Vehicle systems and components are set forth, which aim to reduce rolling friction caused in part by the contact between the vehicle's tires and the ground surface over which the vehicle is traversing. These systems and/or components thereof may increase the overall fuel efficiency of a vehicle. In the examples provided, the systems and/or components change the tread contact patch of one or more tires during movement of the vehicle.

The present invention relates to a device for mounting tubeless tire comprising an elongated balloon having an opening attached to a bicycle tire valve. The balloon is fabricated from latex or any other suitable elastic material, and is filled with a tire sealant composition. Further, the ballon is designed to burst at a pressure of 15-40 psi.

Disclosed is a hollow tire with an inflating valve, including two parts: a tire body and an inflating valve. The inflating valve is disposed in the tire body, the inflating valve is a rubber gasket inflating valve, and an inflating valve rubber base and the tire body of the hollow tire are bonded by using a rubber vulcanization process to ensure gas tightness. An inflating valve body is hidden in the tire body of the hollow tire and can be located at any position on a cross section of the tire body of the hollow tire. Compared with an ordinary hollow tire, in this disclosure, the inflating valve is disposed on the hollow tire, so that high-pressure gas can be inflated, thereby enhancing a load-bearing capability and buffering performance and improving a service life of the tire.
