Tread profile of a pneumatic vehicle tire with an indicator for regrooving the profile
A regroovable treat profile of a pneumatic vehicle tire includes a regrooving indicator formed with an additional indent in the base of the depression in the form of a blind hole lying transversely in relation to the main direction of extent (u) of the groove and having a length of extent (a2) and an indent depth (b), where (b) is formed such that b<a2 and b<a1 and b<l and with a depth of extent (t2) where t2>t1, which is measured starting from the groove base inward in the radial direction (r) to the base bounding the indent radially inward. The depth of extent (t1) forms the measure for the minimum regrooving depth and the depth of extent forms the measure (t2) for the maximum regrooving depth..
