Title (EN) PNEUMATIC TIRE
(FR) PNEUMATIQUE
(JA) 空気入りタイヤ
Abstract:
(EN) Provided is a pneumatic tire (1) for reducing running noise in a low-temperature environment, wherein a noise damper (20) composed of a porous material is fixed to a tire inner cavity surface (16) of a tread part (2). In an atmosphere of -60˚C, the hardness of the noise damper (20) at 25% compressive load, as measured in accordance with JISK6400-2, is 110 kPa or less.
(FR) L'invention concerne un pneumatique (1) destiné à réduire le bruit de roulement dans un environnement à basse température, un atténuateur de bruit (20) composé d'un matériau poreux étant fixé à une surface de cavité interne (16) d'une partie de bande de roulement (2) du pneumatique. Dans une atmosphère de -60 °C, la dureté de l'atténuateur de bruit (20) à une charge de compression de 25 %, mesurée conformément à la norme JISK6400-2, est égale ou inférieure à 110 kPa.
(JA) 低温環境下において走行ノイズを低減する空気入りタイヤ(1)は、トレッド部(2)のタイヤ内腔面(16)に、多孔質材料からなる制音体(20)が固着されている。制音体(20)は、-60℃の雰囲気において、JISK6400-2に準じて測定される25%圧縮荷重時の硬度が110kPa以下である。
