对使用预成型胎面和使用普通胎面的轿车子午线轮胎进行了对比试验。试验结果表明，使用预成型胎面的轮胎，其胎面胶料在硫化过程中的流动受到控制，在轮胎横截面上的分布更加均匀，从而使动平衡差度大幅度降低，动平衡检测通过率得以提高
Contrast tests were conducted on car radial tires using preformed treads and normal treads. The test results show that the tire tread with pre-formed tread is controlled by the flow of vulcanization process and more evenly distributed in the tire cross-section so as to greatly reduce the dynamic balance and detect the dynamic balance Rate can be improved
