(JA) 空気入りタイヤ
Abstract
(EN) A pneumatic tire that improves, in a balanced manner, driving stability, road noise, ride comfort, and fuel consumption characteristics. In the pneumatic tire, when viewed in a meridian section, a bead filler is larger than a triangle formed by connecting a top and a bottom side, and a sheet-like auxiliary filler is disposed from a side wall portion to a bead portion. The auxiliary filler has a thickness of 0.5 to 2.0 mm and is formed from a harder material than a rubber composition, excluding the bead filler, adjacent to the auxiliary filler. The top (D) of the bead filler is at a position lower than the point B1 and higher than a rim flange by 5 mm or more. The lower end (C1) of the auxiliary filler is at a position higher than the point A1 and lower than the point E2. The upper end (C2) of the auxiliary filler is at a position lower than the point A2, away from the point A2 by 10 mm or more, and higher than the point B2.
(FR) L'invention concerne un pneu qui améliore, de manière équilibrée, la stabilité de la conduite, le bruit de la route, le confort du roulement et les caractéristiques de consommation de carburant. Dans ce pneu, lorsqu'il est vu en coupe méridienne, un bourrage sur tringle est plus grand qu'un triangle formé par la connexion d'un côté supérieur et d'un côté inférieur et un bourrage auxiliaire en feuille est disposé entre une partie de paroi latérale et une partie talon. Le bourrage auxiliaire, qui présente une épaisseur de 0,5 à 2,0 mm, est constitué d'un matériau plus dur qu'une composition de caoutchouc, à l'exclusion du bourrage sur tringle, adjacent au bourrage auxiliaire. Le sommet (D) du bourrage sur tringle est situé sur une position plus basse que le point B1 et plus haute qu'un bord de jante de 5 mm ou plus. L'extrémité inférieure (C1) du bourrage auxiliaire est située sur une position plus haute que le point A1 et plus basse que le point E2. L'extrémité supérieure (C2) du bourrage auxiliaire est située sur une position plus basse que le point A2, éloignée du point A2 de 10mm ou plus, et plus haute que le point B2.
(JA)  操縦安定性、ロードノイズ、乗心地、燃費性能をバランス良く改善した空気入りタイヤである。この空気入りタイヤは、ビードフィラーを子午線断面視で底辺と頂点とを結んだ三角形よりも太くし、サイドウォール部からビード部にかけて厚さが0.5~2.0mmであってビードフィラー以外の隣接するゴム組成物よりも硬い材料からなるシート状の補助フィラーを配置したものである。ビードフィラーの頂点Dが点B1より低く且つリムフランジより5mm以上高い位置にあり、補助フィラーの下端C1が点A1より高く且つ点E2より低い位置にあり、補助フィラーの上端C2が点A2より低く且つ点A2から10mm以上離れると共に点B2より高い位置にある。
