Ignore how she tells you to apply the glue back on the new tires. Here is my process...
After installing the tire, roll it around while squeezing it. You're trying to get the tire in its "free state", meaning you want the tire to relax, and not be stretched more here than there.
Spin the wheel on an axle or something and check for wobble and runout. Fix as necessary.
Then, when you have it as perfect as you can get it, gently pull the bead away, trying not to affect the tire's position, and use a needle tip on your tire glue bottle to apply the glue. You don't need much. You can also put some tire bands on if you want.
