A pneumatic tire includes a serration region in a predetermined region of a sidewall portion. The serration region is formed by arranging a plurality of ridges, the plurality of ridges protruding from a base surface in parallel to each other and being periodically arranged. A length of one cycle of the plurality of ridges along the base surface is 0.5 mm or more and 0.7 mm or less. The pneumatic tire includes a plane portion surrounded by the serration region.

The present invention is directed to a tire comprising a tread, two sidewalls, a carcass and at least two belts arranged radially between the carcass and the tread in a crown area of the tire. The tread has at least one axially outer edge portion covering the axially outermost edge of at least one of the belts and comprising a different rubber composition than a portion of the tread neighboring the axially outer edge portion of the tread. Furthermore, one of the sidewalls at least partially covers and contacts the axially outer surface of the axially outer edge portion of the tread.

Provided is a tire having excellent rolling resistance and improved pass-by noise performance. The tire is a pneumatic tire comprising a side rubber provided on an outer side of a carcass in a tire width direction, in a sidewall portion, wherein a thickness of the side rubber in the tire width direction at a tire maximum width position is 1 mm or more, and a ratio 0° C. tan δ/30° C. tan δ of 0° C. tan δ to 30° C. tan δ of the side rubber is 2.00 or more, where the 0° C. tan δ is tan δ at 10 Hz and 0° C., and the 30° C. tan δ is tan δ at 10 Hz and 30° C.

A tire sidewall comprising a vulcanized rubber and a high molecular weight wax.

A tire includes a tread, a crown reinforcement, a carcass reinforcement with at least one ply wound about a pair of bead cores and through two sidewalls of the tire, and a cut/puncture resistant sidewall layer disposed adjacent a part of the carcass reinforcement within one of the sidewalls, the cut/puncture sidewall layer being formed of a plurality of cords, each cord including one nylon cord having S 4-8 tpi (twists per inch), one aramid cord having Z 4-8 tpi, and the nylon cord and the aramid cord being twisted together with S 3-7 tpi.

The present invention provides a tire including a side portion (104), a black rubber layer (113), a stain-preventing rubber layer (112) disposed adjacent to the black rubber layer, and a colored layer (111) disposed on the surface of the stain-preventing rubber layer and exposed on the outer surface of the side portion; a tire including a colored layer (207) disposed on the outer surface of the tire, and an underlayer rubber (208) disposed on the tire-interior side of the colored layer, wherein the colored layer is formed by curing a UV-curable paint; and a tire including a colored layer (302) on the surface of the side portion (301) of the tire, wherein the colored layer includes a marking (303).

Provided is a tire capable of maintaining excellent appearance over a long time. A tire comprises a polyurethane foam layer laminated on an outer layer of the tire, wherein, in the polyurethane foam layer, a binder layer is provided on a surface of a polyurethane foam.

A pneumatic tire is configured by a resin tire frame member. An inner face of the tire frame member is provided with an attachment section. The attachment section is configured so as to attach a sound-absorbing material inside the tire frame member. The sound-absorbing material employs, for example, a spongey material, and the sound-absorbing material is capable of absorbing sound.

To improve durability performance and rolling resistance performance in a well-balanced manner. It is a tire for heavy loads including a carcass ply (6A). A sidewall rubber (3G) includes an inside rubber part (15) on the carcass (6) side, and an outside rubber part (16) disposed on the outside thereof and forming a tire outer surface. The inside rubber part (15) has a loss tangent tan δ1 less than the outside rubber part (16), and their difference is 0.010 to 0.035. The inside rubber part (15) has a complex elastic modulus less than the outside rubber part (16), their difference is 0.5 to 1.4 (MPa). The outer end (15s) in the tire radial direction of the inside rubber part (15) contacts with the outer surface (2h) in the tire axial direction of the tread rubber (2G), and the inner end (15u) in the tire radial direction is disposed radially inside the outer end (6e) in the tire radial direction of the turned up portion (6b) of the carcass ply (6A).

A low compaction cantilevered tire construction is provided which is designed for use at relatively low inflation pressures and which has sidewalls with a relatively uniform bending resistance through the majority of the sidewall. When the tire is placed under high loads at low inflation pressures the sidewall deflects substantially radially and allows the tread portion of the tire to maintain its intended shape thus improving the contact area of the tire and providing a tire having a relatively high contact area and thus relatively low soil compaction for a given loading.
