Excellent Offroad Tire

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.

I love them

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.
