A tire for mounting on a rim, the flanges of which have rounded rim hooks, has at least two beads and a carcass reinforcement formed of at least one ply of reinforcement elements. Each bead is devoid of a bead wire. The carcass reinforcement has in each bead a meridian profile which is curved axially and radially from the outside to the inside to form an axially inner edge located at an angle open axially and radially towards the inside. The carcass reinforcement is reinforced in each bead at least radially to the outside and axially to the inside, firstly by at least one first continuous additional layer, formed of inextensible circumferential reinforcement elements and secondly by at least one second continuous additional layer, formed of inextensible, radial reinforcement elements the two additional layers having meridian profiles substantially parallel to the meridian profile of the carcass reinforcement in the bead. |
