side, these BFG’s made a huge difference on ride, grip and durability. I would definitely buy them again!

These are 45,000 miles off-road tires that might lack a little mud traction but make up in all other forms of off-road traction. They’re quiet on the streets, Good, breaking when, wet and tougher side wall with its polyester fibers embedded in the sidewall rubber making it virtually split proof

I love them. I’ve had all three versions of the mud terrain line on my truck (I have owned it for over thirty years, 316,000 miles). The original looked great, wore reasonably well but mileage suffered. The KM2 provided poor mileage and looked worn after 5000 miles. I didn’t like them at all and went to Cooper’s for the next set. I didn’t want to buy the KM3 when it was time for new tires but the comparable All Terrain was too wide for my wheels so I went ahead and got the KM3s (255/85 16- Tall and skinny). My mileage is back to what I was getting with stock tires. No noticeable road noise, of course my 4x4 Cummins is kinda noisy already. Finally, I’m not sure how many miles I have put on them but probably at least 10K and they still look the same as new. I’m not doing heavy offroad driving but snow, mud and steep gravel driveways have not been a problem so I think traction is more than adequate.

I’ve been running 37 and now 39” BFG KM3 for the last 8 years on two vehicles. They are outstanding tires. Provide great traction and are very durable in the rocks. They always easily balance and are significantly lighter than competitors mud tires.

Tire is high traction off road profile. I live in the mountains of Central Arizona. Most mileage is dirt, rocky off road with a mix of wet snow and occasional long hiway runs.

Noisy tire, I have gotten a lot of miles out of them. I have gotten 70,000 miles out of these tires.

I am the author of the previously titled Not Sure Yet review. We’ll I am pleased to tell everyone that after the remaining 3 tires were swapped and road force balanced, I am riding on a dream. Unfortunately I guess I got a bad lot of tires that seem to of had high spots on them. What those replace balanced it’s so nice to ride on new BFG‘s that are smooth, look great, perform great ad for a mud tire qiet on the road.
