Abstract
(EN)
This pneumatic tire comprises: a carcass that has a carcass ply which extends from one bead part to the other bead part, and which is configured by covering a plurality of cords with a coating rubber; a belt which is arranged on the outside of the carcass in the tire radial direction, and which contains a resin layer that is formed from a resin that has a higher tensile elastic modulus than the coating rubber; and a belt protection layer which is bonded to the surface of the resin layer, and which is formed from a material that has a higher tensile elastic modulus than the coating rubber.
(FR)
La présente invention concerne un pneumatique comprenant : une carcasse qui a une nappe de carcasse qui s'étend d'une partie de talon à l'autre partie de talon et qui est configurée en recouvrant une pluralité de cordons avec un caoutchouc de revêtement ; une ceinture qui est disposée sur l'extérieur de la carcasse dans la direction radiale du pneumatique et qui contient une couche de résine qui est formée à partir d'une résine qui a un module d'élasticité en traction supérieur à celui du caoutchouc de revêtement ; et une couche de protection de ceinture qui est liée à la surface de la couche de résine et qui est formée à partir d'un matériau qui a un module d'élasticité à la traction supérieur à celui du caoutchouc de revêtement.
(JA)
空気入りタイヤは、一方のビード部から他方のビード部に跨り、複数本のコードがコーティングゴムで被覆されて構成されたカーカスプライを有するカーカスと、カーカスのタイヤ径方向外側に配置されコーティングゴムよりも引張弾性率の高い樹脂で形成された樹脂層を含むベルトと、樹脂層の表面に接合され、コーティングゴムよりも引張弾性率の高い材料で形成されたベルト保護層と、有する。
