摘要： A pneumatic tire (10), which has, in the surface of the tread (11), lug grooves (15) on one side extending from one axial edge towards the axial center of the tire in such a manner as to intersect with the circumferential direction of the tire and lug grooves (15) on the other side extending in a symmetrically opposite direction from the axial center towards the other axial edge of the tire, has at least one circumferential groove (12) extending circumferentially around the tire. Also, circumferential grooves (12, 13a, 13b) are so formed as to satisfy a relationship of "1 ≦ (S/L) ≦ 3" where L is the axial length of the central region, which is the region enclosed by two straight parallel lines each passing through the center between the contact width center (CL) and the contact edge with the shoulder regions being the regions axially outside of the parallel lines, and S is the total of the groove areas of the circumferential grooves (12, 13a, 13b) disposed in the central region. Therefore, the pneumatic tire (10) not only secures the steering stability performance on wet road surfaces, but also improves the steering stability and wear resistance performance on dry road surfaces.

摘要： A resin-covered cord including n number of individual cords, disposed so as to be mutually spaced apart from each other, a covering resin that covers the cords, and an adhesive resin that is disposed between the cords and the covering resin and that has a greater tensile elastic modulus than the covering resin. Equation (1) below is satisfied, in which A is a total value of a width direction dimension of a portion where the cords and the adhesive resin are disposed, and B is a maximum value of a thickness direction dimension. B A / n n ≥ 1

摘要： A tire having V-shaped lug grooves displays both improved grip performance on snow and anti-hydroplaning performance. To that end, an absolute value of difference between a lug groove diagonal angle ( ¸ LG ), which is an angle of diagonal lug grooves (13) in a tread (11) surface with respect to a tire axial direction, and a profile line diagonal angle ( ¸ FP ), which is an angle of a normal line of a leading-end profile line of a contact patch shape of the tire (10) with respect to the tire axial direction, is set to 0° or more and 60° or less at respective positions in the tire axial direction. And diagonal lug grooves (13) are formed such that absolute values of difference in a center portion, which is defined to be 20% in width of a contact patch width (W) with an equatorial plane at a center, and an intermediate portion, which is defined to be 20% of the contact patch width (W) on each axially outer side adjacent to the center portion, are larger than an absolute value of difference in a shoulder portion, which is defined to be 20% of the contact patch width (W) on each axially outer side adjacent to the intermediate portion.

摘要： By forming a ground contact edge side of lug grooves (16) such that the groove depth becomes shallower in groove depth from the tire equatorial plane side toward the ground contact edge, and by setting an average angle of inclination (θ1) formed between a tread face (12A) and a groove bottom (16B) to be not more than 5°, water expulsion is performed smoothly in the vicinity of the ground contact edge while securing the rigidity of land portions in the vicinity of the ground contact edge. This enables a high degree of both wet performance and dry performance to be achieved.
