I may be way behind on the times but I recently noticed that BFG introduced new KM3 to replace the KM2 Mud Terrains.

They have two sizes I'm interested in 37x12.5r17 or the 39x13.5r17 sizes

I bought 37x12.5x17 KO2 All-Terrains not long after they were introduced, I'm sure anyone reading this can find those pics on some Hummer forums

The KO1/2 37's should have been the factory tire size, they seem stock and fill out the wheel-wells as it should.

Now for numbers:

KO2 37x12.5r17 actual size is a small 35.6 inches brand new, fairly small for a 37 but perfect for the H2 and doesn't drag out all power.

KM3 37x12.5r17 actual size is 36.5 inches - much better

KM3 39x13.5r17 actual size is 38.5 inches - almost too much


Interested to see these start trickling onto our trucks. Love to see pics preferably on stock rims if anyone has bought the new KM3's
