An airless tire is a type of tire designed to eliminate the need for air pressure, making it puncture-proof and more durable. These tires are typically made from a solid or composite material that provides support and flexibility, allowing them to maintain their shape and performance without the risk of deflation. Airless tires are often used in various applications, including bicycles, construction vehicles, and military equipment. Their design can lead to lower maintenance costs and increased safety, as they do not suffer from blowouts or air loss like traditional inflated tires.
