VEHICLE PNEUMATIC TYRES HAVING A MULTI-PART CORE PROFILE, AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to vehicle pneumatic tyres comprising a tyre bead (1) provided with a core (3) and a core profile (2), said core profile (2) consisting of at least three core profiled parts (5, 6, 7) that form an essentially wedge-shaped cross-sectional profile when assembled. The inner profiled part (5) arranged in relation to the inner side (4) of the tyre forms a first profiled part, and the central profiled part (6) and the outer profiled part (7) form a second profiled part. The outer profiled part (7) and the inner profiled part (5) have a shore hardness of between 58 and 68, and the central profiled part has a shore hardness of between 81 and 91.
