Abstract: 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.

Abstract: A pneumatic tire with short fibers fixed to the inner surface of the tire with improved peel resistance, and a method of producing such a pneumatic tire. The pneumatic tire has a carcass toroidally extending from a tread portion along a pair of sidewall portions to a pair of bead portions, and bead fillers provided radially outwardly of bead cores embedded in the bead portions, including flocking areas in which many short fibers are fixed to at least part of an inner surface of the pneumatic tire with an adhesive. The flocking areas are positioned such that their tire radial direction inner ends are positioned inwardly in the tire radial direction as compared to the tire radial direction outer ends of the bead fillers and are spaced a given distance outward in the tire radial direction apart from bead toes.
