Abstract
Description
図1は、本実施形態の自動二輪車用タイヤ(以下、単に「タイヤ」という場合がある。)1の正規状態におけるタイヤ回転軸を含むタイヤ子午線断面図である。正規状態とは、タイヤ1が正規リムにリム組みされかつ正規内圧が充填された無負荷の状態である。本明細書では、特に断りがない限り、タイヤ1の各部の寸法等は、正規状態において特定される値である。
タイヤサイズ:
前輪:120/70ZR17
後輪:160/60ZR17
リムサイズ:
前輪:MT3.50×17
後輪:MT4.50×17
内圧:
前輪:225kPa
後輪:250kPa
テスト方法は、次の通りである。
試供タイヤが、排気量400ccの自動二輪車の後輪に装着され、乾燥アスファルト路面を有するテストコースでテスト走行が実施され、「過渡特性」、及び、「フルバンク走行時の安定性能」が、テストライダーの官能により評価された。結果は、比較例1を100とする評点で表示されている。数値が大きいほど良好である。
テスト結果が表1に示される。
