This study aims to analyze tire wear particulate matter (TWP) from tread rubber with different formulations and to compare the concentration of TWP with different wear devices. The TWP generated during the abrasion of truck and bus radial (TBR) tires were examined, and the effect of using different types of rubber and carbon black (CB) were investigated. When natural rubber (NR) was solely used as the tire tread rubber material, there was a higher concentration of 5-10 µm TWP. However, when the tread formulation consisted of NR mixed with butadiene rubber, the TWP concentration decreased. Changing the type of CB also reduced the amount of TWP in the 2.5 µm size range. The TWP concentration in the specimens increased with increasing speed and vertical load. The TWP generated during the abrasion tests using wear testers and tire simulators exhibited similar trends. These findings suggest that modifying tire tread formulations can effectively control the distribution and amount of TWP generation.
本研究旨在分析不同配方胎面胶产生的轮胎磨损颗粒物（TWP），并比较不同磨损装置下TWP的浓度。研究了卡车和客车子午线（TBR）轮胎磨损过程中产生的TWP，并考察了使用不同类型橡胶和炭黑（CB）的影响。当仅使用天然橡胶（NR）作为轮胎胎面胶材料时，5-10μm的TWP浓度较高。然而，当胎面配方由NR与丁二烯橡胶混合组成时，TWP浓度降低。改变CB的类型也减少了2.5μm尺寸范围内的TWP量。试样中的TWP浓度随速度和垂直载荷的增加而增加。使用磨损试验机和轮胎模拟器进行磨损试验时产生的TWP呈现出相似的趋势。这些发现表明，修改轮胎胎面配方可以有效控制TWP产生的分布和数量。
