Not only are the angles (?, ?) that the steel cords in the second and third belt plies (8, 9) form with the circumferential direction (A-A) approximately equal, but also the angles (?, ?) that the steel cords in the first and fourth belt plies (7, 10) form with the circumferential direction (A-A) are likewise approximately equal.

Abstract: A vehicle tire has outer shoulders and two tread halves. The tire includes a tread having six block rows and a plurality of circumferential grooves. Mutually adjacent ones of the block rows are separated from each other by a corresponding one of the plurality of circumferential grooves. Each of the block rows has individual blocks separated from each other by mutually parallel essentially straight transverse grooves running at an angle to the axial direction of the tire. The circumferential grooves include first circumferential grooves having a maximum profile depth and second circumferential grooves having a second profile depth less than the maximum profile depth. The transverse grooves have a depth approximately corresponding to a maximum profile depth at first outlet locations. The transverse grooves have a depth corresponding to the second profile depth at second outlet locations.

Abstract: A process for producing an environmentally-friendly plasticizer, which is particularly suitable for use in vehicle tires or technical rubber articles. A vulcanized and/or unvulcanized polymer material of a high molecular weight is converted into a low-molecular phase by direct thermal liquefaction. The vulcanized and/or unvulcanized high-molecular-weight polymer material is provided as a polymer powder and/or a granulated polymer and can be obtained from used tires.

Abstract: The invention relates to a bicycle tire with high riding comfort. A damping rubber insert (3) made from a highly elastic rubber is arranged between the tire tread (2) and the tire carcass. Said damping rubber insert (3) has a material thickness of between 0.2 and 2 mm, and the carcass insert ends (10) extend to a maximum of the lateral edge areas of the tire tread (2).

Abstract: The invention relates to a pneumatic vehicle tyre with a sound-absorbing inner absorber (9) adhesively attached in its interior to the inner surface (7) opposite from the tread (1), wherein the inner absorber (9) adheres to an automatically sealing sealant (8), which at least immediately after being applied has the tackiness required for the adhesive attachment. In order not to influence the flow properties of the sealant disadvantageously and in order to ensure a reliable sealing effect of the sealant, a separating layer (10) is arranged between the sealant (8) and the inner absorber (9) and the separating layer (10) is made in such a way as to ensure a sufficient flowability of the sealant (8) for the sealing and a reliable adhesive attachment of the foam ring (9).
