Abstract:
(EN)
A tread (16) is provided with a plurality of circumferential main grooves that extend in the circumferential direction of the tire, and a first rib (34) and a second rib (38) are formed between the plurality of circumferential main grooves. The first rib (34) and the second rib (38) are respectively provided with first arc surfaces (34A-1R, 38A-1R) having arc-like forms that have the centers within the ribs. In addition, the first rib (34) and the second rib (38) are also provided with second arc surfaces (34A-2R, 38A-2R) that are respectively formed to be continued to the first arc surfaces (34A-1R, 38A-1R) and have curvature radii smaller than those of the first arc surfaces (34A-1R, 38A-1R).
(FR)
L'invention concerne une bande de roulement (16) dotée d'une pluralité de rainures principales circonférentielles qui s'étendent dans la direction circonférentielle du pneu, et une première nervure (34) et une seconde nervure (38) sont formées entre la pluralité de rainures principales circonférentielles. La première nervure (34) et la seconde nervure (38) sont respectivement dotées de premières surfaces arquées (34A-1R, 38A-1R) présentant des formes arquées dont les centres sont situés dans les nervures. En outre, la première nervure (34) et la seconde nervure (38) sont également dotées de secondes surfaces arquées (34A-2R, 38A-2R) qui sont respectivement formées de manière à être continues avec les premières surfaces arquées (34A-1R, 38A-1R) et qui présentent des rayons de courbure inférieurs à ceux des premières surfaces arquées (34A-1R, 38A-1R).
