Embodiment Construction

[0037] figure 1 Shown is a section through a tire of a commercial vehicle, the tire having a sealed inner layer 1, a carcass 2 (the carcass has in particular steel cords as reinforcing elements), the tire also has four A breaker belt assembly of the plies 3, 4, 5 and 6, sidewalls 10, bead regions with bead cores 7 and bead fillers 8, and a shaped crown 9. The carcass 2 is a radial carcass, the steel cords of which run substantially parallel to each other in radial direction from bead area to bead area. In the case of the embodiment represented, this fourth, radially outermost belt ply 6 is the narrowest of all these plies and forms the so-called protective ply. The first belt ply 3 is a barrier ply and the second and third belt plies 4, 5 are so-called working plies. The belt plies 3, 5 and 6 consist of steel cords embedded in a rubber compound, the belt rubber compound, and extend parallel to each other in each of the plies 3, 5 and 6 . The angle formed by the steel cords...

Abstract

The invention relates to a pneumatic vehicle tire having a profiled tread (1), two side walls (10), and at least one protective rib (11) running on the surface of the side wall over the circumference thereof, and wherein the protective rib (11) is disposed above and at a distance from a side wall marking (12) or a side wall decoration. The protective rib (11) has a lower negative contour comprising at least one recess (14), which is configured to correspond to the positive contour of the side wall marking (12) or side wall decoration facing the protective rib, such that the protective rib (11) at least partially accommodates the upper half of the side wall marking (12) or side wall decor in the recess (14).

Description

technical field [0001] The present invention relates to a pneumatic vehicle tire having a shaped crown, two sidewalls, and at least one protective rib extending on the surface of the sidewalls over the circumference of the sidewalls, and wherein the protective rib is Positioned above and at a distance from a sidewall marking or a sidewall trim. Background technique [0002] These protective ribs are known in the prior art on tire sidewalls, which are placed above and at a distance from sidewall markings or sidewall decorations in order to protect said sidewall markings or sidewall decorations from Contact with scratches, such as contact with a curb. It is intended to protect the markings or decorations from scratching contact so as to maintain their legibility throughout the life of the tyre, but also to prevent cracks caused by the notch effect. The protective rib is usually a rubber strip or wedge that is attached to the sidewall as a portion and extends at least in part...
