上記のゴム組成物を用いて、50Kgf/cm2の圧力下で160℃、20分間のプレス加硫により厚さ1mmのゴムシートを作成し、JIS K7126に記載の差圧法(A法)に準拠し空気透過性比を測定した。比較例1を100とする指数表示で示し、値が小さいほど空気透過率が低く良好である。
各タイヤのタイヤ周方向と径方向とから採取したインナーライナーゴムを0.3mm厚×5mm幅×10mm長の短冊状試料に調製し、動的粘弾性スペクトロメーター((株)上島製作所製)を用いて、初期歪10%、動歪5%、周波数15Hz、雰囲気温度23℃において、各試験片についての動的弾性率E’を測定した。
各ラジアルタイヤ4本をJIS規定の標準リムを用いて空気圧200KPaに調整し、「GOLF IV」に装着し、出願人所有のタイヤテストコースの操縦安定性評価用Dry路面にて、2名乗車時の操縦安定性を3名のテストドライバーによって官能評価した。比較例1を基準に「±0」として、比較例1よりもやや良い(ドライバーには操縦安定性の有意差が分かるが、同乗者には分からないレベル)を「+1」、良い(同乗者にも分かるレベル)を「+2」、やや劣る(ドライバーには操縦安定性の有意差が分かるが、同乗者には分からないレベル)を「−1」、劣る(同乗者にも分かるレベル)を「−2」として表に示した。

Claims (2)
- ブチルゴム及び/又はハロゲン化ブチルゴム40重量部以上とジエン系ゴムとからなるゴム成分100重量部に対し、シンジオタクチック−1,2−ポリブタジエンを1.0重量部以上、3.0重量部未満含有するゴム組成物を所定の厚みに圧延加工しインナーライナーに用いたものであって、
圧延加工することで結晶性のシンジオタクチック−1,2−ポリブタジエンが列理方向に配向するようにし、また、この後の加硫成形により得られるインナーライナーには、この結晶性のシンジオタクチック−1,2−ポリブタジエンにより異方性を持たせたものであり、
圧延加工の際の列理方向を、加硫成形の際のタイヤ周方向に沿った方向とすることにより、前記インナーライナーのタイヤ周方向の動的弾性率E’pとタイヤ径方向の動的弾性率E’rとの比(E’p/E’r)が1.1以上となるようにした
ことを特徴とする空気入りタイヤ。 - ブチルゴム及び/又はハロゲン化ブチルゴムが、ゴム成分100重量部中に50〜95重量部含まれることを特徴とする請求項1に記載の空気入りタイヤ。
