Tire rolling radius and load radius test method considering tread wear

The invention relates to a method for testing the rolling radius and the load radius of a tire in consideration of tread wear. The invention relates to the technical field of tire rolling radius and load radius tests. Load level, air pressure level, speed level, slip angle level and camber angle level are set; setting each factor as a specified level according to the sequence number, recording the height of the tread pattern, and testing the rolling radius and the load radius until the tests in all the sequence numbers are completed; rolling radius and load radius data obtained by the test are processed by adopting a partial least square regression method, and respective regression models are established; 本发明是一种考虑胎面磨损的轮胎滚动半径和负荷半径的试验方法。本发明涉及轮胎滚动半径和负荷半径的试验技术领域，设置载荷的水平，设置气压的水平，设置速度的水平，设置侧偏角的水平，设置外倾角的水平；按序号将各个因素设置为指定水平，记录轮胎花纹高度，进行滚动半径和负荷半径的测试，直至完成所有序号内的试验；对试验得到的滚动半径和负荷半径数据，采用偏最小二乘回归方法进行处理，建立各自的回归模型。
