The solid tire is a kind of tire corresponding to the pneumatic tire (hollow tire). The earliest tires are solid tires. Solid tires are currently only used for high-load vehicles or machinery that travel at low speeds, and are also used for fixed-position machinery.

Solid tires are generally divided into two types: bonded and non-bonded. The former refers to tires whose rubber is directly vulcanized on the rim, and the latter refers to tires that are vulcanized and then fixed on the rim. According to the shape, it is divided into cylindrical solid tire and inclined bottom solid tire; according to the application, it is divided into antistatic, conductive, oil-resistant, high-load solid tire, and environmentally friendly non-marking solid tire.

Solid tires are generally used under high load, and the rubber compound is required to have sufficient pressure resistance and wear resistance, high enough tensile stress, high hardness, low permanent deformation and good wear resistance.
Solid tire is an industrial tire suitable for running vehicles under low-speed and high-load harsh conditions. Its safety, durability and economy are obviously superior to pneumatic tires, and are widely used in various industrial vehicles, military vehicles, construction machinery. , towed vehicles in ports and airports, etc.
