Overview
The BF Goodrich 28×10.00R14NHS Mud-Terrain T/A KM3 (part number BFG33172) is a UTV tire built for mud and rocky trails, sized for a 14-inch wheel and 10 inches wide.
The KM3 is a tire built to take a UTV almost anywhere. Its Terrain-Attack tread uses large tread blocks meant to grip from any angle, and Mud-Phobic Bars release compacted mud so traction continues. CoreGard Max sidewall technology and Traction-Armor Sidewall Sculpture are designed to help the sidewalls resist sharp objects and splitting.
This version carries the 28×10.00R14NHS size designation, with an overall height under 30 inches. Anyone looking for a KM3 in a 28-inch height for a 14-inch UTV wheel will find that exact size here. The name BFGoodrich gives this range, Terrain-Attack, refers to a tread meant to work on mud, loose soil and rock rather than on pavement alone, so expect a trail-focused tire.
The NHS letters at the end of the size are part of the size code, and the tire is typed as a UTV tire. Ply rating, load index, weight and tread depth should be confirmed for your build before buying.
Key features
- Terrain-Attack tread with massive blocks designed to grip from any angle of approach
- Mud-Phobic Bars that release compacted mud
- Krawl-TEK compound aimed at rock and slick-surface grip
- Linear Flex Zone that lets the tire flex and envelop objects when aired down
- CoreGard Max technology: a thick sidewall shield with a specialized compound against sharp objects
- Traction-Armor Sidewall Sculpture to help prevent sidewall splitting
Trail setup and pressure
Running a tall 28×10.00R14NHS tire on a UTV changes the way the machine handles. The added height raises the center of gravity and increases the load on wheel bearings, axles and steering components, so tire choice should be paired with a check of the drivetrain. Clearance at full steering lock and full suspension travel is the first thing to confirm, since a tire that rubs can damage fenders or the frame.
Tire pressure is the main tuning tool on a mud and rock tire. Lower pressure lets the tread envelope rocks and roots, while higher pressure helps on hard-packed trails and reduces the risk of a bead coming off the rim. Air down in small steps and check the tire after each change, and always re-inflate before highway driving.
Between trips, look at the sidewalls and tread for cuts, embedded stones and bead damage. Check lug nut torque after the first drive, and re-check it after rough sections. Clean caked mud out of the tread so the Mud-Phobic Bars can do their job next time out.

Vehicle fitment
BF Goodrich markets this tire as a universal-fit UTV tire, which means it is picked by dimensions rather than by a named vehicle. No years, models or chassis codes are given for BFG33172.
A UTV needs 14-inch wheels and enough wheel-well room for a tire under 30 inches tall. Other KM3 sizes use their own part numbers, and wheels of another diameter will not seat this tire.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Have the tire mounted and balanced on a 14-inch wheel by a shop that works on UTV tires. After mounting, turn the steering to full lock and cycle the suspension to confirm nothing rubs.
