Removed and reinstalled the rear tire today (26x 1 3/8 on a Raleigh Sports). The bead is not seating in one area and it has a flat spot. Deflated and powedered it up like a new born but still has the same issue. I did install a new tube and rim strip. I thought that I read some where that over inflating and letting it sit does the trick. am I missing anything else?

Thanks.
