Where can I repair the pot and the wheel in Chifeng?
It's beyond repair! If it is an outer rim card or a spoke and bowl card, check whether there are cracks on the lower periphery (for safety reasons, do nondestructive testing). If there are cracks, they must be replaced. If there are no cracks, it will not only affect the appearance, but will be fine as long as there is no air leakage! Furthermore, I suspect that the mechanical properties of your wheel hub are not good, at most, it is deformed. Why is it stuck? Suggest a change)
