Military tires, as an important component of military products, play a significant role in national defense construction. At present, China's military tires are mainly supplied to wheeled combat vehicles, command vehicles, transport military vehicles, and military aviation. These military tires not only have stricter requirements than regular tires, but also use much more advanced technology than regular tires. Improving the bulletproof and explosion-proof capabilities of tires is the key to enhancing the combat effectiveness of military wheeled vehicles. In the past, rubber tires did not have bulletproof ability, and when a bullet pierced through, the car collapsed and subsequently became a live target. To address this issue, tire explosion-proof and bulletproof solutions such as self sealing technology, support technology, bead locking technology, and filler technology have been proposed and applied in military wheeled vehicles. The application of this series of technologies has to some extent improved the battlefield survival rate of military wheeled vehicles, but there are still many problems that need to be solved urgently. Taking a self sealing tire as an example, its essence is to spray a layer of polymer organic memory synthetic rubber material on the inner layer of the tire. Once the tire ruptures, this material will temporarily block the break, ensuring that the tire can continue to be used for a period of time. However, when there is a lateral rupture of the tire or a certain degree of damage to the tire, the self sealing effect is basically ineffective. The filling technology, support technology, and bead locking technology also have their own problems, such as heavy weight, reduced driving speed after damage, poor comfort, and limited battery life after damage.

The maintenance difficulties of inflating, blowing out, and repairing pneumatic tires restrict the combat effectiveness of military wheeled vehicles. The battlefield situation is constantly changing, and every minute can determine the outcome of the entire war. Tracked armored vehicles once dominated the market due to their excellent terrain adaptability and excellent protective capabilities. Although the tracked personnel carriers, tanks, and other weapon platforms equipped by heavy mechanized troops have excellent protective performance, they are too heavy to be deployed quickly. Although the off-road vehicles and transport vehicles equipped by light infantry units have good mobility, their survival ability is worrying. Wheeled armored vehicles can attack targets at speeds of 80-100 kilometers per hour, which is more in line with the characteristics of modern warfare. Therefore, wheeled armored vehicles have gradually developed, and countries have also established Quick reaction force based on wheeled armored vehicles. However, the shortcomings of the inflatable tires of wheeled armored vehicles, such as being prone to damage and long maintenance times, have always troubled maintenance personnel, making it difficult to fully utilize the rapid mobility ability of wheeled armored clusters under practical conditions.

According to our company's winning bid for the "Non pneumatic Wheel Technology for Wheeled Vehicles" project, our military non pneumatic tires have been successfully developed. The product is composed of wheels, spokes made of polyvinyl chloride resin, shear bands wrapped around the spokes, and tread, marking the transition from conceptual design to physical design for military non pneumatic tires. The tire can withstand advantages such as landmines or small arms strikes, and will continue to work even if 30% of the tire structure is damaged.

The project acceptance has been completed. The military non pneumatic tire has a rated wheel load of 2500kg, a wheel diameter of 1044mm, a maximum road speed of 120km/h, and an average off-road speed of 35km/h at the base; The maximum driving distance exceeds 20000km.

The future cooperation prospects of this product tire are broad, and the technology research and development has become mature, and it is currently in the promotion stage.
