I bought four wheels in an auto repair shop from Yongkang Zhetai Aluminum Alloy Company. After more than half a year's use, the edge of the inner ring of a front wheel fell off 10 cm long, and the width was about 2 cm long. I don't know when it fell. The tire was flat, and the problem was discovered when it was repaired. The aluminum alloy is too thin. This company is purely based on profit, not quality. Do you dare to get on the highway with such wheels? This is a matter of life and death. What is the conscience of your company? I advise consumers to be optimistic about the brand.
