Description
タイヤ幅方向WDに対する角度の最大値(図1では、第1ショルダ主溝12Aとの連結部分における角度)が10度以下であることが好ましい。
上記実施形態では、図5及び図6に示すように、溝壁40に対するテーパ面42の角度θ2を一定に保ったままで、タイヤ幅方向一方側WD1から他方側WD2に向かって第2接地端E2に近づくほど、テーパ面42と溝壁40との境界部分43が溝底41に近づき、かつ、テーパ面42と接地面との境界部分44がショルダ横溝38の外側へ広がるように設けることで、タイヤ幅方向他方側WD2に行くほどテーパ面42を徐々に幅広とする場合について説明したが、これ以外にも図7に示すショルダ横溝138や図8に示すショルダ横溝238のように構成してもよい。
水深8mmのウェット路面上で各タイヤを正転及び反転方向にそれぞれ回転させ、ハイドロプレーニング現象が発生したときの速度を、正転回転時及び逆転回転時のそれぞれの場合で測定し、正転回転時と逆転回転時の速度差の逆数を指数化して評価した。比較例1の結果を100とし、指数が大きいほど正転回転時及び逆転回転時における排水性能差が小さいことを示す。
正規リムに組み付け正規内圧を充填した各テストタイヤを試験車両(ワゴン車)に装着し、乾燥した路面で直進走行やコーナリング走行を実施した。評価は、ドライバーの官能試験により評価し、比較例1を100とした指数で表示した。指数が大きいほど操縦安定性が良好であることを示す。
