Trick to mounting tires?
Is there a trick to mounting tires so that they are even all the way around the rim? The tires always seems to sit further in the rim and further out in some places, giving the appearance that it is hopping when it is spun. My wheels are totally true by the way.

Are you deciding this by the bead on the tire? There is usually a line molded into the tire about where the tire should sit against the rim. Is that flush all the way around?

Depends a little on the tires. Sometimes just pushing the valve stem inward before inflating the tire is all that it takes (if that's where the high point happens to be) Some tires (generally cheap ones) seem to be a little bit oversized and defy even mounting no matter what I do.

That happens when the tire bead is not evenly seated in the rim. When mounting inflate the tube wigth enough pressure to give the tire shape and hold (about 20 psi). Then run your hands around the wheel stopping to grip the tire and rotate your wrists back towards you like you are trying to pull the tire off the rim.
This motion is similar to kneading or massaging someone's shoulders. It help set the bead evenly. flip the wheel around and do the other side as well.

There was a Danielle that did a super long ride last week. At least I thought it was a Danielle. I probably have it wrong.
Sprinkle baby powder inside the tire before putting it on. After you put the tube in, push the second bead in all the way around. Then starting at the valve, peek inside the tire at the bead and be sure that the tube is not caught between the bead and the hooked portion of the rim. (You shouldn't really see the tube at all.) Put in about 5 pumps of air, just a few psi. This is the point when the bead meets, or engages with, or interfaces with, the hooked part of the rim. That's what keeps it on. Spin the wheel around a bit, and it should all be OK. Fill it the rest of the way.
