  • Patent number: 9487053
    Abstract: A vehicle tire has a pattern visible in the side wall located in a groove thereof extending across the entire circumference of the tire and oriented in a circumferential direction (U). The groove is formed of first groove segments and second groove segments, which in the circumferential direction are arranged in alternating sequence one behind the other. Radially outwardly, the groove segments are each defined by a radially outward defining flank and radially inwardly, are defined by a radially inward defining flank defining the groove radially inward. The first groove segments are arranged radially outside the second groove segments and the transition between a first groove segment and the adjacent second groove segment is configured as a radial offset of the groove by the amount of displacement (a).

  • Patent number: 8733414
    Abstract: A pneumatic vehicle tire has a profiled tread, two side walls, and at least one protective rib running on the surface of the side wall over its circumference. The protective rib is disposed above and with a spacing distance from a side wall marking or a side wall decoration. The protective rib has a lower negative contour with at least one recess, which is configured to correspond to the positive contour of the side wall marking or side wall decoration facing the protective rib, such that the protective rib at least partially accommodates the upper half of the side wall marking or side wall decoration in the recess.
