A balanced non-deflatable vehicle tire providing balanced operation even after partial puncture, adjustment of overall air pressure, use of standard rimmed wheels, and the option of being retrofit into existing tires, by providing alternating layers of puncture-resistant sheet material and pressurized-cell sheets, and an inner-tube to fill the remaining internal space and to adjust and apply balanced pressure internally.

A wheel resonator for reducing a resonance phenomenon inside a tire of a vehicle may include a plurality of wheel resonators mounted to a tire wheel. First and second wheel resonators of the plurality of wheel resonators are fixed with each other by a fastening part including a protrusion disposed on an end of the first wheel resonator penetrating through a hole disposed in an end of the second wheel resonator. An end portion of the protrusion has a size greater than a size of the hole. As such, quality of a wheel through more reliable noise reduction by making a wheel resonator in a manner of forming a fitting type fastening part in the wheel resonator itself and fixing the wheel resonator by ultrasonic welding can be improved.

Disclosed are an explosion-proof tire hub, including a hub body and an explosion-proof convex retainer. The hub body includes bent portions configured to mount a vacuum tire, the hub body is provided with a central axis, the explosion-proof convex retainer is fixed on the hub body, the distance between an upper end of the explosion-proof convex retainer and the central axis is L1, the distance between an upper end of the bent portion and the central axis is L2, and L1 is greater than L2. In case of burst or instantaneous pressure loss, because the distance L1 between the upper end of the explosion-proof convex retainer and the central axis is greater than the distance L2 between the upper end of the bent portion and the central axis, the explosion-proof convex retainer reduces the distance between the whole hub and the ground during tire burst and improves safety performance.

A multi air chamber tire 1 includes a partition wall 30 configured to define and form a plurality of air chambers 20 disposed adjacent to each other in an inner cavity of a tire, and a ventilation member 10 provided to the partition wall 30, and configured to connect the plurality of air chambers 20 in a state where ventilation is allowed. The ventilation member 10 allows ventilation between the plurality of air chambers 20 when a predetermined condition is satisfied indicating that fluid is being injected into at least one of the plurality of air chambers 20 from outside of the tire, and the ventilation member 10 shuts off the ventilation between the plurality of air chambers 20 when the predetermined condition is not satisfied.

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 an explosion-proof tire, comprising a safety airbag, trigger sensors and a safety switch, wherein the safety airbag is arranged between a tire and a hub; the hub is provided with grooves; trigger devices of the safety airbag are arranged in the grooves; one end of each trigger sensor sticks into the tire; and the other end thereof is connected with a trigger device. The safety switch is arranged on the valve stem of the tire; and positive and negative electrodes on the valve stem are each connected with a trigger device. The safety switch disclosed by the present invention ensures that the safety airbag will not be triggered accidentally, and when a vehicle tire bursts, the safety airbag provided can instantly provide enough support force to ensure traffic safety.

A self-sealing pneumatic tire having at least one cohesive sandwich radially inward of the pneumatic tire is provided. The at least cohesive sandwich may include a cohesive material under pressure, facilitating a recovery capacity upon being pierced by a sharp object, whereby the molecules of the cohesive material cohesively reattach, self-sealing any passageway or space created by the sharp object. The self-sealing pneumatic tire may also provide a loculated-diamond-section layer located radially inward of the outer cohesive sandwich, further supporting the self-sealing pneumatic tire. The external rubber tread are disposed along the circumference of the tire in some embodiments can be separate from the surface of the tire yet secured in place by attachments. Once fully utilized, this external rubber tread can be replaced by a new version without having to replace the entire tire.
