Abstract
A tire includes a pattern portion on a surface of a sidewall portion. The pattern portion includes an outer pattern and an inner pattern. The outer pattern includes a plurality of outer ridges disposed concentrically around a first point on a tire circumferential line on an outer side in a tire radial direction and extending toward a second point, on the tire circumferential line, which is different from the first point. The inner pattern includes a plurality of inner ridges disposed concentrically around the second point on an inner side in the tire radial direction and extending toward the first point. Each of the outer ridges connects with one of the inner ridges on the tire circumferential line.

A tire comprising a sidewall portion, wherein the sidewall portion has a pattern portion on a surface, wherein the pattern portion comprises an outer pattern formed outwardly of a tire circumferential line passing through the pattern portion, and an inner pattern formed inwardly of the tire circumferential line, wherein the outer pattern comprises a plurality of outer ridges disposed concentrically around a first point on the tire circumferential line on an outer side in a tire radial direction and extending toward a second point, on the tire circumferential line, which is different from the first point, wherein the inner pattern comprises a plurality of inner ridges disposed concentrically around the second point on an inner side in the tire radial direction and extending toward the first point, wherein each of the outer ridges connects with one of the inner ridges on the tire circumferential line, and wherein the outer ridges adjacent to each other in a tire circumferential direction are disposed at regular pitches having a uniform spacing between adjacent outer ridges along an entire length of the outer ridges, and the inner ridges adjacent to each other in the tire circumferential direction are disposed at regular pitches having a uniform spacing between adjacent inner ridges along an entire length of the inner ridges.
A tire comprising a sidewall portion, wherein the sidewall portion has a plurality of pattern portions on a surface and aligned in a tire circumferential direction, wherein each pattern portion comprises an outer pattern formed outwardly of a tire circumferential line passing through the pattern portion, and an inner pattern formed inwardly of the tire circumferential line, wherein the outer pattern comprises a plurality of outer ridges disposed concentrically around a first point on the tire circumferential line on an outer side in a tire radial direction and extending toward a second point, on the tire circumferential line, which is different from the first point, wherein the inner pattern comprises a plurality of inner ridges disposed concentrically around the second point on an inner side in the tire radial direction and extending toward the first point, and wherein each of the outer ridges connects with one of the inner ridges on the tire circumferential line, wherein the outer ridges have analogous shapes and the inner ridges have analogous shapes, wherein each of the outer ridges and each of the inner ridges extend so as to be arc-shaped with each of the outer ridges and each of the inner ridges having a respective single radius of curvature, wherein the tire circumferential line passes through positions distant from an intermediate position of the pattern portion in the tire radial direction by 10% or less of a tire-radial length of the pattern portion in a tire radially inward or outward direction, wherein the outer ridges adjacent to each other in a tire circumferential direction are disposed at regular pitches having a uniform spacing between adjacent outer ridges along an entire length of the outer ridges and the inner ridges adjacent to each other in the tire circumferential direction are disposed at regular pitches having a uniform spacing between adjacent inner ridges along an entire length of the inner ridges.
A tire comprising a sidewall portion,
- wherein the sidewall portion has a pattern portion on a surface,
- wherein the pattern portion comprises an outer pattern formed outwardly of a tire circumferential line passing through the pattern portion, and an inner pattern formed inwardly of the tire circumferential line,
- wherein the outer pattern consists of a plurality of outer ridges disposed concentrically around a first point on the tire circumferential line on an outer side in a tire radial direction and extending toward a second point, on the tire circumferential line, which is different from the first point,
- wherein the inner pattern consists of a plurality of inner ridges disposed concentrically around the second point on an inner side in the tire radial direction and extending toward the first point, and
- wherein each of the outer ridges connects with one of the inner ridges on the tire circumferential line.
A tire comprising a sidewall portion,
- wherein the sidewall portion has a plurality of pattern portions on a surface and aligned in a tire circumferential direction,
- wherein each pattern portion comprises an outer pattern formed outwardly of a tire circumferential line passing through the pattern portion, and an inner pattern formed inwardly of the tire circumferential line,
- wherein the outer pattern comprises a plurality of outer ridges disposed concentrically around a first point on the tire circumferential line on an outer side in a tire radial direction and extending toward a second point, on the tire circumferential line, which is different from the first point,
- wherein the inner pattern comprises a plurality of inner ridges disposed concentrically around the second point on an inner side in the tire radial direction and extending toward the first point, and
- wherein a first end of each of the outer ridges of a respective pattern potion connects with a first end of one of the inner ridges of the respective pattern potion on the tire circumferential line so as to have an inflection point on the tire circumferential line, a second end of each of the outer ridges terminates near a first adjacent pattern portion arranged adjacent to the respective pattern portion in a first tire circumferential direction, and a second end of each of the inner ridges terminates near a second adjacent pattern portion arranged adjacent to the respective pattern portion in a second tire circumferential direction.
