    Abstract: Technique for improving the endurance of beads of a radial tire for a heavy vehicle of the civil engineering type, by blocking the cracks that are initiated in the carcass reinforcement upturn end zone and that are propagated in the surrounding polymer materials, causing the deterioration of the bead over time. A binding element (23), having at least two layers of binding including reinforcement elements made of textile material, is in continuous contact with the carcass reinforcement upturn (211) between a first point of contact (A2) on the axially inner face (211a) of carcass reinforcement upturn, corresponding to a first end (I2) of the binding element, and a last point of contact (B2) on the axially outer face (211b) of the carcass reinforcement upturn.

    Abstract: In an apex 34 of a tire 2, a reinforcing portion 48 is located inward of a main body 46 in an axial direction. When a position on an outer surface of the tire 2 at which position a height from a BBL is 14 mm is defined as a first point P1 and a position on the outer surface of the tire 2 at which position a height from the BBL is 20 mm is defined as a second point P2, the reinforcing portion 48 overlaps the first point P1 and the second point P2 in a radial direction. A loss tangent of the reinforcing portion 48 is equal to a loss tangent of the main body 46 or less than the loss tangent. A hardness of the reinforcing portion 48 is equal to a hardness of the main body 46 or greater than the hardness.

    Abstract: A pneumatic tire comprises: a carcass ply extending between bead portions and including a topping rubber layer, the topping rubber layer facing the inside of the tire and made of a butyl rubber compound containing at least 10 parts by weight of butyl rubber or butyl rubber derivative; and a belt disposed radially outside the carcass in the tread portion, the belt comprising at least one ply of monofilament cords laid at an angle of from 10 to 40 degrees with respect to the circumferential direction of the tire, and each of the monofilament cord consisting of a single filament. The belt further comprises one ply of multifilament cords or one ply of monofilament cords. The height of a bead apex, which is disposed between a carcass ply turnup portion and main portion in each bead portion, can be reduced into a range of from 10 to 20 mm, and in this case, the carcass ply turnup portion is extended radially outwardly beyond the radially outer end of the bead apex so as to adjoin the carcass ply main portion.
