図1に示されたタイヤを製作した。このタイヤのサイズは、190/55R17であった。このタイヤのコードの諸元が、表1に示されている。このコードは、4本のフィラメントからなる単撚りの構造を有する。このことが、「コード構造」の欄に、「1×4」として示されている。このコードのフィラメントの直径ψは、0.25mmとされた。このタイヤでは、距離WCの距離WBに対する比(WC/WB)は40%であった。
比(φ/ψ)及び初期伸びを表1の通りとした他は実施例1と同様にして、比較例1のタイヤを得た。このタイヤでは、コードのフィラメントは、きつく巻かれている。コード間の隙間は、実施例1と同じとされた。これは、従来のタイヤである。
比(φ/ψ)を表1の通りとした他は実施例1と同様にして、実施例2のタイヤを得た。
初期伸びを表1の通りとした他は実施例1と同様にして、実施例3−4のタイヤを得た。
コードの構造を表1の通りにした他は実施例1と同様にして、実施例5のタイヤを得た。
上記タイヤを正規リム(リムサイズ=MT6.00)に組み込み、排気量が1000ccであるスポーツタイプの二輪自動車の後輪に装着した。その内圧が290kPaとなるように、空気を充填した。前輪には、市販のタイヤ(サイズ:120/70R17)を装着した。この二輪自動車を、その路面がアスファルトであるサーキットコース及び市街地で走行させて、ライダーによる官能評価を行った。評価項目は、乗り心地及び耐バックリング性である。この結果が、比較例1を100とする指数で、表1に示されている。乗り心地及び耐バックリング性のいずれも、数値が大きいほど優れている。数値が大きいほど好ましい。
タイヤの質量を計測した。この結果の逆数が、比較例1を100とした指数で表1に示されている。数値が大きいほど、質量が小さいことが示されている。数値が大きいほど、好ましい。
バンドの形成に必要なコストが計算された。この結果の逆数が、比較例1を100とした指数で表1に示されている。数値が大きいほど、コストが小さいことが示されている。数値が大きいほど、好ましい。
