Sichuan Haida Rubber Group Co., Ltd. has exported new all-steel mobile-home tire models developed and produced by it to the U.S.
The new models have three types of treads and the progress from development to production took nearly nine months.
Researchers made progresses in tread, structure design, formula design and techniques.
In addition, to prevent flawed tires with invisible bubbles, the company imported a ZEISS holographic bubble detector. And the performance of the tires are good.
