How to Remove the bike tire or at least half of it ?

The tire is easier to remove if you release any remaining air from the tube. You release the air from the tube through the valve. There are two main types of valves:

• Presta valve: A Presta valve is thin and all metal. Many road bikes use Presta valves, which can handle greater pressure and leak less than Schrader valves.
• Schrader valve: The Schrader valve is fat, like what you’d see on a car tire. Schrader valves are easier to pump up than Presta valves; you can fill them up at a gas station.

Some bike pumps are designed for either Presta or Schrader valves while some are reversible and work with both. If you aren’t sure what you need, ask for help in your local bike shop.

If you’re putting air in a tire at a gas station, be careful not to overfill it — the tire could explode.

If you have a Presta valve, unscrew and press down on the tip of the valve. If you have a Schrader valve, insert the tip of a tire lever into the center of the valve while squeezing the tire to allow air to escape.

Then, using the tire levers, try to lift one side of the tire off the rim while leaving the other side in place. Here’s how:

1. Pinch the tire all the way around the rim to move the edge (or bead) of the tire away from the rim.
2. Slide the flat end of the first tire lever between the rim and the bead of the tire under it. Make sure to use tire levers, not flathead screwdrivers — screwdrivers have sharp edges that can puncture the tire. In a pinch, the handles of silverware can work.
3. Pull the lever down so that the bead rises up and over the rim.
4. Hook the bottom of the lever to a spoke to keep it in place.Some tires are very tight and you’ll need extra room, so don’t hook the first tire lever to the spoke until you get the second lever slid under the tire.
5. A few inches away, repeat steps 2 and 3 with the second tire lever.
6. Repeat steps 2 and 3 with the third lever, but instead of hooking the lever to a spoke, start dragging the lever around the wheel away from the first and second levers. You should notice the tire becoming looser until the entire side pops off the rim.
7. Before removing the inner tube from the wheel, pump it up with a little extra air. Later, when you have to look for the puncture, you’ll need some air in the tube and it’s easier to pump up the tube while it is still on the wheel.
8. While the tire is still on the rim, reach under it and pull out the tube.
9. When you reach the valve, lift up the tire and pull the valve through the rim, being careful not to damage it.

Note the position of the tube in relation to the tire so when you find the hole in the tube it will be easier to locate the cause (glass, a nail, a thorn), if it’s still embedded in the tire.
