It was time to upgrade my old 35″ Wild Country XTR Mud Terrain Tires.  My goal was to find a tire with good on road manners and excellent off road traction.  After hours of researching and reading reviews my choices were narrowed down to the Yokohama Geolander MT+, Toyo Open Country MT and the BFGoodrick T/A KM2 tires.  I decided to try the new BGFs.

The new BFG KM2 tires look incredible!  They share a similar tread design and styling to the award winning rock-crawling counterpart the Krawler KX.  Yet… It is a functional dual purpose tire.

The primary complaint I found online was poor snow and ice traction; this is mostly attributed to the lack of tread siping.  In contrast, the Toyo MT tires come with factory siping and have excellent snow/ ice traction; unfortunately they are nearly twice the price!

The solution was aftermarket tire siping peformed by the folks at America’s Tire / Discount Tire.  I opted to only have the center lugs siped to increase on road traction and increase tread life.  The outer lugs were left un-siped to limit tread chunking off road.

The tread siping was well worth the cost.  On a recent trip to Mt Bachelor the truck performed very well.  It stayed under control at all times with plenty of traction in packed snow and iceWet traction has also been excellent.  Siping the KM2 tires is highly recommended.

The on road manners of the KM2 tires is excellent.  It is quiet for a mud terrain tire and there isn’t excessive humming or vibrations at highway speeds (70 mph).  The noice level is comperable to many all-terrain tires I have driven in the past.

The tires balanced with a limited amount of weight and have no wobble or unevenness.  You won’t feel the aggressive lugs even at slow speeds unlike the Yokohama Geolander MT+ which feels like you’re driving on cobble stones.

Gas mileage decreased slightly  (1-2 mpg); in part due to the larger diameter compared to the old tires.  Note: these tires measure larger than most 35″ tires on the market.

The BFG KM2 tires are an excellent choice if you desire good on road performance and aggressive looks.  Be sure to read Part II:  BFG KM2 Mud Terrain Review Off Road

    I have been thinking about buying these tires in a 35. do these come with black sidewall or are they white print?

  2. Ah Yeah says:

    One side is black the other side is white. Great looking tires. I’ve been very happy with them on-road. Verdict is still out off road. Still testing.

  3. anthony says:

    i just ordered 265 75R16 and i am thinking of siping the tires. although i dont do any rock climbing, i might considere siping the edges also.

  4. I wouldn’t recommend siping the outer lugs. You might talk with the tire company about that too. Be sure to share what you think about the tires too!

  5. Kim says:

    I worked at les schwab(tire company) for 3 years. If you do off roading don’t sipe the tires at all, espically the edges. The siping cuts the slits in the tire to give it better performance on the road, but when your off road it can easly take chunks out of the tire. In that case your tire doesn’t look good and very commonly can make the tire pop.

    Thanks for the quick review. I’m from the south, but have move up north and have concerns about the winter.

    Discount Tire can warranty your tires so I’m guessing if you loose a good amount of rubber when offroading it will be covered.

  7. My understanding is Discount Tire will replace the tire if it is damaged beyond repair. Wear or abnormal wear is not covered.

    I have driving on many challenging rock boulder trails and not had any issues. The tires have an incredible amount of traction off road when aired down properly.

    I am wondering more about the km2′s as compared to bfg a/t’s (those common ones most suv’s and trucks have) I just wanted to know whats the tread wear life? i do know that the a/t’s usually last 50,000 miles more or less, and this one guy told me the km2′s usually last 15,000-20,000 miles, I need cold hard facts before buying km2′s althought they do look very sweet and benefit many good factors, i just moved from texas to salt lake city, and never been on snow, now i am concerned as well you have mention sipping the tires. On my bfg’s a/t’s i have around 80% tread life left, should i stick with these through out the winter or should i go ahead and go for km2′s, I drive a 2000 jeep tj w/ 6in lifted and 33′s, i do want to upgrade to 35′s. Thank you for reading.

  9. The KM2 tires are fairly new so tread life isn’t well documented. Much will have to do with vehicle weight, driving style, proper inflation, rotation and open vs locked differential. From my research it seems reasonable to expect 40-50k from properly maintained KM2 tires. I’ve heard many reports of the BFG AT tires with 50-70k miles. KM2 tires will perform better in most off road driving. The BFG AT tires will perform better on road, snow and ice. You’ll need to make the decision based on the type of driving you do. There are drawbacks to either tire.

    I’ve been very happy with my KM2 tires. The traction off road is incredible. They are amazing in the rocks. I’ve been running them at about 8-9 psi. I have about 7k road miles on them including a 4,600 mile road trip (still look new).

  10. Mike says:

    what is the poundage that you are running on road? i have a dodge diesel which like other diesels weighs a lot. i am at 35psi on road. any recommendations?

  11. I was running 38-40 psi. My rig only weighed around 4,000 lbs. Try increasing to 40 PSI and check how evenly the tire is contacting the ground. I found that the tire had less rolling resistance for my truck around 40 PSI. You may want to go higher.
