Abstract
【解決手段】トレッド部にタイヤ周方向に沿って延びる縦溝11を備えた空気入りタイヤにおいて、縦溝11の溝側壁14の開口側端部に設けられ縦溝11の内方へ行くほど縦溝11の底部16へ傾斜するテーパ面15と、テーパ面15から突出し異なる方向に延びる一対の突条22a,22bが屈曲部で接続されてなる突起20とを備えることを特徴とする。
【選択図】図3
Description
本実施形態に係る空気入りタイヤは、図示を省略したが、左右一対のビード部及びサイドウォール部と、左右のサイドウォール部の径方向外側端部同士を連結するように両サイドウォール部間に設けられたトレッド部10とを備えて構成されている。この空気入りタイヤは一対のビード部間にまたがって延びるカーカスを備える。
次に、第2実施形態について図5及び図6を参照して説明する。
表1において、気柱管共鳴音は、新品タイヤをJASO C606に準拠した室内音響ドラム試験機にて気柱管共鳴音(1000Hz)のノイズレベルを計測した値であり、比較例1との気柱管共鳴音レベルの差を示し、数値が小さいほど気柱管共鳴による騒音が低いことを示す。
雪上路面において、停止状態から20m地点到達までの最短時間の逆数であって、比較例1の結果を100として指数評価し、指数が大きいほどスノートラクション性能に優れていることを示す。
