    Abstract: A crown portion of a pneumatic tire comprising at least one radial carcass ply and a belt of at least two cross belt layers (1) is reinforced by arranging between the carcass ply and the belt a crown reinforcing layer (3) containing wavy or zigzag-like cords or filaments arranged substantially parallel with the equatorial plane of the tire.

    Abstract: A heavy duty radial tire includes at least one radial carcass extending from one bead portion to the other bead portion and using inextensible cords and a belt arranged outwardly of the radial carcass for reinforcing a tread of the tire. The tire comprises, during expanding of the tire from 5% to 100% of a normal inner pressure, a first profile portion (5) expanding radially outwardly in a tread zone, a second profile portion (7) depressing axially inwardly of the tire in a radially outer zone of a sidewall from one end (4) of said tread to a tire maximum width position (6) when filled with the normal inner pressure, and a third profile portion (9) expanding axially outwardly of the tire in a radially inner zone of the sidewall from the tire maximum width position (6) when filled with the normal inner pressure to a parting point (8) of the sidewall from the rim, thereby properly distributing strains occurring in the tire in filling with the normal inner pressure. Moreover, a carcass profile in the radial cross-section of the tire filled with an inner pressure 5% of the normal inner pressure and under no load condition is a composite curve smoothly passing through points R, A and G, and the carcass profile fulfills three relations relative to a maximum distance H of the carcass line C from the bead base line RL with respect to maximum distance deviated from an equilibrium configuration curve N.

Moreover, a carcass profile in the radial cross-sections of the tire filled with an inner pressure 5% of the normal inner pressure and under no load condition is a composite curve smoothly passing through points B, A and D, where the point A is an intersection of a carcass line C of the carcass profile and a tangent mm' in a radial direction to the carcass line at a carcass line maximum width position and the points B and C are intersections of the carcass line C and a perpendicular pp' to a bead based line RL, the perpendicular pp' spaced apart from an equatorial plane M of the tire by a distance of 0.45 times a rim width, and the carcass profile fulfills three relations relative to a maximum distance H of the carcass line C from the bead base line RL with respect to maximum distance deviated from an equilibrium configuration curve N.
