摘要： A rubber composition according to an embodiment contains a diene rubber and silica. A change rate of a distance between aggregates represented by V50/V0 calculated by an inertia radius V50 of a silica aggregate and an inertia radius V0 of the silica aggregate is 1.30 or more. The inertia radius V50 is obtained by performing a small-angle X-ray scattering measurement in a state where a vulcanized rubber obtained by vulcanizing the rubber composition is elongated by 50%, and the inertia radius V0 is obtained by performing a small-angle X-ray scattering measurement in a state where the vulcanized rubber is not elongated.

摘要： A pneumatic tire includes block rows which are arranged in a tire width direction and each of which includes a plurality of blocks defined by main grooves extending in a tire circumferential direction and lateral grooves extending in a tire width direction. The plurality of block rows includes inner block rows which are the block rows other than an outermost block row located most outwardly in the tire width direction. Numbers of the blocks included in the inner block rows increase toward an inner side in the tire width direction. The blocks in each of the inner block rows include an auxiliary-grooves-formed block having, on an outer surface thereof, an auxiliary groove region in which a plurality of drain auxiliary grooves extending in the tire circumferential direction are formed. Occupied areas in each of the inner block rows decrease toward the inner side in the tire width direction.

摘要： A tire groove depth display method includes a grounded part extracting step, a groove depth calculating step, an image generating step, and a displaying step. The grounded part extracting step extracts a grounded part on a surface of a tread part of a tire as a plurality of areas sandwiching a tire groove. The groove depth calculating step calculates a depth of the tire groove between respective areas of the grounded part. The image generating step generates an image that shows the areas extracted by the grounded part extracting step and information on the depth of the tire groove calculated by the groove depth calculating step. The displaying step displays the image generated by the image generating step.

摘要： A method for producing a rubber wet masterbatch, the method including: adding a rubber latex solution to a carbon black-containing slurry aqueous solution in which a carbon black is dispersed in water and mixing the solutions to produce a carbon black-containing rubber latex aqueous solution; coagulating the carbon black-containing rubber latex aqueous solution obtained to produce a carbon black-containing rubber coagulum; cleaning the carbon black-containing rubber coagulum obtained to produce a cleaned carbon black-containing rubber coagulum; and dehydrating and drying the cleaned carbon black-containing rubber coagulum obtained to produce a rubber wet masterbatch, wherein an amount of an acetone extract from the cleaned carbon black-containing rubber coagulum is 2% by mass or less after drying the coagulum at 23° C. for 24 hours and further at 90° C. for 2 hours. Vulcanized rubber having excellent low exothermicity and excellent abrasion resistance can be obtained by the method.
