[0002] Solid tires are a type of tire that corresponds to pneumatic tires (hollow tires). Their carcasses are solid, and they do not use cords as a skeleton. They do not need to be inflated, so they do not need inner tubes or airtight layers. The earliest tires were solid tires. Solid tires are only used for high-load vehicles or machinery traveling at low speeds, and are also used for machinery in fixed positions. Solid tires are a special type of tire. Solid tires are generally used under high loads, requiring the rubber to have sufficient pressure resistance and wear resistance, and have sufficiently high tensile stress, high hardness, low permanent deformation and good wear resistance. Solid tires are an industrial tire that is suitable for vehicles running under harsh conditions of low speed and high load. Their safety, durability, and economy are significantly better than pneumatic tires, and they are widely used in various industrial vehicles, military vehicles, construction machinery, and trailer vehicles at ports and airports.
