摘要： A pneumatic radial tire for heavy vehicles is disclosed. This tire comprises a carcass composed of at least one ply of cords arranged in a substantially radial plane inclusive of the rotary axis of the tire with a turnup portion thereof, and a plurality of reinforcing layers for bead portion each containing cords crossed with the cords of the carcass ply. Among these reinforcing layers, reinforcing layers having heights which are different in radially upward end as measured from a reference line parallel to the rotary axis of the tire passing through the center of a bead core toward the radial direction of the tire and having cords with substantially the same modulus of elasticity are crossed with each other such that the cords of the reinforcing layer are inclined at a larger angle with respect to the radial plane of the tire as the height of the radially upward end becomes lower.

摘要： A heavy duty pneumatic tire includes a tread surface divided along circumferential directions by at least two zigzag tread grooves to form a plurality of circumferential zigzag ribs whose at least one side edge is formed with a plurality of narrow cuts opening into the tread grooves and substantially in parallel with an axial direction of the tire. According to the invention, lengths and/or depths of the narrow cuts are gradually reduced from the cuts in the extending corners to the cuts in the retracting corners of the ribs, or the narrow cuts are inclined relative to radial surfaces of the tire passing through openings of the cuts to make angles with their radial surfaces, the angles being progressively larger as the cuts are nearer the extending corners to mitigate railway wear of the tire without sacrificing other wear-resistant properties.
