摘要

The tire has an apex (1) arranged coaxially around a bead core (2) and comprising a triangular profile in a cross-section. The apex is centrally arranged in a tire bead, where the apex comprises two outer sides along axial direction. The apex comprises a set of relief grooves (3) on one of the two outer sides, where the grooves are evenly distributed over circumference of the tire in the form of recesses. The apex in a region of the relief grooves in the cross-section is reduced, where the grooves are arranged along radial direction only in a portion of the outer sides. The apex is made of an elastomeric material.
