Tire (10) comprising a tread (40) divided, by the median plane (130) of the tire, into a first semi-tread (41) which extends axially from said median plane toward a first axial edge (45) of the tread, the first semi-tread comprising a first main circumferential groove (141) opening onto the rolling surface, and a second semi-tread (42) which extends axially from said median plane toward a second axial edge (46) of the tread, the tire further comprising an additional stiffening reinforcement (151) comprising a plurality of substantially radially directed thread-like reinforcing elements, this additional stiffening reinforcement being situated radially on the inside of the carcass reinforcement and in direct radial alignment with said first main circumferential groove, the additional stiffening reinforcement (151) extending axially on each side of the first main circumferential groove (141) over an axial distance less than or equal to 75% of the axial distance separating the first main circumferential groove (141) from any other circumferential groove of the tread or, as appropriate, from the axial edges (45, 46) of the tread.
