The invention relates to a tyre (1) in which each bead (3) has notches (5) of thickness "T" arranged at a circumferential pitch "P", said notches (5) extending substantially perpendicularly to the contact surface (30) to a depth "D" greater than 3 mm, said notches extending radially from a radially inner limit (51) and a radially outer limit (52), the curvilinear length between the radially inner limit (51) and the radially outer limit (52) being "H", an intermediate point (50) being, in a meridian section of the tyre mounted on a rim, inflated to nominal pressure and loaded at twice its nominal load-bearing capacity, situated at half the curvilinear distance between the long contact point (50a) with the rim at a first azimuth corresponding to the centre of the contact patch (20) of the tyre (1) with the ground and the short contact point (50b) with the rim at a second azimuth situated 180° from the first azimuth (A1), the curvilinear length between the long contact point (50a) and the short contact point (50b) being "HB", said radially inner limit (51) being situated radially towards the inside with respect to said intermediate point (50) by a value "H1" with H1=HB/2+B, where B is between 125% of the pitch P and 250% of the pitch P, as far as a radially outer limit (52) situated radially above the intermediate point (50) by a value "H2" with H2=HB/2+B, the pitch P being between 0.8*H and 2.5*H and H=H1+H2.
