Definitions

  • a plurality of outer blocks that are divided into the circumferential narrow groove, the tire ground contact edge, and the plurality of outer lug grooves, and the inner block and the outer block are centered on the circumferential narrow groove. It is arranged in a staggered manner in the tire circumferential direction.
  • the belt cover 143 is formed by rolling a plurality of belt cords made of steel or organic fiber material coated with a coat rubber, and has a belt angle of 45 [deg] or more and 70 [deg] or less in absolute value. Further, the belt cover 143 is disposed so as to be laminated on the outer side in the tire radial direction of the cross belts 141 and 142.
  • the circumferential narrow groove 23 is a narrow groove extending in the tire circumferential direction (see FIGS. 2 and 3).
  • the circumferential narrow groove 23 is disposed in the ground contact surface of the shoulder land portion 33. Further, the circumferential narrow groove 23 may have a straight shape, or may have a bent shape or a wavy shape.
  • the groove width W2 of the circumferential narrow groove 23, the groove width W3 of the inner lug groove 43, and the groove width W4 of the outer lug groove 44 are 0.10 ⁇ W2 / W3 ⁇ 0.50 and 0. It is preferable to have a relationship of 10 ⁇ W2 / W4 ⁇ 0.50.
  • the edge portion of the block of the center land portion 32 partitioned by the outermost circumferential main groove 22 has a step shape corresponding to the edge portion of the inner block 331 of the shoulder land portion 33.
  • the edge part on the outermost circumferential direction main groove 22 side of the block of the center land part 32 has a step shape having two steps. Further, these steps have a linear shape substantially parallel to the tire circumferential direction on the block tread surface, and are arranged offset from each other in the tire width direction.
  • the phase of the step shape is synchronized so that the edge portion of the block of the center land portion 32 and the edge portion of the inner block 331 of the shoulder land portion 33 have a constant groove width of the outermost circumferential main groove 22.
  • the outermost circumferential main groove 22 extends in the tire circumferential direction with a constant groove width while being bent in a step shape in the tire width direction.
  • the groove width W2 of the circumferential narrow groove 23, the groove width W3 of the inner lug groove 43, and the groove width W4 of the outer lug groove 44 are 0.10 ⁇ W2 / W3 ⁇ 0. 50 and 0.10 ⁇ W2 / W4 ⁇ 0.50 (see FIG. 3).
  • the groove width W2 of the circumferential direction fine groove 23 is optimized. That is, when the lower limit of the groove width W2 of the circumferential narrow groove 23 is within the above range, the effect of improving the performance on ice and snow by the circumferential narrow groove 23 is appropriately ensured.
  • the distance Ls from the tire equatorial plane CL to the circumferential narrow groove 23 and the distance L from the tire equatorial plane CL to the tire ground contact edge T are 0.70 ⁇ Ls / L ⁇ 0. .90 (see FIG. 2).
  • the position of the tire width direction of the circumferential direction narrow groove 23 is optimized.
  • the circumferential narrow grooves 23 can be disposed in the ground contact surface even when the tire ground contact width is small when the vehicle is empty. Thereby, the function of the circumferential narrow groove 23 can be appropriately ensured regardless of the loading condition of the vehicle.

Abstract

L'invention porte sur un pneu (1) qui est configuré de telle manière que des zones d'épaulement (33) comportent chacune : une rainure étroite périphérique, unique (23), s'étendant dans la direction périphérique du pneu ; des rainures d'étrier internes (43) s'étendant vers l'intérieur dans la direction de la largeur du pneu à partir de la rainure étroite périphérique (23), et ouvertes vers une rainure principale périphérique située le plus à l'extérieur (22) ; des rainures d'étrier externes (44) s'étendant vers l'extérieur dans la direction de la largeur du pneu à partir de la rainure étroite périphérique (23) et atteignant l'extrémité de contact avec le sol (T) du pneu ; des blocs internes (331) définis par la rainure principale périphérique située le plus à l'extérieur (22), la rainure étroite périphérique (23) et les rainures d'étrier internes (43) ; des blocs externes (332) délimités par la rainure étroite périphérique (23), l'extrémité de contact avec le sol (T) du pneu et les rainures d'étrier externes (44). Les blocs internes (331) et les blocs externes (332) sont disposés selon un motif en zigzag dans la direction périphérique du pneu des deux côtés de la rainure étroite périphérique (23).
