TREAD PROFILE OF A VEHICLE TIRE

摘要

A tread profile of a vehicle tire has profile positives such as profile blocks or tread bands that have sipes. The sipes have an approximately Ω-shaped geometry in plan view having two axial sections which are arranged approximately in an axial direction and which are arranged on a common, imaginary straight line with a spacing (a) to one another; a central bulge arranged between the axial sections, wherein the bulge has a maximum extent (b) measured in the axial direction; and, wherein a

1. A tread profile of a pneumatic vehicle tire defining an axial direction, a radial direction and a circumferential direction, the tread profile comprising:
profile positives having sipes; said sipes having a sipe base and defining a depth profile and, when viewed in top plan, an approximately Ω-shaped geometry having:
two axial sections arranged in the axial direction and conjointly defining a common imaginary straight line, said two axial sections being arranged on said imaginary straight line at a distance (a) from each other;a central bulge arranged between said two axial sections and having a maximum expansion (b) measured in the axial direction; said distance (a) being less than said maximum expansion (b) so as to form undercuts; and, said central bulge having a maximum extension (c) measured in the circumferential direction and continuously decreasing over said depth profile such that said sipe ends in a straight line at said sipe base.
