  1. Push all air possible out of the tube, pressing down on the ground and on several places on the tire with your arms/hands.
  2. Push both tire beads toward the center of the rim well all the way around the rim (to make sure bead has not stuck to the rim)
  3. Starting at the area of the rim OPPOSITE the valve, typically where the seam or reflector would be, push one side/bead toward the center of the rim using both thumbs.
  4. Using both hands and working in opposite directions with thumbs and palms “scrub” or push the tire toward the center of the rim until you are near the tire valve.
  5. You should now be able to more easily use the tire levers to get the bead over the rim.
Installation:
  1. Put a small amount of air in the tube and mount one side/bead of the tire. Some put the tube into the tire before mounting, some mount the 1st bead and then put the tube in. I recommend mounting the tire so that the part of the tire label that gives the pressure is next to the valve and on the right side of the bike (mechanics will thank you) but it’s your choice whether you do that or something else.
  2. Starting at the area of the rim OPPOSITE the valve, typically where the seam or reflector would be, push the bead over the rim and toward the center of the rim with your thumbs.
  3. Using both hands and working in opposite directions with thumbs and palms “scrub” or push the bead over the rim and toward the center of the rim until you are near the tire valve. Push any more air that you can out of the tube.
  4. You should now be able to push the last section of bead over the rim. Push the valve up into the tire, make sure there is no tube caught underneath the bead either near the valve or elsewhere.
  5. Inflate to about 30-40psi, check the bead line (raised ridge of rubber near the rim edge to make sure it is equidistant everywhere.
  6. Continue to inflate and monitor to full pressure.
If you still have problems you can use toe straps or cable ties to hold one side of the bead in place near the valve stem while working on the other side, and can
wow the post is useful!
