Background

Tubeless pneumatic tires, such as vacuum tires, also known as low pressure tires, inflated tires, are increasingly used in vehicles such as bicycles, motorcycles, cars, buses, trucks, and the like because of their high elasticity, wear resistance, good adhesion and heat dissipation. The bicycle is divided into different types according to different use scenes, different types of tires are required to be configured, the use modes are different, for example, the bicycle is used on rugged sites such as woodland, sand and the like, because the sites are rugged and rough, users do not want to fully charge the air of the tires when riding, so that the contact surface between the tires and the ground is small because the elasticity of the tires is too high, the grip of the tires is insufficient, and the riding is influenced, and therefore the tires of the bicycle are often in an incompletely inflated use state to enhance the grip.

However, in the actual use process, the service life of the rim is greatly influenced by the incompletely inflated tire, because the rim (or the wheel hub or the wheel rim) of the tire can frequently directly contact the ground or hard obstacles on the ground to receive a large impact force in the riding process, the rim is deformed in a long term, the service life of the rim is seriously influenced, and the riding experience of a user is poor; furthermore, when the incompletely inflated tire is used, the matching part of the tire bead and the rim is repeatedly extruded and rolled, so that the tire is easily damaged, and the service life of the tire is influenced; furthermore, during use, the crushed and deformed tire may be directly separated from the rim, causing danger.
