Abstract
Official abstract text for this publication.
A tread section is formed with plural circumferential direction main grooves extending around a tire circumferential direction, and is formed with a first rib and a second rib between the plural circumferential direction main grooves. The first rib and the second rib are formed with first arc shaped faces that have arc shapes about centers within the ribs. The first rib and the second rib are also formed with second arc shaped faces that are respectively formed continuously to the first arc shaped faces and that are have smaller radius of curvature than the first arc shaped faces.
First claim
Opening claim text (preview).
1 . A pneumatic tire, comprising: a plurality of circumferential direction main grooves that are formed at a tread section and that extend around a tire circumferential direction; a land portion that is formed between the plurality of circumferential direction main grooves; first arc shaped faces that are formed at both tire width direction edges of the land portion, and that have an arc shape about a center within the land portion as viewed in a tire radial direction cross-section; and an outer second arc shaped face that is formed at an edge on a fitted tire outer side of the land portion, that is formed continuously from the first arc shaped face toward a tire width direction outer side of the land portion and toward a groove bottom, and that has an arc shape, about a center within the land portion as viewed in the tire radial direction cross-section, having a smaller radius of curvature than the first arc shaped face. 2 . The pneumatic tire of claim 1 , wherein: an inner second arc shaped face is formed at a fitted tire inner side of the land portion so as to be continuous from the first arc shaped face toward the tire width direction outer side of the land portion and toward a groove bottom, and having an arc shape about a center within the land portion as viewed in the tire radial direction cross-section; and, as viewed in the tire radial direction cross-section, a radius of curvature of the inner second arc shaped face is smaller than the radius of curvature of the first arc shaped face and is the radius of curvature of the outer second arc shaped face or smaller. 3 . The pneumatic tire of claim 2 , wherein a tire radial direction drop-off amount from a tread face of the land portion to a lower end of the outer second arc shaped face is a tire radial direction drop-off amount from the tread face of the land portion to a lower end of the inner second arc shaped face or greater.
