Abstract
(EN)
In a cross section along a tire width direction and a tire radial direction, when a position on a tire equatorial plane in a tread portion (20) is taken as a point A, an imaginary straight line passing through the point A and parallel to the tire width direction as L1, an end portion outside a belt (50a) in the tire width direction as a point J, the belt (50a) being provided at an outermost part of a belt layer (50) in the tire radial direction, an imaginary straight line passing through the point J and parallel to the tire radial direction as L10, a point of intersection between the imaginary straight line L1 and the imaginary straight line L10 as a point N, the distance between the point A and the point N as X, the distance between the point N and the point J as Y, an imaginary perpendicular line perpendicular to a tire outer surface as L11, and a point of intersection between the imaginary perpendicular line L11 and the tire outer surface as a point K, the distance U between the point J and the point K is 2 to 10 mm. The ratio Y/X between the distance Y and the distance X is 0.03 to 0.25.

Dans une section transversale le long d'une direction de largeur de pneu et d'une direction radiale de pneu, lorsqu'une position sur un plan équatorial de pneu dans une partie bande de roulement (20) est prise en tant que point A, une ligne droite imaginaire passant à travers le point A et parallèle à la direction de largeur du pneu en tant que L1, une partie extrémité à l'extérieur d'une ceinture (50a) dans la direction de la largeur du pneu en tant que point J, la ceinture (50a) étant disposée au niveau d'une partie la plus à l'extérieur d'une couche de ceinture (50) dans la direction radiale du pneu, une ligne droite imaginaire passant à travers le point J et parallèle à la direction radiale du pneu en tant que L10, un point d'intersection entre la ligne droite imaginaire L1 et la ligne droite imaginaire L10 en tant que point N, la distance entre le point A et le point N en tant que X, la distance entre le point N et le point J en tant que Y, une ligne perpendiculaire imaginaire perpendiculaire à une surface externe de pneu en tant que L11, et un point d'intersection entre la ligne perpendiculaire imaginaire L11 et la surface externe de pneu en tant que point K, la distance U entre le point J et le point K est de 2 à 10 mm. Le rapport Y/X entre la distance Y et la distance X est de 0,03 à 0,25.
