Currently, wheeled mobile machinery is widely used in ports and container yards. However, there are many safety risks associated with pneumatic tires, such as during loading and unloading and inflation. Solid tires, on the other hand, are not affected by these factors and are basically suitable for any environment.

Currently, the standard air pressure for large tires is 100 kPa. A tire with 10 kPa of pressure contains about 12 times the volume of air, with powerful explosive energy that can cause serious injury or death to nearby personnel. Particularly during tire disassembly, it often results in tire or rim ejection, causing casualties.

There are also many safety risks when inflating tires. If the rim is not properly installed, the rim can fly out and injure people when the inflation pressure reaches a certain level. During high-speed driving, sudden tire blowouts in small tires can easily cause vehicle rollovers, and flying tires can also cause casualties in the surrounding area. Solid tires do not have the safety risks mentioned above. The interior of solid tires is completely filled with elastic material, making them safer to use in any situation.
