Abstract: A pneumatic tire has a plurality of long radially extending ridges disposed at intervals in the tire circumferential direction on at least one side section of the tire, the ridges being non-uniformly disposed around the tire circumferential direction. The ridges are disposed, for example, so that the angles ? between the ridges vary in the tire circumferential direction.

Abstract: The pneumatic tire having a vehicle inner/outer orientation when mounted on a vehicle includes: protrusions provided on a vehicle inner side on a tire side portion in a tire circumferential direction; and a plurality of recesses provided on a vehicle outer side on a tire side portion, wherein the height of projection of the protrusions from the tire side portion is more than 4 mm and not more than 10 mm, the protrusions are formed elongated and the bending rigidity in a lateral direction satisfies a range not less than 0.1 MPa·mm4 and not more than 10,000 MPa·mm4.

Abstract: A data analysis method targeting, in a plurality of input values and a plurality of output values having a predetermined relationship, two types of data, namely input data representing the plurality of input values and output data representing the plurality of output values. The method includes a step of finding at least one of a first indicator and a second indicator in objective function space, the plurality of output values being defined as an objective function. The first indicator is a distance from a preset value of the values of at least two objective functions among the values of the plurality of objective functions. The second indicator is expressed as a ratio of the values of at least two objective functions among the values of the plurality of objective functions.

Abstract: A protrusion that projects from the inner wall surface of a tire house towards the rotational axis side is provided on the tire house side in a range from an edge of a tire cross-sectional width S that corresponds to a vehicle inner side of the pneumatic tire to a vehicle outer side. A plurality of ridges and/or recesses is provided on at least one tire side section on the pneumatic tire side. Where a maximum distance of the ridges from the surface of the tire side section is designated as Hp, a maximum distance of the recesses from the surface of the tire side section is designated as Hd, and the tire cross-sectional width of the pneumatic tire is designated as S, ranges 0.005?Hp/S?0.05 and/or 0.001?Hd/S?0.01 are satisfied.

Abstract: In a tire, protrusions are disposed at intervals in the tire circumferential direction in at least one tire side portion, extending in an elongated manner from the inner side to the outer side in the tire radial direction including the maximum tire width position, the extension direction of each of the protrusions is inclined with respect to the tire radial direction, and the each of the protrusions adjacent to each other in the tire circumferential direction is disposed with the opposite orientation of the inclination with respect to the tire radial direction.

Abstract: A pneumatic tire includes a turbulent flow generating fin on a surface of a tire side portion. A plurality of the fins is arranged in a tire radial direction having a predetermined gap so as to form a fin row. Additionally, a plurality of the fin rows is disposed in a tire circumferential direction at a predetermined pitch. Moreover, the adjacent fins are disposed so as to overlap each other in the tire circumferential direction and a tire radial direction.
