A pneumatic vehicle tire of a radial type of construction with a profiled tread (), sidewalls (), bead regions () and an airtight inner layer (), which forms the inner side () facing the interior space of the pneumatic vehicle tire, ribs () being formed on the inner layer (), having been imprinted in it by a heating bladder introduced into the interior of the tire during the vulcanizing of the pneumatic vehicle tire in a tire heating mold, and a sound absorber () being provided so as to extend in an annular manner on a circumferential region () of the inner side () opposite from the tread (). Grooves () have been formed by the heating bladder at least in a partial region of the circumferential region () of the inner layer () on which the sound absorber () is provided.

Pneumatic vehicle tire

A pneumatic vehicle tire () having a profiled tread () that merges at either side into sidewalls (), the end of which is formed by a tire bead () insertable in an airtight manner into a wheel rim () of a vehicle wheel (), wherein an absorber () has been integrated into the pneumatic vehicle tire () for sound absorption and the cohesive bond consists of an adhesion promoter () applied between the absorber () and the inner surface () of the pneumatic vehicle tire (), has been further developed in accordance with the invention in that the inner surface () of the pneumatic vehicle tire () has mutually alternating adhesion promoter sections () and adhesion promoter-free sections (), the adhesion promoter-free sections () having been coated with a separating agent ().

Pneumatic vehicle tyres

The invention relates to a pneumatic vehicle tire with a material ring () inside it, adhesively attached to the inner surface opposite from the tread (), the material ring () adhering to a self-sealing sealant (), which at least immediately after its application has a tackiness required for the adhesive attachment of the material ring (). To improve the sealing effect, the material ring () arranged on the sealant () is closed-cell and airtight.

The invention relates to a pneumatic vehicle tyre with a sound-absorbing inner absorber () adhesively attached in its interior to the inner surface () opposite from the tread (), wherein the inner absorber () adheres to an automatically sealing sealant (), which at least immediately after being applied has the tackiness required for the adhesive attachment. In order not to influence the flow properties of the sealant disadvantageously and in order to ensure a reliable sealing effect of the sealant, a separating layer () is arranged between the sealant () and the inner absorber () and the separating layer () is made in such a way as to ensure a sufficient flowability of the sealant () for the sealing and a reliable adhesive attachment of the foam ring ().
