Abstract
(EN)
This pneumatic tire 1 is equipped with: at least four circumferential principal grooves 21, 22 that extend in the circumferential direction of the tire; and at least five rows of land sections 31-33 which are delimited by the circumferential principal grooves 21, 22, and which include a center land section 31, a pair of second land sections 32, 32, and a pair of shoulder land sections 33, 33. Moreover, at least one row of the second land section 32 is equipped with a plurality of lug grooves 421, 422 and a plurality of blocks 321, 322 delimited by the plurality of lug grooves 421, 422. In addition, each of the plurality of blocks 321, 322 has one circumferential narrow groove 323, 324 that passes through the block 321, 322 in the circumferential direction of the tire.

L'invention concerne un bandage pneumatique (1) qui comprend : au moins quatre rainures principales circonférentielles (21, 22) qui s'étendent dans la direction circonférentielle du pneu ; et au moins cinq rangées de sections d'appui (31 à 33) qui sont délimitées par les rainures principales circonférentielles (21, 22) et qui comprennent une section d'appui centrale (31), une paire de secondes sections d'appui (32, 32) et une paire de sections d'appui d'épaulement (33, 33). En outre, au moins une rangée de la seconde section d'appui (32) comporte de multiples rainures de barrette (421, 422) et de multiples blocs (321, 322) délimités par les multiples rainures de barrette (421, 422). De plus, chaque bloc de la pluralité de blocs (321, 322) comporte une rainure étroite circonférentielle (323, 324) qui passe à travers le bloc (321, 322) dans la direction circonférentielle du pneu.
