Abstract
【解決手段】トレッド部1に溝2,3によって区画された複数の陸部4を備え、これら陸部4の接地面にそれぞれ複数本の細溝6を設けた空気入りタイヤにおいて、細溝6のタイヤ周方向に対する傾斜角度を陸部4のタイヤ幅方向の中央領域4aよりもその両側の端部領域4b,4cで相対的に大きくする。
【選択図】図2
Description
試験タイヤをリムサイズ15×6 1/2Jのホイールに組み付けて排気量2000ccの後輪駆動車に装着し、空気圧200kPaの条件で、氷上を速度40km/hの走行状態からABS制動で停止するまでの制動距離を測定した。評価結果は、測定値の逆数を用い、従来例1を100とする指数にて示した。この指数値が大きいほど氷上制動性能が優れていることを意味する。
