摘要： A pneumatic tire comprising a tread divided into at least three ribs by at least two main wide grooves extending substantially in a circumferential direction of the tire, wherein a shoulder rib arranged at an outermost end portion of the tread is divided in an axial direction parallel to an axis of rotation of the tire into at least two shoulder rib portions; and between two adjacent shoulder rib portions of said at least two shoulder rib portions, an outer surface of an outer shoulder rib portion is radially inwardly disposed with respect to an extension line of an outer surface of an inner shoulder rib portion arranged inwardly of the outer rib portion. A plurality of sipes may be formed in the vicinity of an outer end of at least one shoulder rib portion other than an outermost shoulder rib portion. Further, a plurality of sipes are formed in the vicinities of outer ends of at least two rib portions other than an outermost rib portion, the quantity of siping being gradually reduced in the axial direction.

摘要： A novel tread pattern is disclosed, which can give high performances on wet road at both the straight running and the cornering under a low load, particularly no load, to a heavy duty pneumatic radial tire without sacrificing the performances on wet road under normal load. The tread pattern comprises at least 4 lands defined by at least 3 main grooves, wherein a pair of first group lands arranged on the outermost side regions of the tread have substantially continuous along the the circumferential direction of the tread and the remaining lands located between the first group lands have notches arranged thereon in their lateral direction.

摘要： A pneumatic radial tire having an improved bead portion reinforcing construction is disclosed. The radial tire comprises a bead portion reinforcing band disposed along the bead portion formed by folding the ply of the carcass body around the bead ring. The bead portion reinforcing band comprises at least one chipper layer. The chipper is composed of a reinforcing element embedded in rubber and formed of 1 to 50 helically formed filaments. The reinforcing element has a modulus of elasticity of 0.029.times.10.sup.4 kg/mm.sup.2 to 1.60.times.10.sup.4 kg/mm.sup.2 and is inclined at a given angle with respect to the ply cords of the carcass body so as to make the chipper as a whole extensible and rigid.
