サンプルの調製
表Iに示す配合において、加硫促進剤と硫黄を除く成分を1.7リットルの密閉型ミキサーで6分間混練し、150℃に達したときに放出してマスターバッチを得た。このマスターバッチに加硫促進剤と硫黄をオープンロールで混練し、ゴム組成物を得た。
tanδ(60℃):JIS K 6394準拠し、粘弾性スペクトロメーター(東洋製機製作所製)を用いて測定し、その結果を比較例1の値を100として指数表示した。この値が小さいほど、低発熱性(即ち低燃費性)に優れることを示す。
tanδ(0℃):JIS K 6394に準拠し、粘弾性スペクトロメーター(東洋製機製作所製)を用いて測定し、その結果を比較例1の値を100として指数表示した。この値が大きいほど、ウェット性能に優れることを示す。
転がり抵抗:転がり抵抗試験機を用いて試験タイヤの転がり抵抗を測定し、その結果を比較例1の値を100として指数表示した。この値が小さいほど、低燃費性であることを示す。

○…ロールへやや密着するが、シート取上げ可能。
◎…ロールへの密着はあまりなく、きれいに剥がれる。
