They're Only Available in One Size, But the KMs are Among the Best!
BFGoodrich changed the light truck tire world with the introduction of its 12R15LT Radial All-Terrain T/A in November of 1976. Since then, it's maintained its leadership in off-road light truck tires, fending off challengers over the years.
The current BFGoodrich Mud-Terrain, the KM2, is a respectable tire that is a jack-of-all-trades, but master of none. This tire, the LT255/75R17 Mud-Terrain T/A KM harks back to the earlier BFG Mud-Terrain tread pattern and is the OE tire on the Jeep Wrangler Rubicon. It's only available in this one 32-inch size, which is a pity. The KM is one of the best tires available today.
While it reminds us of the older BFG Mud Terrain tread, the KM's tread pattern was new when introduced in 2006. With DiggerLugz upper sidewall traction bars and tread clearing shoulder void bars, improved high-void tread design, interlocking tread elements and advanced compounding, along with BFG's TriGard three-ply polyester carcass, the KM works better than any other BFG Mud Terrain ever has.
Yes, the KM works. It works well on the pavement, in the rocks, in the sand, in the snow, in the dirt, and in light mud. They aren't too heavy, either. They balance easily and we've never seen a KM that exhibited much radial or lateral run out. When brand new, the KMs are silent and smooth on the pavement. As they wear, they start to emit a slight noise, but it's not intrusive until they're worn out. Off road, the KM's amazing performance is becoming legend. The compound mentioned earlier is sticky on the rocks while the tread design easily pulls the JK through deep sand and dirt. We didn't have mud when we shot the photos, but the KM's mud performance is okay, although if you have gumbo clay mud, they're overpowered quickly.
BFGoodrich Mud-Terrain T/A KM tires are outstanding tires. If you own a smaller SUV or just run 32-inch tires on your rig, these should be your first choice when purchasing tires. They really are that good.
Come on BFG, build the KMs in more sizes!
