Abstract
Description
JIS D 4234(ISO28580)に規定された試験方法に準じて転がり抵抗を測定した。比較例1の結果を100として指数で評価し、数値が小さいほど転がり抵抗が小さく、良好であることを示す。
タイヤを車両(3000ccクラスのSUV)に装着して評価路面を走行し、旋回や制動、加速試験を実施してドライバーによる官能評価を行った。比較例1の結果を100として指数で評価し、数値が大きいほど操縦安定性能に優れることを示す。
タイヤを車両(3000ccクラスのSUV)に装着して乾燥した評価路面を走行し、ドライバーによる官能評価を行った。比較例1の結果を100として指数で評価し、数値が大きいほど乗心地性能に優れることを示す。
前述の実施形態においてリムストリップゴムの形態を異ならせ、それぞれ比較例1〜3及び実施例1とした。比較例1は、リムストリップゴムの上端がタイヤ最大幅位置に到達しない構成とした。比較例2,3は、リムストリップゴムが、界面の露出位置からタイヤ径方向外側に向かって厚みを漸減させた後、一定の厚みでタイヤ径方向に延びる構成とした。実施例1は、図1,2で示した構成とした。その他のタイヤの構成については、各例において共通である。表1において、厚みTbは、ビードフィラーの上端位置におけるリムストリップゴムの厚みである。
