Overview
The BF Goodrich 32×10.00R15NHS Mud-Terrain T/A KM3 (part number BFG40964) is a UTV tire 32 inches high, 10 inches wide, with black letters on the sidewall for a 15-inch wheel.
The KM3 is designed for mud, rock and rugged trails. The Terrain-Attack tread, Mud-Phobic Bars and Krawl-TEK compound target traction, while the sidewall uses CoreGard Max technology and Traction-Armor Sidewall Sculpture. The sidewalls are 27% tougher.
At 32 inches, this tire gives UTV owners a large-diameter option for a 15-inch wheel, so measure your wheel wells and consider steering and suspension travel.
This KM3 uses a Mud-Terrain T/A style with black letters on the sidewall. Check the ply rating, load index and weight against your build before ordering if they matter to you. The NHS suffix is part of the size code.
Key features
- 32-inch tall Mud-Terrain T/A KM3
- Black letter sidewall
- Terrain-Attack tread blocks with Mud-Phobic Bars
- Krawl-TEK compound for rock grip
- Linear Flex Zone for aired-down driving
- CoreGard Max and Traction-Armor Sidewall Sculpture protect the sidewall
Gearing and speedometer changes
A taller tire turns more slowly for each revolution of the drivetrain, so it changes the effective gearing of the machine. Owners often notice weaker acceleration and less pull at low speed, and the machine may feel different on hills. The change is not limited to performance, since speedometer and odometer readings shift with the new rolling diameter.
Before mounting a tall mud tire, think about the drivetrain and brakes as a whole. Some owners pair a tire like this with gearing or drivetrain adjustments, while others accept the change for the added ground clearance. Measure the wheel well and suspension travel, and plan for a shop to balance and mount the tire on a 15-inch wheel.
- Expect changes to acceleration and speedometer readings
- Check brake and drivetrain behavior after the first drive
- Plan for a shop to mount and balance the tire

Vehicle fitment
BFG40964 is not assigned to a particular vehicle. It is picked by size, and no model, years or chassis code are given.
Because the tire stands 32 inches tall, it suits UTVs with 15-inch wheels and plenty of fender room, and it will not seat on wheels of another diameter. Other KM3 sizes carry different part numbers.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
A 32-inch tire often rubs on stock UTV bodywork. Check clearance at full lock and full compression, and plan for mounting on a 15-inch wheel by a tire shop. A taller tire also changes gearing and speedometer reading on most machines, which is worth keeping in mind.
