The invention relates to the technical field of tires, in particular to a wheel for improving tire bead pressure, which comprises a rim and a tire, and the radial section of the rim is sequentially provided with a rim edge and a bead fitting part from one end to the middle; the radial section of the tire comprises a tire side wall and a tire bead; when the outer side surface of the bead is attached to the top surface of the bead attaching part, a first preset included angle is formed between the outer side surface of the bead and the top surface of the bead attaching part; and when the outer side of the lower part of the sidewall is attached to the inner side surface of the rim edge, a second preset included angle is formed between the outer side surface of the lower part of the sidewall and the inner side surface of the rim edge. The angle between the bead and the rim is reduced by reducing the radius of the contact point chamfer of the tire, so that the bead and the rim are stressed more uniformly, the stress concentration is reduced, and the service lives of the tire and the rim are prolonged.

    本发明涉及轮胎技术领域,具体公开了一种改善轮胎胎唇压力的车轮,包括:轮辋和轮胎,轮辋的径向截面由一端向中部依次为轮辋边沿和胎唇贴合部;轮胎的径向截面包括胎侧和胎圈;当胎唇的外侧面贴合于胎唇贴合部的顶面时,胎唇的外侧面与胎唇贴合部的顶面成第一预设夹角;当胎侧的下部的外侧贴合于轮辋边沿的内侧面时,胎侧的下部的外侧面与轮辋边沿的内侧面成第二预设夹角。通过减小轮胎着和点倒角的半径,以减小胎唇和轮辋之间的角度,使胎唇和轮辋受力更均匀,达到减小应力集中提升轮胎和轮辋使用寿命。
