摘要： A heavy load pneumatic tire (100) includes a carcass ply (40) that forms a framework of the tire, and a belt layer (15) located outside the carcass ply in a tire radial direction in a tread section (10). The carcass ply (40) includes a first curvature change portion (P1) that is a boundary between a first segment (P0-P1) containing a tire equator line (CL) and a second segment (P1-P2) that is located outside the first segment in a tire width direction and inside the first segment in the tire radial direction and whose curvature is larger than a curvature of the first segment in a cross-section, and a second curvature change portion (P2) that is a boundary between the second segment and a third segment (P2-P3) that is located inside the second segment in the tire radial direction and whose curvature is smaller than the curvature of the second segment on the cross section. The tire further includes a cushion rubber (17a) whose inner edge is located at the first curvature change portion (P1) and that is disposed between the carcass ply (40) and the belt layer (15).

摘要： A tire evaluation method is a tire evaluation method for evaluating a tire mounted on a vehicle traveling by autonomous driving on a course with a defined reference path and includes a step (S 1) of acquiring data on a travel path of the vehicle and data on a target path set during travel so that the vehicle passes through the reference path, a step (S4) of extracting a specific region from the data on the target path, a step (S7) of calculating a positional deviation between the specific region and the travel path of the vehicle, and a step (S8) of evaluating a control followability of the tire with respect to the vehicle based on the positional deviation.

摘要： The fluid pressure actuator comprises an actuator body portion 100 and a sealing mechanism 200 that seals the end of the actuator body portion 100 in the axial direction D AX of the actuator body portion 100. The sealing mechanism 200 includes a sealing member 210 into which the actuator body portion 100 is inserted, a caulking ring 230 provided on the outer peripheral surface of the actuator body portion 100 inserted into the sealing member 210 and restricting the actuator body portion 100, and a locking ring 220 that locks the sleeve to the sealing member 210. The sealing member 210 includes a body portion 212 into which the tube 110 is inserted, and the outer diameter of the body portion 212 is larger than the inner diameter of the tube 110 in the portion not inserted into the body portion 212.

摘要： Provided is a rubber composition for a tire with which it is possible to obtain a tire having excellent wet gripping on both dense graded asphalt paving and porous asphalt paving and having high road surface robustness. The tire rubber composition contains a rubber component including an isoprene-based rubber (A) having a glass-transition temperature of -50°C or lower, a reinforcing filler (B), and a resin component (C). The proportion constituted by the isoprene-based rubber (A) in 100 parts by mass of rubber component is not less than 15 and less than 50 parts by mass. The resin component (C) is at least partially hydrogenated and has an SP value difference with the isoprene-based rubber (A) of 1.40 (cal/cm 3 ) 1/2 or less. A composition parameter P1 calculated by a specific formula (I-1) is 1,000 or more, and a composition parameter P2 calculated by a specific formula (I-2) is 0.25 or more.
