Therefore, a kind of air-inflation tyre is disclosed in following patent documentation 1, its objective is when alleviating tire weight, improve the lateral stiffness of tire, thereby improve driving stability, its casingply is through the tire axial lateral surface of bead-core, in tire radially inner side inboard extension from the tire axial lateral of bead core.According to this air-inflation tyre, when the distortion of tire, by the lateral surface side in bead part, i.e. the position of tension force effect has casingply, can improve the lateral stiffness of tire, therefore can improve driving stability.
But, the airtyred structure of patent documentation 1 is that the end of casingply is below the bead core of the tire radially inner side of bead core, ended by card inboard the extension also of tire axial, because the interior pressure during sulfidization molding, when tension force acts on plies cords, card ends a little less than the power, so casingply might break away from from bead core.
In addition, disclose a kind of air-inflation tyre in following patent documentation 2, its casingply has carcass plies main part and carcass plies return portion; Described carcass plies main part arrives the lateral surface of bead core and reaches its radial direction outward flange; Described carcass plies return portion links to each other with this carcass plies main part, and by centering on the bead-core of bead-core bottom surface and tire axial lateral surface and medial surface around portion at bead core around portion's connection setting, thereby also only block in bead part around bead core and bead-core, described bead core is sagging around the tire axial lateral surface of portion from described outward flange to bead core, and through the circumferential inner peripheral surface of tire of bead core, erect at the tire axial medial surface of bead core.
According to the air-inflation tyre of patent documentation 2, because casingply only blocks securely in bead part the disengaging of casingply in the time of can suppressing sulfidization molding.But the end of casingply is the tire central part radially that the end of carcass plies return portion is positioned at the bead-core medial surface, thereby produces diff-H, and stress is concentrated and cracked easily.
In addition, the air-inflation tyre of following patent documentation 3, tire radial outside at bead core has the inboard bead-core in footpath and the outside, footpath bead-core, and after casingply was rolled from the inboard laterally around bead core, it was rolled end and is sandwiched between the inboard bead-core in footpath and the outside, the footpath bead-core.By this structure, the card that can improve casingply ends power, and the disengaging of casingply when suppressing sulfidization molding simultaneously, can prevent that the end of rolling of casingply from separating, and improves bead part durability on every side.
But, the air-inflation tyre of patent documentation 3, because its structure is that casingply is rolled from the inboard laterally around bead core, therefore there is not casingply in the lateral surface side in bead part, can't fully improve the lateral stiffness of tire.And, because the outside, footpath bead-core increases weight, therefore may cause harmful effect to exercise performance.
