Description
(1)トレッド面に、複数の主溝で区画されたリブ状および/またはタイヤ幅方向に延びるラグ溝によって区画された複数のブロック状の陸部を有する空気入りタイヤにおいて、該陸部にサイプまたは小孔が設けられるとともに、該サイプまたは小孔の深さよりも小さな高さを有する多数の突起が配置され、かつ該多数の突起は、該突起どおしの間に網目状に形成された流路が少なくとも3方向から集まる流路集合箇所にて該流路幅が広くなる形状を呈して配されてなり、かつ、該突起部面積/ブロック陸部面積の比率を0.5以上0.9以下とした空気入りタイヤ。
(2)前記突起の高さが、0.1〜0.5mmである上記(1)記載の空気入りタイヤ。
(3)前記突起の最短隣接距離が、0.2〜1.0mmである上記(1)または(2)記載の空気入りタイヤ。
(4)前記突起の踏面面積が0.03〜20mm2 である上記(1)〜(3)のいずれかに記載の空気入りタイヤ。
(5)前記突起の踏面の形状が略円形である上記(1)〜(4)のいずれかに記載の空気入りタイヤ。
氷上テストコースにおいて、初速80km/hから完全停止までの制動距離を計測した。従来例のタイヤでの制動距離を100として指数評価で表した。指数が大きいほど雪上制動が良好なものである。
雪上テストコースにおいて、テストドライバーによる官能評価を行い、従来例のタイヤでの評価を100とした指数評価で表した。指数が大きいほど雪上操縦安定性が良好なものである。
