The invention relates to the technical field of tires, in particular to a tire with a curvature-continuous tire crown profile curve, which comprises a tread curve, a tire shoulder curve, a tire side curve and a tire bead curve which are connected in sequence, wherein the driving surface curve adopts a secondary curve with continuous curvature; the driving surface curve is provided with a starting point control point A, an end point control point C and a middle control point B, and the driving surface curve passes through the middle control point B by taking the starting point control point A as a starting point and takes the end point control point C as an end point; a tangential control line L1 of the driving surface curve at the starting point control point A is parallel to the axial direction of the tire at the starting point control point A and is tangent to the driving surface curve; and a tangential control line L2 of the driving surface curve at the end point control point C is tangent to the driving surface curve and the tire shoulder curve at the end point control point C. The tire has the effect of effectively improving crown grounding imprint and grounding pressure distribution.

    本发明涉及轮胎的技术领域,尤其是涉及一种具有曲率连续轮胎冠部轮廓曲线的轮胎,其包括依次连接的行驶面曲线、胎肩曲线、胎侧曲线、胎圈曲线,所述行驶面曲线采用曲率连续的二次曲线,所述行驶面曲线具有起点控制点A、终点控制点C、中部控制点B,所述行驶面曲线由起点控制点A为起点通过中部控制点B并以终点控制点C为终点,其中,所述行驶面曲线在起点控制点A处的切向控制线L1在起点控制点A处与轮胎轴向平行且与行驶面曲线相切;所述行驶面曲线在终点控制点C处的切向控制线L2在终点控制点C处与行驶面曲线相切且与胎肩曲线相切。本发明具有有效改善冠部接地印痕及接地压力分布的效果。
