Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 踏面剛性を効果的に増加させる。 【構成】 タイヤ周方向に対して25°〜90°の範囲の角 度でのびるコードからなる少なくとも一枚のカーカスプ ライ3aと、実質的にタイヤ周方向にのびるコード4b, 4c からなる少なくとも一層のベルト層4aとを具えるタイヤ である。トレッド幅とほぼ等しい幅を有する少なくとも 一層のベルト層4aを二種類のコード4b, 4cにより形成 し、一方のコード4bの、約140 ℃における熱収縮率を、 他方のコード4cのそれの2倍以上とする。 (57) [Summary] [Purpose] To effectively increase the tread rigidity. [Constitution] At least one carcass ply 3a consisting of cords extending at an angle in the range of 25 ° to 90 ° with respect to the tire circumferential direction, and cords 4b, 4c extending substantially in the tire circumferential direction. And a belt layer 4a of at least one layer. At least one belt layer 4a having a width substantially equal to the tread width is formed by two types of cords 4b and 4c, and one cord 4b has a heat shrinkage ratio at about 140 ° C. It is more than twice that of the other code 4c.
