No clue abouts beads and hooks, so I should do some research. Ha

beads are the two outside lines on the tire itself, hooks are the bottom of the ends of the tire where when you inflate the tube, they hook into the lip of the rim.

Oh, well that is easy enough! Now, to re-read your post! :) Thank you.

fyi I second everything olds' just said about your wifes wheel. The only thing I could really add, is it could possibly be you have the tube twisted at that point and it's creating a hump pushing the tire up, that is extremely not good. (probably isn't the problem though)
