BFGoodrich Mud-Terrain T/A KM

Part #: None

I was looking for a new set of tires for the 4 door. I had already decided that I would go with 35's until the axle and gearing was really worked out for the JK's. I may move up to 37's at some point, if I feel the need. I would rather have a little more challenge. I had run Dunlop Mud Rovers on my TJ and were satisfied with their performance, but they wore quickly and in the end offered me less value for the money than the BFG's and Goodyear's that I had in the past. Having the new Jeep come with BFGoodrich's made me decide to go back to them for the 35's.

BFGoodrich Mud Terrain


The Goodyear Wrangler MT/R (Maximum Traction/Reinforced) was developed to meet some of the most punishing conditions found in America. From the rock beds of Moab, Utah to the mud pits at Goodyear’s San Angelo Proving Grounds, the Wrangler MT/R has earned the right to be called Goodyear’s toughest Wrangler Off-Road Maximum Traction radial. However, conquering mud is only one weapon in the arsenal of this tire, withstanding daily driving abuse is another.

On the outside, the Wrangler MT/R uses an aggressive tread design made up of independent lugs which even reach far over the tire’s sidewall, giving this tire a rugged look and added traction when you need it the most. Inside, advanced silica compounds combine with Goodyear’s patented Durawall construction (the three body plies of high modulus polyester cord used for the tire’s carcass) provides cut, tear and puncture resistance that can take you where you want to go with freedom from worry. Finally, the Wrangler MT/R features a wider footprint, an advanced tread design and new mold shape technologies to provide a much longer life than the previous MT.

The Dunlop Radial Mud Rover is Dunlop's ultimate off-road tire.

The Mud-Terrain T/A KM (“KM” stands for Key benefit Mud) is BFGoodrich’s Off-Road Maximum Traction light truck tire designed to be the rock-climbing, mud-eating, and terrain-taming king. The Mud-Terrain T/A KM was developed to meet the needs of pickup truck and sport utility vehicle drivers who desire maximum off-road traction.

On the outside, the Mud-Terrain T/A KM features an advanced tread compound molded into a symmetric tread pattern comprised of large interlocking center tread blocks and alternating width “DiggerLugz” that extend over the tire’s shoulders to provide the clawing necessary to dig down, as well as, work against the sides of muddy ruts for added pulling power. The computer optimized high-void tread design generates less noise than BFGoodrich’s original Radial Mud-Terrain T/A, and provides a larger and more rectangular footprint to further enhance rock climbing and slick surface traction. On the inside, the Mud-Terrain T/A KM features twin steel belts on top of BFGoodrich’s TriGard (3-ply polyester cord sidewall plies) construction for strength and durability. Single strand beads (a single strand of bead wire is continuously wrapped multiple times until the desired strength is provided) enhance the tire’s fit to the wheel to improve uniformity and ride quality, while rim protectors molded into the lower sidewall help shelter the tire and wheel from off-road hazards, especially during aired down situations.

Common Sense and Safety should always be observed when working on your vehicle or doing modifications. Jackstands, wheel blocks, disconnecting the battery are a few of the basic safety precautions that should be used and may not be mentioned in the write ups on this site. You are responsible for your own installation, these write ups are a helpful guideline and should not be taken as an official installation instruction. My write up may be different from the kits currently out there, so alwasy double check the manufacturers installation instructions when installing anything. I try to keep the site up to date with changes that have occured as I discover them, but may not have the latest unless someone lets me know. If you feel that an install is above your capabilities after reading my write ups, I recommend getting together with a club and getting some help. Only a few times have I needed to employe some actual help from a shop to get something done. Usually welding or A/C work.
