1. A tyre comprising:
a body ply, which is at least partially turned-up; two beads arranged on opposite sides of the body ply and surrounded by the body ply; a tread supported by the body ply; two sidewalls arranged outside the body ply between the tread and the beads; and two abrasion gum strips, each arranged externally below a respective sidewall of said two sidewalls and at a respective bead of said two beads, wherein, between each of said two sidewalls and the respective abrasion gum strip, a joining surface is defined, which joining surface extends, in cross section, between an axially outer first end and an axially inner second end,wherein each joining surface, in cross-section, has a “U”-like shape.
