Why do the drums appear in the tires? Jan 11, 2019

Why do the drums appear in the tires?

There are two kinds of tying drums and blasting drums, and there are three kinds of blasting drums. The crown emptiness, shoulder space and sub-port are empty. The crown void is mainly characterized by the tread surface (referred to as the crown surface), that is, the tread top delamination.

The main reason is that the tire pressure is too large during the use of the tire, so that the tire landing area is reduced, the tire is worn early, and the tire temperature is increased due to rolling acceleration or tire heat dissipation during tire use.
