摘要： Provided herein are organic solvent-based processes for the removal of rubber from non-Hevea plants such as guayule shrubs. By the use of the processes, solid purified rubber can be obtained that contains 0.05-0.5 weight % dirt, 0.2-1.5 weight % ash, and 0.1-4 weight % resin (when it has been dried so as to contain 0.8 weight % volatile matter).

摘要： Provided is a technology for inhibiting the occurrence of uneven wear at shoulder-side edges of blocks in a motorcycle tire having a block pattern. A motorcycle tire (100) includes plural blocks (11) and (12) that are arranged on a tread ground-contact surface. In a tire widthwise cross-section of a tread portion (1), when regions obtained by bisecting a tread half-width region measured along the tire surface from a tire equator CL to a tread ground-contact end TE are each defined as a tread center portion Tc and a tread shoulder portion Ts, a middle block (12) among the plural blocks, whose outer wall surface (12A) on the tire width-direction outer side is positioned in the tread shoulder portion Ts, is configured such that an upper end portion is chamfered only for the outer wall surface (12A) and a chamfered part (12B) is thereby formed on the middle block (12).

摘要： A pneumatic tire includes, on a tread surface, circumferential main grooves extending in a tread circumferential direction, and land portions defined between circumferential main grooves adjacent in a tread width direction among the circumferential main grooves, or by a circumferential main groove and a tread edge. The land portions include widthwise grooves (and/or widthwise sipes), extending in the tread width direction, each including a gradually decreasing groove (sipe) width portion in which a groove (sipe) width gradually decreases from the tread surface towards an inner side in the tire radial direction, a constant groove (sipe) width portion that extends from the gradually decreasing groove (sipe) width portion towards the inner side in the tire radial direction and has a constant groove (sipe) width, and a branched groove (sipe) portion branching and extending from the constant groove (sipe) width portion towards the inner side in the tire radial direction.

摘要： A pneumatic tire of the present disclosure includes, on a tread surface, a plurality of circumferential main grooves extending in the tire circumferential direction, and a plurality of land portions defined between circumferential main grooves adjacent in the tire width direction among the plurality of circumferential main grooves or by the circumferential main grooves and tread edges. The land portions include at least one circumferential sipe extending in the tire circumferential direction. The circumferential sipe includes a plurality of widened portions arranged in the tire circumferential direction. In a reference state, each widened portion is formed only from a portion that, from one side towards the other side in the tire circumferential direction, extends from the tread surface inward in the tire radial direction.

摘要： A tire state monitoring system comprises an acquisition device and a control device. The acquisition device is configured to repeatedly acquire a pressure and temperature inside a tire. The control device is configured to: calculate, based on ratios between the pressure and temperature acquired in a first period, a representative value of the ratios in the first period; and compare a ratio between the pressure and temperature acquired in a second period after the first period with the representative value, to determine whether the pressure inside the tire has dropped.

摘要： The present disclosure aims at providing an EPDM-containing rubber composition capable of exhibiting excellent adhesion to a metal member without necessitating inclusion of a cobalt salt of organic acid therein. Specifically, a rubber composition includes therein: a rubber component containing ≥20 phr of EPDM; a rubber-metal adhesion promoter; a vulcanization accelerator other than a thiuram-based compound; and no thiuram-based vulcanization accelerator, wherein the rubber-metal adhesion promoter contains a specifically formulated metal salt of aliphatic carboxylic acid.

摘要： Disclosed herein are methods for improving the rolling resistance of a tire rubber composition by providing a rubber composition including a rubber component which includes a majority by weight of guayule rubber where the guayule rubber includes a bagasse component, and a filler component where the filler component is free of silica, and including at least one silane in the rubber composition, where the at least one silane is selected from the group consisting of mercaptosilanes, blocked mercaptosilanes, and alkoxysilanes. Also disclosed is a tire rubber composition which comprises (a) 100 parts of a rubber component including a majority by weight of guayule rubber where the guayule rubber includes a bagasse component, (b) a filler component, where the filler component is free of silica, and (c) at least one silane selected from the group consisting of mercaptosilanes, blocked mercaptosilanes, and alkoxysilanes.
