Abstract: Motor vehicle wheel having a tire mounted on a rim and method of making the same. The wheel includes a ring made of a sound-absorbing material positioned inside the interior of the tire and encircling the rim. Threads are arranged to cover the ring to fix the ring to the rim. The threads are stretched over both sides of the ring one of towards or onto the rim. The method includes positioning the ring made of sound-absorbing material onto a circumferential area of the rim and stretching threads over the ring made of sound-absorbing material one of toward and onto the rim.

Abstract: Motor vehicle wheel including a wheel rim and a tire having a tire interior enclosed by the wheel rim and the tire. The tire is mounted on the wheel rim, and the wheel also includes an insert composed of a ring-shaped sound-absorbing material that is positioned within the tire interior. The wheel further includes an acoustically transparent support element having tensile strength, at least in a circumferential direction of the tire, that is coupled to the insert.

Abstract: An arrangement for reducing tire/road noise caused by a moving motor vehicle includes a spray water protective lining 3 in a wheel box 2 and/or a spray protective flap 41 mounted on the wheel box 2. The spray water protective lining 3 includes a composite layer structure which has at least one layer 17 for absorbing sound and at least one layer 11 for reducing spray mist.

Abstract: A device for reducing certain sound ranges of tire/road surface noise of a motor vehicle includes sound absorbers in the form of resonators positioned at the inner wall of a wheel well of the vehicle in the area of sound projection of the tire/road surface noise. The device has an electronic control device for receiving a signal preferably derived from an ABS system in the form of the wheel rpm. The control device adjusts the resonators according to the number of tread blocks of the tire, the sound emission characteristics, and the wheel rpm. In another embodiment the electronic control device is supplied with signals received from a sound receiver that records the course over time of the sound pressure. The control device adjusts the resonators such that the measured sound pressure signal is minimized. In another alternative the device has a data processing unit including an electronic control device.
