I bought a wheelset (eighth inch amelia's) that came with tires and tubes pre-installed. When I started pumping them up, I noticed the bead wouldn't stay seated. I know this is usually due to part of the tube being between the tire and the rim, but I checked all around and that isn't the case. It looks to me like the tire is actually stretched out or warped. Is there any way to get this to mount up evenly?
Yes, I know these are dirt cheap tires, but I would at least like to get a few miles out of them.
