A pneumatic tire having an improved uniformity at tire-wheel assembled state comprises a bead portion closely fitted to a standard rim comprising a slant bead seat, a rounded concave corner portion extending from the slant bead seat and a flange protrusively extending outward from the rounded concave corner portion with a curved portion. In this tire, the bead portion has an expanded heel bringing about close fitting to the rounded concave corner portion prior to a contact between the curved portion and the bead portion.
La présente invention se rapporte à un pneu présentant une uniformité améliorée au niveau de l'assemblage par utilisation d'un talon dont la configuration permet un ajustage serré à une jante standard comportant un siège de talon à profil incliné, une partie concave arrondie depuis le siège de talon, et une joue avec bord recourbé en prolongement du coin concave arrondi. La partie talon de ce pneu comporte une région aplatie qui assure un ajustement serré à la partie concave arrondie avant contact avec le bord recourbé et le talon.
