You're here with Salt Lake City Bicycle Collective. I'm online at www.slcbikecollective.org. We
are here on behalf of Expert Village today and I'm going to show you how to change a
flat. Once you have everything in there, you can go ahead and reinstall it back into the
rim. You want to make sure that the rim strip (the little rubber piece that is inside here)
is lined up and covering all of the nipples that are sticking out of the top. Sometimes
you might need to realign that piece because it may have come out of place when you took
the original one out. So, you line that up and get the original valve stem to come out
through here. It's important that the valve comes through here nice and straight. If it's
at an angle, sometimes it can tear the side of the valve stem which can result in giving
you another flat tire. You are going to go ahead and get this lined up. Get it started
on here. Sometimes it helps if it's up against the bench like this. It gives you a little
bit of room to push on it. I'm just going to work that tire all the way around until
you get to the end. Sometimes when you get to the end, you might want to let a little
bit of air out of it. That will help you get it back on there. Once you get everything
back on there, we are going to go ahead and throw a little bit more air into it; maybe
get it up to twenty, twenty five PSI. What you are going to do at that point is you are
going to make sure that the tire is seated. So I'm at about twenty there. I'm actually
going to pop this back off and double check. What you'll actually see has happened is that
it wasn't seated in this location, so now you are going to have the tire coming back
out. So, what you want to do is let a little bit of air out of that and push it back under
the rim so that it stays under there. We just do that by hand; by manipulating it. Just
squeeze that under there. You are going to get that all lined up and then finish by inflating
it and reinstall it into the bike.
