A tire/wheel assembly includes a wheel including a disk and a rim, the wheel having a power reception device attached to an outer peripheral surface of the rim to receive electric power supplied wirelessly from farther outward in a radial direction of the wheel than the rim, and a tire attached so as to cover an outer peripheral surface of the wheel and including a pair of sidewall portions. A gauge of the sidewall portions is 1.5 mm or more.

A method of manufacturing a rim includes placing at least one braided sleeve on a core dimensioned to define a shape of an internal wall of the rim. The method includes inserting the braided sleeves placed on the core, inside a mold that is dimensioned to define a shape of an external wall shape of the rim. The method further includes injecting a resin inside the mold to contact the mold and impregnate the sleeves and other layers with resin. The method also includes curing the resin to form the internal and external walls of the rim and obtain a cured rim having the core connected thereto. The method further includes removing the cured rim and core from the mold and melting the core to get it out of the rim.

A flat tire safety system, having: (a) a pair of elongated semicircular members dimensioned to wrap around a tire rim and be positioned within a tire; and (b) a pair of clamping assemblies, each clamping assembly securing an end of the first elongated semicircular member to the end of the second elongated semicircular member, wherein each clamping assembly has: (i) a housing, (ii) a double-headed bolt passing through the housing, (iii) a tightening bolt mounted in the housing, wherein rotating the tightening bolt turns the double-headed bolt, (iv) a ratchet on the housing for permitting the tightening bolt to rotate in a tightening direction and preventing the tightening bolt from rotating in a loosening direction, (v) a release on the housing for selectively permitting the tightening bolt to rotate in the loosening direction, and (c) a pair of anchors, wherein each anchor is embedded in the end of one of the elongated semicircular members, and wherein one end of the double-headed bolt passes through each of the anchors.

The disclosure relates to a road noise reducing system including a wheel rim having a barrel, a first layer of acoustic metamaterial with a first plurality of open cells mounted on the barrel, and, optionally, a second layer of acoustic metamaterial with a second plurality of open cells in contact with the first layer of acoustic metamaterial. The system optionally includes a pneumatic tire with a hollow, wherein the tire is mounted on the wheel rim such that the hollow forms a closed cavity and can incorporate additional elements including an elastomeric membrane, a noise-absorbing foam, and/or a resonator. The system has a sound transmission loss of at least 20-35 dB at frequencies of 50 Hz to 2,000 Hz and can reduce tire-road interaction noise by at least 50-70%. Also disclosed are methods of making road noise reducing wheel and tire assemblies, automobiles incorporating the same, and methods for reducing tire-road interaction noise.

A vehicle wheel includes: a rim including a well portion and a guide member; and a sub-air chamber member serving as a Helmholtz resonator. The well portion has an outer circumferential surface extending in a wheel circumferential direction of the vehicle wheel. The guide member engages with the sub-air chamber member to guide the sub-air chamber member on the outer circumferential surface in the wheel circumferential direction, thereby to attach the sub-air chamber member to the rim.
