Reinstalling tire after replacing inner tube, how important is it that tire bead is even along rim?
An uneven bead can indicate the tube is trapped under the bead. This can cause blowouts or pinch flats. Let the air almost all out of the tube until you can push the tire back away from the bead, then push the tire back from the bead and look all the way around on both sides to ensure the tube is not under the bead, but instead all the way inside the tire. If it isn't, work the tube back into the tire all the way around on both sides. Once you're satisfied the tube is fully inside the tire, reinflate. Also, ensure the tire is the right size for this rim.
