1Void Ratio and Hydrodynamic Clearance
Mud-terrain (M/T) tires are designed with high void ratios (up to 55%), meaning over half the tire surface is open space. This space acts as a hydrodynamic pocket, capturing mud and venting it out the sides as the wheel rotates.
- High Void Ratio: Wide channels trap mud, letting lugs bite solid ground.
- Transverse Channels: Curved grooves pump mud outward during rotation.
2Tapered Lugs and Mud Ejectors
To prevent clay from vacuum-packing inside the tread, lugs are designed with tapered sidewalls (10° to 15° angles). Small, raised rubber ribs—stone and mud ejectors—flex under load, cracking and releasing packed clay.
- Tapered Lugs: Release suction, allowing mud to slide out easily.
- Mud Ejector Ribs: Physical rubber bumps push out trapped gravel and clay.
3Rubber Hysteresis and Low-Temperature Flex
Off-road tires utilize rubber compounds with high hysteresis—meaning they deform easily over obstacles and damp rebound forces. High silica content ensures the rubber remains pliable in freezing, wet mud, maintaining grip.
- High Hysteresis: Rubber molds around obstacles for mechanical grip.
- Silica Enrichment: Keeps tread pliable in cold, wet mountain mud.
