Put the wheel on the ground, seat the tire at the top and push down on both sides at one time, trying to stretch the tire down. Then work the bead onto the rim. When you get to the last, most difficult part, instead of using your thumbs or a lever, hook your fingers over the rim and use the top of your palm to roll the bead over.
