Any of the current Chinese manufactured bandsaws are not really a bandsaw so much as a bandsaw kit that might happen to work out of the box. Your wheels were certainly not balanced if you had to fight alignment problems that often, and this dent is a likely explanation – a 1/4 inch blade simply cannot withstand enough force to cause that kind of inward collapse, even if all the force was optimally directed which it simply isn’t.

I would not bother re-truing the wheel, it probably was never true to begin with and would be a hard place to start from. Just don’t expect a new wheel to be perfect either. Pick up one of the books or articles (Duginske, Bird and Fortune all have good ones) that walk through a tune-up, spend an afternoon or so, and never worry about it again.
