Abstract: A tire management system includes a management apparatus and a database portion. The tire management system acquires travel history data concerning a history of causes of degradation of tire performance of a tire mounted on a vehicle, and decides a replenishing agent for restoring the tire performance that has been degraded, based on the acquired travel history data.

Abstract: Provided is a pneumatic tire that can suppress an increase in weight and deterioration of rolling resistance even when a protrusion-like mark having a large raised height is provided on a sidewall portion. A green tire production method 100 includes: a first step S1 of forming a cylindrical or annular unvulcanized carcass; a second step S2 of winding an unvulcanized sidewall rubber on each of a pair of outer circumferential surfaces of the carcass on an outer side in an axial direction; and a third step S3 of locally attaching an unvulcanized band-shaped rubber to a part of an outer circumferential surface of at least one of the sidewall rubbers.

Abstract: A putter-type golf club head that, when oriented in a reference position, includes a blade portion having a striking face, a top line, and a sole, the striking face in turn including a face center. The club head further includes a rear portion in communication with, and rearward of, the blade portion, and it includes an alignment element rearward of, and recessed toward the sole from, the top line. The alignment element defines a virtual center line segment oriented in a substantially front-to-rear direction at a height between 19 mm and 24 mm from a lowermost point of the sole, the center line segment having a length no less than 34 mm and being not spaced more than 10 mm from a virtual vertical plane passing through the face center and extending generally perpendicular to the striking face. A width of the club head is no less than 3.0 in.

Abstract: A motorcycle tire includes a tread portion, a pair of sidewall portions, a pair of bead portions, and a carcass extending between the bead portions in a toroidal manner. Each of the sidewall portions is provided with a sidewall rubber. In each of the sidewall portions, a minimum thickness (Ts) is 50% or less of a minimum tire thickness (Ta) from a respective one of tread edges to a tire inner cavity surface. A minimum thickness (Ds) of the sidewall rubber is from 0.3 to 1.9 mm.

Abstract: A motorcycle tire comprises a tread portion provided with a belt layer and a radially outer band layer. The belt layer comprises a first belt ply on a carcass 6 and a second belt ply thereon. The band layer is made of a spirally wound band cord and has a developed width smaller than that of the belt layer. In a meridian cross-section of the tire mounted on a standard wheel rim at an internal pressure of 10 kPa: the radius of curvature Rc of the ground contacting surface of the tire in its crown region is less than 95% of the cross-sectional width of the tire; and the radius of curvature Rc is smaller than a radius of curvature Rb of the ground contacting surface in shoulder regions.

Abstract: A pneumatic tire (1) includes: a tread portion (2) including a land portion (24) divided by a plurality of main grooves (22) formed on a tread surface (21); an inner liner (7) constituting a tire inner surface (7A) on an inner side of the tread portion (2); and a mount member (10) which is provided on the tire inner surface (7A), and to which electric equipment can be attached. In the pneumatic tire (1), acetone extraction amount (AE2) of a rubber composition constituting the inner liner (7) is larger than acetone extraction amount AE1 of a rubber composition constituting the mount member (10).

Abstract: A motorcycle tire set includes a front-wheel tire and a rear-wheel tire. Each of the front and rear-wheel tires includes a carcass, a band layer arranged radially outwardly of the carcass in the tread portion, and a tread rubber arranged radially outwardly of the band layer. The carcass includes a carcass ply including carcass cords. The band layer includes a jointless band ply in which a band cord is circumferentially wound spirally at an angle equal to or less than 5 degrees. The tread rubber includes a crown rubber portion. An angle θ1 of the carcass cords of the front-wheel tire is 65 degrees or more with respect to the tire circumferential direction. A rubber hardness of the crown rubber portion of the rear-wheel tire is greater than a rubber hardness of the crown rubber portion of the front-wheel tire.

Abstract: A pneumatic tire can include a tread portion, a pair of sidewall portions, bead portions, and a carcass. At least one sidewall portion can include a first sidewall rubber arranged outside the carcass in a tire axial direction. The first sidewall rubber can include a different color rubber layer and a barrier rubber layer. The different color rubber layer can have a color different from a basic color of an outer surface of the at least one sidewall portion. At least a part of the different color rubber layer can be exposed in the outer surface of the at least one sidewall portion. The barrier rubber layer can be arranged between the different color rubber layer and the carcass. The barrier rubber layer can include a first portion having a rubber compounding to suppress migration of rubber compounding agents on the carcass side to the different color rubber layer.
