Airless tires or non-pneumatic tires (NPT) operate without an inner tube & air pressure, and the composite spokes make a flexible ring that is connected to a solid inner hub to hold its shape. These tires have a rigid & complex construction, wherein a shear band is stretched across the spokes and the tread is attached to the shear band mounted on outside hub. An airless tire comprises treads, high-tension steel belts (protector ply, working ply, and transition ply), spokes, and a hub. The tubeless tire market is expected to witness significant growth during the forecast period, owing to its advantages such as easy puncture repair, increased comfort for higher speed, lower tire pressure, better bump absorption, and reduced rotating weight as compared to conventional tires.
