具有胎面的气动轮胎具有槽面积比

Pneumatic tire with tread having groove area ratio
Abstract:
In a pneumatic tire, a difference Gs−Ge falls in a range of Gs−Ge≧0.10, where Gs is a groove area ratio for a wear rate 0% and Ge is a groove area ratio for a wear rate 100%. Further, a groove area ratio G for a wear rate 20% falls in a range of (Gs−G)/(Gs−Ge)≧0.30, and a groove area ratio G for a wear rate 35% falls in a range of (Gs−G)/(Gs−Ge)≧0.50.
Abstract(Chinese):

在充气轮胎中，差Gs-Ge落在Gs-Ge≥0.10的范围内，其中Gs是磨损率为0％的槽面积比，Ge是磨损率为100％的槽面积比。 此外，磨损率20％的槽面积比G落在（Gs-G）/（Gs-Ge）≥0.30的范围内，磨损率35％的槽面积比G落在（ Gs-G）/（Gs-Ge）≥0.50。
