Abstract
【解決手段】タイヤ周方向に沿って延びる主溝1に面したブロック3の側壁4が、一対の角部41,42の間でタイヤ周方向に対して傾斜して延び、その一対の角部41のうち、主溝1の幅方向内側に位置する方を内側角部とし、主溝1の幅方向外側に位置する方を外側角部とするとき、内側角部41では、側壁4が溝底10に向かって主溝1の幅方向外側に拡がる階段状面により形成され、内側角部41から外側角部42に向かって、その階段状面における幅方向外側への拡がりを小さくする。

Description
車両(6600cc、4WDディーゼルトラック)にタイヤを装着して空気圧を420kPaとし、レイングルーブ模擬路を走行してフィーリング評価を実施した。比較例1の結果を100として指数で評価し、数値が大きいほどグルーブワンダーを抑制できていることを示す。
上記の車両にタイヤを装着して空気圧を420kPaとし、水深8mmでハイドロプレーニング現象を起こす速度を計測した。比較例1の結果を100として指数で評価し、数値が大きいほど速度が大きく、ハイドロプレーニング性能に優れていることを示す。
上記の車両にタイヤを装着して空気圧を420kPaとし、一般路を12000km走行した後に、ブロックの角部での(横溝間での)摩耗段差量を測定した。数値が小さいほど、ヒールアンドトウ摩耗を抑制できていることを示す。
