Pneumatic radial tires

摘要

In a pneumatic radial tire having a belt of at least two belt layers, in which the belt (24) comprises a maximum-width belt layer (25) containing cords (28) slantly arranged with respect to an equatorial plane (S) of the tire and a narrow-width belt layer (26) arranged at the outside of the maximum-width belt layer in a radial direction and containing cords (29) arranged in an oppositely inclined direction to the cords of the maximum-width belt layer, the belt end separation is controlled by arranging a reinforcing layer (35) containing cords (36) arranged in an oppositely inclined direction to the cords (28) of the maximum-width belt layer (25) so as to overlap with an outer end portion (25a) of the maximum-width belt layer (25) located outward from an outer end (26a) of the narrow-width belt layer (26) in the widthwise direction thereof.
