Abstract
(EN)
A pneumatic tire is provided which, while ensuring runflat durability, makes it possible to achieve, in a balanced manner, a high degree of both ride comfort during normal driving and steering stability. In this pneumatic tire, a side reinforcement layer 9 with a crescent-shape cross section is provided inside of a carcass layer 4 in the tire width direction in a side wall section 2, and as the carcass cords constituting the carcass layer 4, organic fiber cord is used that has a 4.3-6.0% elongation under a 1.5 cN/dtex load, and a total fineness of 4000-6000 dtex.
(FR)
L'invention concerne un pneumatique qui, tout en assurant une durabilité de roulage à plat, permet d'obtenir, de manière équilibrée, un degré élevé en matière de confort de conduite en conduite normale et de stabilité de direction. Dans ce pneumatique, une couche de renforcement latéral (9) ayant une section transversale en croissant est disposée à l'intérieur d'une couche de carcasse (4) dans le sens de la largeur du pneu dans une section paroi latérale (2), et en tant que câbles de carcasse constituant la couche de carcasse (4), un câble de fibre organique est utilisé présentant un allongement de 4,3 à 6,0 % sous une charge de 1,5 cN/dtex, et une finesse totale de 4 000 à 6 000 dtex.
