Patent number: 11766899Abstract: A pneumatic vehicle tire including a utility vehicle tire has a tread with profile positives which are separated from one another in a circumferential direction by transverse channels which extend continuously from the central region of the tread as far as the lateral tread edges, respectively. The transverse channels are main channels of the tread and, at least over the major part of the course thereof, have the maximum provided profile depth. The transverse channels are provided, on the respective channel base thereof, with a row of base elevations formed so as to be distributed over the entire course of the transverse channels. The base elevations are attached to the channel flanks of the transverse channels and are configured such that their rubber volume becomes smaller the closer to the tread edge they are disposed.Type: GrantFiled: June 15, 2018Date of Patent: September 26, 2023Assignee: Continental Reifen Deutschland GmbHInventors: Florian Kristen, Andreas Haertwig, Chun Yi Yeo
