PNEUMATIC TYRE COMPRISING REINFORCING ELEMENTS IN THE FORM OF MULTI-LAYER TAPES

摘要

The invention relates to a pneumatic tyre (1) comprising a carcass ply (2) connecting two beads (5) via two sidewalls (3), a crown reinforcing area (10) being mounted on said carcass ply (2) radially on the outside, which reinforcing area comprises a plurality of reinforcing tapes (12, 14) arranged in at least two layers and coated with an elastomer composition (13, 15), the average overlap between the tapes of the two layers being greater than 40%, and the reinforcing tapes (12, 14) being made of a thermoplastic film having a modulus greater than 0.9 GPa, preferably more than 2 GPa, in the main direction and in the transverse direction.
