Carbon Wheel Heat Bending
To answer your questions


No, they are not safe to ride due to risk of the tube blowing out or the tire rolling off the rim.
No, I do not think they are repairable (at home). If they were repaired I would not trust them again.


I believe that this item is not fit for the purpose of a bicycle wheel.

It should be returned to the place of purchase on those grounds and a replacement or refund sought.
