摘要： A heavy duty tire comprises: a carcass ply of cords extending between bead portions; and a bead reinforcing layer disposed in each of the bead portion. The carcass ply has edges winded around the bead cores so that the winded portion has a base part extending along the bead core from the axially inside to the axially outside thereof, and a radially outer part extending axially inwards on the radially outside of the bead core. The bead reinforcing layer comprises: a curved portion extending along the base part; an axially outer portion extending radially outwardly, separation from the base part; and an axially inner portion extending radially outwardly along a main portion of the carcass ply. The bead reinforcing layer is composed of a ply of cords laid side by side, and the spacing Da of the cords in an axially outer part beneath the bead core, of the curved portion is not less than 1.5 times and not more than 3.0 times the spacing Db of the cords in the axially outer portion.

摘要： A tire 2 has a belt 14 and a hard rubber layer 16. The belt 14 has a first ply 26, a second ply 28, a third ply 30 and a fourth ply 32. A width W3 of the third ply 30 is smaller than a width W1 of the first ply 26 and a width W2 of the second ply 28, and 75% of a width of a tread. Each of the plies 26, 28, 30, 32 has a steel cord. The first ply 26 and the second ply 28 construct a cross-ply structure. A cord of the third ply 30 is wound spirally. The third ply 30 has what is referred to as a jointless structure. The hard rubber layer 16 is positioned between the first ply 26 and the second ply 28, and outward of the third ply 30 in an axial direction. A complex elastic modulus of the hard rubber layer 16 is equal to or greater than 30 MPa.
