Bead breaking
If tire has been on a long time: possibly, trouble.
If you are with two bikes: use the side stand of the bike w/o flat tire to break the bead on the handicapped one: place end of sidestand on th tire wall, lift bike and voila.
If you are alone: remove wheel. Remove air (essential obviously). Put wheel down flat. Jump on tire wall with your heavy boots.
If that does not work; open bead as far as it goes and pour in water as lubricant. Repeat jumping.
A hammer on the sidewall will also work. Keep tension on the bead with your tire lever and hit the sidewall with a hammer, as close to the rim as possible.
If that does not work; install wheel again. Drive 10 meters ... voila.
Before you travel, as you practice tire changing anyway, install th tire with this special tire grease that professionals use to lubricate the edge of the tire to make it fit in place easier. This stuff avoids that the bead sticks to the rim after a while.
All this applies to tubed wheels. I have no experience with tubeless.
