Description
図1は、本発明の一実施形態を示すタイヤ1のトレッド部2の展開図である。本実施形態のタイヤ1は、例えば、乗用車用の空気入りタイヤであって、とりわけ公道走行が可能でありかつサーキット等でのスポーツ走行にも適した高性能タイヤである。
装着リム:16×6.5J
タイヤ内圧:230kPa
テスト車両:排気量2000cc、FR車両
タイヤ装着位置:全輪
上記テスト車両でドライ路面を走行したときの後輪のグリップ感が、運転者の官能により評価された。結果は、比較例を100とする評点であり、数値が大きい程、後輪で優れたグリップ感が得られ、接地圧が小さい状況でも優れたグリップが発揮されていることを示す。
上記テスト車両で、水深5mmかつ長さ20mの水たまりが設けられた半径100mのアスファルト路面を走行し、前輪の横加速度(横G)が計測された。結果は、速度50〜80km/hの平均横Gであり、比較例1の値を100とする指数で示されている。数値が大きい程、ウェット性能が優れていることを示す。
テスト結果が表1に示される。なお、表1において、距離L6が負の値の場合、第2傾斜溝の内端が第1傾斜溝の湾曲点のタイヤ軸方向に外側に設けられている態様を示している。
3 主溝
5 ショルダー陸部
10 傾斜溝
11 第1傾斜溝
12 第2傾斜溝
15 湾曲頂点
