摘要： The present invention enhances noise performance and anti-uneven wear performance. A pneumatic tire 1 includes a belt layer 7 including at least one belt ply in which belt cords 15 are arranged at an angle of 10 to 40° with respect to a tire equator C. A tread pattern formed on a surface of the tread portion 2 includes a pitch line 22 in which at least two kinds of pattern-constituting units 21 having different pitches in a circumferential direction of the tire are arranged in the circumferential direction of the tire. The belt cords 15 are arranged relatively densely on an inner side of the pattern-constituting unit 21 having a small pitch, and relatively thinly on an inner side of the pattern-constituting unit 21 having a large pitch.

摘要： A tire 2 includes: a tread 4 forming a tread surface 20; a band 14 disposed inward of the tread 4 in a radial direction; and a belt 12 disposed between the tread 4 and the band 14 in the radial direction. The tread 4 includes a center region 22 disposed at a center in an axial direction, and a shoulder region 24 disposed on an outer side in the axial direction. The band 14 includes a band cord. The band cord is helically wound and extends in a circumferential direction. The belt 12 includes a belt cord. The belt cord extends so as to be tilted relative to an equator plane. An absolute value of an angle of the belt cord relative to the equator plane is not less than 70° and not greater than 90°.

摘要： A tire with radial carcass reinforcement comprises a crown reinforcement including a layer of circumferential reinforcing elements distributed axially at a variable pitch. The layer of circumferential reinforcing elements is radially crowned by a tread strip, which is connected to two beads by two sidewalls. The layer of circumferential reinforcing elements comprises five parts, including a central part, two intermediate parts and two axially outer parts. The value of the pitch in the two intermediate parts is less than a value of the pitch in the two axially outer parts. Each axially outer part is axially separated from the central part by a corresponding intermediate part. The value of the pitch in each intermediate part is less than a value of the pitch in the central part, and the value of the pitch in each axially outer part is less than the value of the pitch in the central part.

摘要： A pneumatic tire for a motorcycle includes a tread reinforcing cord layer and a tread rubber. The tread rubber includes a base rubber layer and a pair of shoulder rubber layers. The base rubber layer includes a cover portion covering at least the tread reinforcing cord layer over an entire width thereof and a convex portion protruding radially outwardly from the cover portion to form a crown ground contacting surface. The shoulder rubber layers are arranged radially outside the cover portion to form shoulder ground contacting surfaces. The base rubber layer is made of a first rubber composition having larger hardness than the shoulder rubber layers, and the shoulder rubber layers are made of a second rubber composition containing larger amount of oil component than the base rubber layer.

摘要： A pneumatic tire has a belt layer disposed between a carcass ply and a circumferential tread, defining a crown region. The belt layer includes a first section and a second section laterally spanning the crown region. The first section includes a plurality of first reinforcing members constructed of a plurality of first filaments composed of a first material. The second section includes a plurality of second reinforcing members constructed of a plurality of second filaments composed of a second material. The first section is characterized by a first fabric density and a first crown angle. The second section is characterized by a second fabric density and a second crown angle. At least one of the first crown angle, the first material, the first number of first filaments, and the first fabric density is different from the respective second crown angle, second material, second number of filaments, and second fabric density.
