<p>The pneumatic vehicle tyre of radial type for passenger car, comprises a profiled tread rubber (1), a multiply belt assembly (2), an inner layer (4), monolayered carcass (3) that is led around bead cores, and bead profile in bead regions (5) and which is incorporated in the region of side walls. A cross-sectionally crescent-shaped reinforcing profile is extended over a large part of the length of the sidewall and is formed from a mixture of vulcanized rubber. The bead profile on the same rubber mixture is same like the crescent-shaped reinforcing profile.

The bead profile on the same rubber mixture is same like the crescent-shaped reinforcing profile. The rubber mixture of the reinforcing profile that has a shape of crescent in cross-section, contains 50-90 phr of low-hysteresis soot with iodine adsorption number of less than 100 g/kg and is networked with sulfur of 2-6 phr.</p> |
