A solid rubber tire is a type of tire that requires no inflation and is entirely made of rubber (or rubber composite materials). With its unique structure and performance, it demonstrates irreplaceable advantages in specific scenarios.

The outer layer, which directly contacts the ground, adopts a highly wear-resistant rubber formula to enhance wear resistance and anti-slip performance. The middle layer is mostly made of elastic rubber material, which is used to absorb vibrations, alleviate impacts, and improve driving stability. The inner layer usually incorporates fiber cords or metal frameworks to strengthen the tire's load-bearing capacity and structural stability.

Compared with pneumatic tires, its most prominent feature is the independence from air pressure, completely avoiding problems such as tire blowouts and air leaks.
