Abstract
A tire includes a carcass ply, two beads, two sidewalls, and a crown reinforcing zone. The carcass ply connects the two beads by way of the two sidewalls. The crown reinforcing zone is positioned radially external to the carcass ply. The crown reinforcing zone includes a plurality of reinforcing strips disposed in at least two layers. The reinforcing strips are coated in an elastomeric composition. A mean overlap between the reinforcing strips of the two layers is greater than 40%. The reinforcing strips are made of a thermoplastic film having a modulus greater than 0.9 GPa, and preferably greater than 2 GPa, in a main direction and in a transverse direction.
