The weirdest thing is that the seating is uneven on both sides, causing a depression in the tire. This is happening on both the front and rear tires.
I am thinking that it has nothing to do with the tire, but rather that the inner tube is not inflating evenly all the way around. Perhaps the place where there is a depression in both tires is a spot where the tube is not inflating as much as elsewhere. That's my theory, any others?
Also, any ideas on how to fix it?
It is not an inner tube problem. I guarantee that with 80-100 psi of air pressure, your tube is conformed completely to the inner cavity of the tire/rim. If not, there would be a big hole in it. Your problem is the bead of the tire is a little small compared to the rim. You may be able to get it to pop into place by lubricating the bead with soapy water and overinflating the tire. You can also try whacking the tire against the driveway on the side of the tire where it's low to help "pull" it out. There's also a tool that grabs around the tire to let you help pull it out.
