The invention discloses a tire, a wheel and a vehicle. The tire comprises a body and a grease layer. The body comprises a tire crown part, a tire shoulder part and a tire side part, the tire shoulder part is connected with the tire crown part and the tire side part, and the tire crown part is provided with a ground plane; the grease layer is arranged on the inner surface of the tire shoulder part, and the two sides of the grease layer extend to the inner surface of the tire crown part and the inner surface of the tire side part respectively; and/or the grease layer is arranged on the inner surface, far away from the tire crown part, of the tire side part. The grease layer is arranged in the body, so that the stress on the inner surface of the body is dispersed by the grease layer, especially at the joint of the inner surfaces of the tire shoulder part, the tire crown part and the tire side part which are easy to concentrate stress. When the body provided with the grease layer is subjected to a large impact load, the acceleration in the Z direction is reduced, so that the safety characteristic design threshold value of the tire is improved. Therefore, the safety and the stability of the vehicle are improved, and the tire is not prone to functional failures such as bulging, cracking and tire burst.

    本发明公开了一种轮胎、车轮和车辆。轮胎包括本体和油脂层。本体包括胎冠部、胎肩部和胎侧部,胎肩部连接胎冠部和胎侧部,胎冠部具有接地面;油脂层设置在胎肩部的内表面并且油脂层的两侧分别延伸至胎冠部的内表面和胎侧部的内表面;和/或,油脂层设置在胎侧部远离胎冠部的内表面。通过在本体中设置油脂层,本体的内表面的受力得以被油脂层分散,尤其是易应力集中的胎肩部、胎冠部和胎侧部的内表面的连接处。设置油脂层的本体在受到大的冲击载荷的状态下,Z向的加速度得以降低,这使得轮胎的安全特性设计阈值得以提高。因此,车辆的安全稳定性得以提升,轮胎不易发生鼓包、开裂、爆胎等功能失效。
