Knowing how to change a tire is a pretty useful trick and tip when it comes to being a mountain
biker because changing tire for preference is the same for changing tires when you get
a flat. So it always good to be prepare and know how to do this. With this specific tire
and wheel combination we see we have what is called a press valve it is a thinner valve
then what you would find in a car and instead of having a valve cap to have it close there
is a little threaded nut which as you can see the valve is close I push down on it no
air comes out. Now I open the valve and I push down on it air comes out so I'm going
to let all the air out. It takes while sometimes it helps if I push down on the tire a let
the air come out a little quicker.
You can hear it coming out it looks like we are pretty good.
