摘要： A tire comprises a tread portion having outboard and inboard tread edges and provided with three main grooves to axially divide the tread portion into four land regions including a widest outboard middle land region, wherein first inclined grooves (16) extend across the entire width of the outboard middle land region; second inclined grooves (17) extend from a crown main groove and are terminated within the outboard middle land region; fourth inclined grooves (19) are connected to the second inclined grooves (17) and to the first inclined grooves on an outboard shoulder main groove side; and an angle of the first inclined groove (16) and an angle of the second inclined groove (17) with respect to the tire circumferential direction are gradually increases from the crown main groove toward the outboard tread edge.

摘要： 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.
