摘要: A precure tread for a tire has surface grooves facing a tread face, rear grooves facing a crown portion of a base tire, and a passage for communication between the rear grooves to atmosphere. The groove bottom of the rear grooves is located at a higher level than a groove bottom of the surface groove in the radial direction. The tire durability can be considerably improved when this precure tread is applied to a new tire or a retread tire.
摘要翻译: 用于轮胎的预固化胎面具有面向胎面的表面槽,面向基轮胎的胎冠部的后槽和用于在后槽与大气之间连通的通道。 后槽的凹槽底部位于比表面槽的槽底部沿径向更高的位置。 当将该预固化胎面施加到新的轮胎或翻新轮胎时,轮胎耐久性可以显着提高。
