  • Patent number: 8887780
    Abstract: A pneumatic vehicle tire, in particular for heavy commercial trucks, having a tread with a number of circumferential grooves which run in the circumferential direction and which separate profile positives, such as block rows or profile ribs, from one another. The circumferential grooves are each bounded by a groove base and two groove edges. In order to effectively prevent the occurrence of tears at the groove base of the circumferential grooves, in particular at the groove base of the circumferential grooves which extend on the shoulder side, the groove base extends, viewed in cross section and in the axial direction, at an angle of inclination of 3 degrees to 15 degrees with respect to an envelope which encompasses the outer faces of the profile positives.

  • Publication number: 20090294001
    Abstract: Vehicle tires, particularly for commercial vehicles, contain a profiled tread, which is broken down into profiled ribs or block rows by a number of peripheral grooves and is made of a first rubber mixture. A groove base of the peripheral grooves is made of a second rubber mixture, and the modulus of elasticity of the second rubber mixture is less than the modulus of elasticity of the first rubber mixture of the main part of the tread. In particular, the second rubber mixture has a modulus M 100%, which is 5% to 20% less than the modulus M 100% of the first rubber mixture of the main part of the tread. The two rubber mixtures are based on a substantially identical or comparable polymer system.
