2026-05-08 This article explains why bias tires (cross ply tires) remain the preferred choice for mines, quarries, and other high‑impact conditions. Based on their multi‑layer crossed‑ply structure, bias tires convert instantaneous impact loads from stress concentration into stress diffusion through microscopic inter‑ply movement, thereby absorbing energy and preventing localized damage. Compared with radial tires, bias tires offer superior impact resistance, puncture resistance, crack propagation control, and heavy‑load lateral stability, making them ideal for low‑speed, high‑load, and rough‑terrain mining operations. The article also provides selection recommendations for dump trucks, loaders, and underground equipment, along with key maintenance tips. It concludes that bias tires continue to play an irreplaceable role in construction machinery and mining transportation due to their reliability and structural adaptability.
