Description

すなわち、本発明のタイヤは、サイドウォール部に、凸条から形成される装飾帯と、該装飾帯のタイヤ径方向内側および外側にそれぞれ隣接して配置された内側外縁凸部および外側外縁凸部と、を備え、
前記装飾帯が、前記内側外縁凸部から前記外側外縁凸部まで途切れずに連続して延びる前記凸条によって形成される装飾要素を、タイヤ周方向に複数配設してなり、
タイヤ周方向に隣接する前記装飾要素同士が、前記凸条同士の間に形成されてタイヤ径方向に延びる谷部によって分断されており、
前記装飾要素のうちの少なくとも一部が、前記凸条を、部分的にジグザグ状に密に配列させた第１領域と、疎に配列させた第２領域と、を備え、該第１領域と、該第２領域とが、タイヤ外表面側から見たときに、同じ輪郭形状を有し、かつ、該装飾要素が、異なる３方向以上から前記凸条の交差する交差部を備えないことを特徴とするものである。 That is, the tire according to the present invention includes a decorative band formed of protrusions on the sidewall portion, and an inner outer edge convex portion and an outer outer edge convex portion disposed adjacent to the inner side and the outer side in the tire radial direction of the decorative band, respectively. And comprising
The decorative band is provided with a plurality of decorative elements formed in the tire circumferential direction, which are formed by the ridges extending continuously without interruption from the inner outer edge convex part to the outer outer edge convex part,
The decorative elements adjacent to each other in the tire circumferential direction are separated by a valley formed between the ridges and extending in the tire radial direction,
At least a part of the decorative element includes a first region in which the ridges are partially densely arranged in a zigzag shape, and a second region in which the convex stripes are sparsely arranged, and the first region; The second region has the same contour shape when viewed from the tire outer surface side, and the decorative element does not have an intersection where the ridges intersect from three or more different directions. It is a feature.

本発明のタイヤにおいては、前記第１領域が、前記装飾帯全体のうちに、前記凸条の延在方向の異なるものを含むことが好ましく、より好ましくは、前記第１領域における前記凸条の延在方向が、タイヤ径方向またはタイヤ周方向に隣接する該第１領域間で異なるものとする。 In the tire according to the present invention, it is preferable that the first region includes ones having different extending directions of the ridges in the entire decoration band, and more preferably, the ridges in the first region. The extending direction is different between the first regions adjacent to each other in the tire radial direction or the tire circumferential direction.
