Title (EN) TIRE FOR TWO-WHEELED VEHICLE
(FR) PNEU POUR VÉHICULE À DEUX ROUES
(JA) 二輪車用タイヤ
Abstract:
(EN) This tire for a two-wheeled vehicle is provided with a pair of bead parts and a pair of side wall parts, and a tread part that is continuous with the side wall parts. The tread part is divided into three by a center part and a shoulder part. The tread rubber of the center part and the tread rubber of the shoulder part both contain a rubber component and satisfy formula (1) below. It is possible for this tire for a two-wheeled vehicle to be wear-resistant and to have the tread exhibit a wet grip property. (Dynamic elastic modulus E' of tread rubber of center part at 0°C / dynamic elastic modulus E' of tread rubber of shoulder part at 0°C) < 0.7 (1)
(FR) Le pneu pour un véhicule à deux roues selon l'invention est pourvu d'une paire de parties talon et d'une paire de parties paroi latérale, et d'une partie bande de roulement qui est continue avec les parties paroi latérale. La partie bande de roulement est divisée en trois par une partie centrale et une partie épaulement. Le caoutchouc de bande de roulement de la partie centrale et le caoutchouc de bande de roulement de la partie épaulement contiennent tous deux un constituant de caoutchouc et satisfont la formule (1) ci-dessous. Il est possible que ce pneu pour un véhicule à deux roues selon l'invention soit résistant à l'usure et que sa bande de roulement possède une propriété d'adhérence sur sol mouillé. (Module élastique dynamique E' du caoutchouc de bande de roulement de la partie centrale à 0 °C / module élastique dynamique E' du caoutchouc de bande de roulement de la partie épaulement à 0 °C) < 0,7 (1)
(JA) 本発明の二輪車用タイヤは、一対のビード部及び一対のサイドウォール部と、両サイドウォール部に連なるトレッド部とを備え、該トレッド部がセンター部とショルダー部とによって3分割され、前記センター部のトレッドゴム及び前記ショルダー部のトレッドゴムは共にゴム成分を含有し、かつ、下記式(1)を満たす。本発明の二輪車用タイヤは、トレッドのウェットグリップ性及び耐摩耗性を両立することができる。 (センター部のトレッドゴムの0℃での動的弾性率E'/ショルダー部のトレッドゴムの0℃での動的弾性率E')<0.7 (1)
