Speed Limitations

The Mammoth is limited to a maximum ground speed of approximately 52 km/h when unladen on a prepared haul road. This restriction is not due to engine power, but rather to the physics of its enormous 3.238-meter-diameter tires.

Each tire must flex slightly with every rotation to carry the vehicle’s immense weight. At higher speeds, that flexing happens more often per second and builds up internal heat. Because heat dissipation in rubber is limited by both size and compound, excessive speed can quickly exceed the tire’s TKPH (ton-kilometers per hour) rating—causing rapid degradation or catastrophic failure.

The Mammoth’s smaller-diameter tires already rotate faster than those on the larger BelAZ-class haulers, making them more prone to heat accumulation. To stay within realistic thermal and structural limits, the vehicle’s top speed is capped dynamically based on load, ambient temperature, terrain roughness, and grade.

In short: the Mammoth isn’t slow because of lack of power—it’s slow because even future-grade rubber can only take so much heat.
