Product Features

Made to Mud

The BFGoodrich Mud-Terrain T/A® KM3 has 5 percent better mud traction than its predecessor. “Mud-Phobic” bars on the tyre’s shoulders are designed to release compacted mud for enhanced traction in muddy or soft soil conditions. The tyre’s Terrain-Attack tread pattern includes massive tread blocks designed to deliver incredible grip from any angle of approach.

Built to Climb

The advanced Krawl-TEK compound in the BFGoodrich Mud-Terrain T/A® KM3 delivers 8 percent better rock traction that enhances grip on rock and other slick surfaces. The tyre’s Linear Flex Zone allows it to envelop objects at reduced inflation for even more grip when climbing. The Traction-Armor Sidewall Sculpture and notched shoulder design also boost traction capabilities in soft soil and mud.

Created to Conquer

The BFGoodrich Mud-Terrain T/A® KM3 was designed to conquer the toughest off-road challenges with extreme sidewall protection, pinch shock resistance and chip-and-tear resistance on gravel. Its sidewalls are 27 percent tougher, thanks to CoreGard Max race-proven technology derived from the BFGoodrich Baja T/A® KR3 desert-racing tyre line. This technology helps prevent splitting or puncturing with increased thickness that protects the critical sidewall failure zone.The BFGoodrich Mud-Terrain T/A® KM3 also offers solid street performance and acceptable on-road noise levels for the rides to and from the trail.

Frequently Asked Questions
  • BFGoodrich Tires introduced the world’s first radial mud-terrain tyre 38 years ago with the launch of the BFGoodrich® Radial Mud-Terrain T/A®. Our newest edition – KM3 – is our 5th generation of mud products and fits within the extreme off-road portion of the LT portfolio, just under the Krawler™ T/A® KX. The KM3 tyre is designed to be “must-have equipment” for serious enthusiasts when conditions require extreme toughness and traction.

  • KM3 is truly “Built through experience … earned on the trail.” Years of experience and testing in some of the toughest conditions on Earth have resulted in a product that is improved over its predecessor and meets the needs of serious off-road enthusiasts:

    • 5% better mud traction* from its Terrain-Attack tread design.

    • 8% better rock traction** thanks to Krawl-TEK tread compound.
