"Let's talk about getting a flat. You've probably heard it before, that unfortunate hiss that happens when you know you have a flat tire. In mountain biking, particularly if you don't have rear suspension and you are running tubes, tires and tubes which is more common than tubeless tires, you will hear that hiss in that rear tire because your rear tires has compressed so much, the tube has exploded on both sides and it is called snake bite from the two holes you get in that tube. But that is besides the point. What you know you have got to do is you have to get back on the road and that you do that by throwing in a new tube. So let's show how to do that. You hear the hiss, right? I am going to have to simulate it because my tire is perfectly inflated right now, the hiss of course of air escaping from your tire. Sounds like that, doesn't it? Ahh and you are bummed, your ride is over or so you think. Your friends are taking off, you are yelling, hey come back. So you have got to get that tire off, what you want to do is shift into the smallest cog, aka your highest gear in the rear. That makes it a lot easier to get that tire off. Let's see do that shift, never mind the skid, try not to do that. Make sure your brakes are disengage, if you are using rim brakes you need to make sure that the brakes are disengaged and it is very simple to do. Loosen that quick release on that back wheel and spin it off a couple of spins, boom, boom, boom. And you just kind of let that wheel fall right out. Ah-ha, got your wheel off, that is what you need. Just set the bike aside, be nice to it, you paid a lot for it you don't want it to be all scuffed up. You may have to use what is called a tire lever or a series of tire levers. Often times you want to make sure you carry probably at least two of these with you. The way this usually works is by just hooking one of them, hooking one of them getting the tire bead to come over the rim, which is what you need, you need that tire to come off the rim or you are just seeing this hopefully cause this is already off. And you do that several times in succession with different parts of the tire to allow you to pry that tire off. And there you go, your tire is off."
