空気入りタイヤ

Pneumatic tire

Abstract

【課題】操縦安定性と排水性を両立させながら高速耐久性を改善するようにした空気入りタイヤを提供する。 【解決手段】ネガティブキャンバーを付与した車両に装着向きを指定して装着されるタイヤであってトレッド面の中央域に左右2本の周方向溝11、12に挟まれた中央陸部21を形成しその内側端部にブロック状陸部22及び外側端部にリブ状陸部23を形成し、内側及び外側のショルダーにブロック列24、25を形成した空気入りタイヤにおいて、前記左右2本の周方向溝のうち内側周方向溝11を車両に装着した状態で接地したときタイヤ周方向接地長さが最大になる領域に重なるように配置し、内側周方向溝11から中央陸部21の途中まで延長する第1傾斜副溝14をタイヤ周方向に間欠的に配置し、互いに隣接する3本以上の第1傾斜副溝14に交差し前記2本の周方向溝のいずれにも連通しない第2傾斜副溝15を配置してブロック状陸部22を形成する。 【選択図】図1
<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire improving high speed durability, while making steering stability and water drain property compatible. <P>SOLUTION: This tire is mounted on a vehicle imparted with a negative camber by designating the mounting direction. In the tire, a center land part 21 held by two right and left peripheral direction grooves 11 and 12 is formed in a center region of a tread surface, a block-shaped land part 22 is formed at the inside end part, and a rib-shaped land part 23 is formed at the outside end part. Block rows 24 and 25 are formed in shoulders at the inside and outside. In this case, the inside peripheral direction groove 11 of two right and left peripheral direction grooves 11 and 12 is arranged to overlap with a region where a tire peripheral direction grounding length becomes maximum when grounding the groove 11 in a mounted state on the vehicle, first inclined sub-grooves 14 extended from the inside peripheral direction groove 11 up to the midway of the center land part 21 are intermittently arranged in the tire peripheral direction, and a second inclined sub-groove 15 which intersects three or more first inclined sub-grooves 14 adjacent to each other and is not communicated with both of the two peripheral direction grooves 11 and 12 is arranged to form the block-shaped land part 22. <P>COPYRIGHT: (C)2007,JPO&INPIT
