Most tire properties are closely related to the pattern deformation. In order to explore the relationship between tire performance and defined deformation parameters in the contact area between the pneumatic tire and road surface, ten types of 205/55R16 passenger car radial (PCR) tires were selected as the research objects. Using VIC-3D non-contact strain measurement system and by subdividing the contact area, the pattern deformation in contact area under vertical load was tested, and the relevant deformation parameters of the contact area were extracted. Correlation analysis was used to establish the relationship between the identified deformation parameters and tire performance indicators. Then an evaluation method of tire performance based on the deformation parameters was proposed, as well as clarification of the contradictory mechanism between tire noise, rolling resistance and dry grip performance. While the results indicate tire noise having a significant negative correlation with radial deformation in the contact area, rolling resistance coefficient gave a significant positive correlation with its equivalent strain in the XY plane of the contact area, and dry braking distance positively correlates with tensile strain in the Y direction of contact area and negatively correlates with tensile strain in the X direction of the contact area.

大多数轮胎性能与花纹变形密切相关。为了探索充气轮胎与路面接触区域的轮胎性能与定义的变形参数之间的关系，选择了十种205 / 55R16乘用子午线（PCR）轮胎作为研究对象。使用VIC-3D非接触应变测量系统，通过细分接触面积，测试了垂直载荷下接触区域的图案变形，并提取了接触区域的相关变形参数。相关分析用于建立识别的变形参数和轮胎性能指标之间的关系。然后提出了基于变形参数的轮胎性能评估方法，并阐明了轮胎噪音，滚动阻力和干抓地力之间的矛盾机理。虽然结果表明轮胎噪声与接触区域的径向变形具有显着的负相关性，但滚动阻力系数与其在接触区域的XY平面中的等效应变具有显着的正相关性，而干制动距离与轮胎的拉伸应变呈正相关。接触区域的Y方向与在接触区域的X方向上的拉伸应变负相关。
