摘要： On a tread of tire, an inclined width direction groove, a plurality of zigzag sipes, an inclined width direction groove and a plurality of zigzag sipes are repeatedly formed in the tire circumferential direction. The inclined width direction groove communicates with the circumferential direction groove, one end of the sipe portion communicates with the narrow groove portion, and the other end of the sipe portion terminates in the rib-like block without communicating with the circumferential direction groove. The inclined width direction groove communicates with the circumferential direction groove, one end of the sipe portion communicates with the narrow groove portion, and the other end of the sipe portion terminates in the rib-like block without communicating with the circumferential direction groove.

摘要： A method of repairing a tire is a method to repair a damaged part of the tire, the damaged part being a part in a rubber layer of a tire side section located between a carcass ply and a tire surface and terminated within the rubber layer. The method of repairing the tire includes: a first step of opening the damaged part while in a state the tire is retained; a second step of injecting or applying an adhesive to the damaged part; a third step of releasing a damaged-part-opened state and bonding mutually opposing wall surfaces of the damaged part.

摘要： An estimating device estimates a target physical amount by a learned model that is learned by using as learning data a plurality of at least three physical amounts, which are of vary in accordance with deformation at a member deforming linearly or non-linearly. The learned model is a model that has been subjected to learning so as to output the target physical amount from inputs two physical amounts of an object of estimation that correspond to at least two physical amounts other than the target physical amount.

摘要： A tire according to the present disclosure is a tire including, in a tread surface, a block-shaped land portion partitioned by a partitioning groove or by the partitioning groove and a tread edge. The block-shaped land portion includes a first sipe and a second sipe extending from different positions in a surface of the block-shaped land portion inwardly in a tire radial direction. The first sipe includes, on a side of a sipe bottom, a widened portion with a larger sipe width than a side of the tread surface. The second sipe includes a plurality of holes recessed inwardly in the tire radial direction in a sipe bottom at positions separate in a sipe longitudinal direction.
