How to detect whether the patent of tire pattern appearance is infringing?

I can only search bit by bit. If I want to authorize, it's simple. I can directly provide it to the patent office for authorization with the six-dimensional view. As long as the format is correct, I will generally authorize it, because in China, the design patent is only a formal examination. Only when there is a lawsuit or contradiction, the patent office will compare two patents or look at the application time.
