How do you remove a bicycle inner tube?

Answer 1

1. Remove wheel from bicycle*

2. Ensure tube is released of pressure

3. Using tire levers, remove tire from wheel

4. Discard old tube

5. Check wheel to ensure rim tape is still in place and no spokes are poking through. Also check for rust.

6. Inflate new tube very slightly (just enough to give it a little body)

7. Put first bead of tire back on wheel**

9. Insert tube inside of tire

10. Put second bead of tire back on wheel (careful not to pinch the tube between the tire and the wheel)

11. Put wheel back on bicycle*

*you may need to disengage / engage the brakes to do this

**when positioning the tire back on the wheel, try to put the markings on the tire that show how much to inflate the tire so they are even with where the stem will poke through the wheel. This will allow you to find your suggested pressure reading easier when you go to inflate it in the future.
First you need to get a screwdriver (preferably a flat head and a wrench. Then you must use the wrench to remove the tire from the bike. After that you must take the screw driver and work it under the actual tire ( the rubber outside layer) then pry the tire from the rim slowly (be sure not to bend the rim) then you remove the inter tube and then replace with the new one. After that you align the inflation tube properly then put the tire over top an pry it back into place, then replace the tire on the bike.
Although you usually need tire levers or a similar tool to remove a tire from the rim, usually you should be able to re-install the tire with your bare hands. If you try to pry the tire on using tools, you are very likely to wind up pinching the inner tube between the tool and the rim, puncturing it. It is usually helpful to have a little bit of air in the tube just enough to make it sort of round rather than flat. With presta-valve tubes, I usually just blow air into the tube by mouth. In the case of a brand new tube, it sometimes helps to stretch it out first. I do this by stepping into it and lifting away by hand. Start by fitting the valve of the inner tube through the valve hole. Loosely secure the valve using a valve cap or retaining ring so it won't fall back through the hole. If your valve is threaded for a retaining ring, don't tighten it down very far yet, just thread it on far enough that the valve can't fall out of the rim. With the tube dangling down along one side of the wheel, install one edge of the tire onto the rim, so that the tube is hanging out of the open side. This is usually pretty easy. Next, tuck the tube into the tire. It is best to start at the valve, work your way one third of the way around the tire, then go back to the valve and work around in the opposite direction. Once the tube is in place, you're ready to install the second edge of the tire. This is the hardest part of the whole process, and the hardest part of this is the very last segment. You should start at the valve, so that the valve won't be a complicating factor when you are trying to lift the last bit of tire bead over the edge of the rim. As you install the second edge of the tire, try to push it toward the middle of the rim channel, where the channel is deepest. This will give you more slack. Make sure that the tire bead is not sitting on top of the base of the valve. If it is, push the valve almost back through the rim to raise the reinforced patch at the base of the valve, and push the tire down around it. For the last few inches of tire bead, some considerable force may be needed to pop it over the edge of the rim. (Some rim/tire combinations are easier than others.) If it is giving you difficult, resist the urge to press the middle part over. Instead, work alternately from each end of the section you're trying to lift over. Going back and forth from side to side will usually get it. Most folks do this by holding the wheel horizontally, with the open side up. Wrap your fingers around over the tire to press on the bottom of the rim, while you push the tire either with your thumbs or with the heels of your hands. If you just can't get it by hand, here are some things to check: * Make sure the tire bead isn't sitting on top of the tube anywhere. * Make sure the tire bead you're working on is pushed as close to the middle of the rim channel as you can get it. * The thinner the rim tape, the easier it is to mount the tire. If you have thick rim tape, consider replacing it. Some tire/rim combinations are just too tight a fit, and you may need to use a tool. The best tool for this is the "Kool Stop bead jack" because this tool lifts the edge of the tire without going inside of it, so it is less likely to damage the inner tube than a conventional tire lever is. === ===
Put one side (one bead) of the tire on the rim with the other side open. First put the valve stem through the hole in the rim. I put the cap on the stem so it doesn't come out while I am working with it. Tuck the tube into the tire all around. Then, making sure you don't pinch the tube, work the tire into the rim, starting at one point and working around the rim with both hands. You may need a tool to pry the last part of the tire all way in. Do not use a tool with a sharp point or corner on it like a screwdriver because it could puncture the tube. I use the rounded handle on a pair of pliers but bike shops sell tools made just for this, (tire irons). When the tire is all the way on the rim, make sure that the valve is straight in the hole. If it comes through at an angle then the edge of the metal around the valve hole could cut the rubber on the valve stem and cause a leak. Make sure the valve points directly toward the hub, not off at an angle. Fill the tube partially with air. Then looking carefully at the tire where the bead sits in the rim, make sure that it is even all the way around. There is a very small ridge of rubber right there next to the rim. Make sure this ridge is an even distance from the rim all the way around on both sides of the tire. I like to wet the bead with soapy water on a rag so that it will slip into place easily. If the tire is not on the rim evenly then you will feel a thump, thump, thump every time the wheel goes around when you are riding. Fill the tire up to normal pressure. Put the wheel back on the bike and ride.
Use something called tire irons(or tire levers) to pry one side of the tire away from the rim, then you can pop the tube out. When installing the new tube, take care not to pinch it. Best if you can force the tire back on w/o resorting to tools.

Answer 2

1. Take wheel off bike
2. Wrench one side of tire over the lip of the rim, be careful not to pinch the tube
3. Pull tube away from wheel and tire
4. Locate leak. Easiest done by inflating tube, then sticking it in water. Where it bubbles there's the hole.
5. Check tire for any remaining debris. You don't want it to flat again.
6. Sand down area in a 1" radius around hole
7. Spread vulcanizing solution around hole, to a size slightly larger than your repair patch. Wait for vulcanizing solution to become almost dry.
8. Apply patch, let cure a while
9. Reinsert tube into tire
10. Wrangle tire back over lip of rim, be careful not to damage tube.
11. Put wheel back on bike,
12. Inflate, and go ride your bike.

Answer 4

Usually it's not the tire that you patch, but the tube that's inside the tire. Head over to www.bicycletutor.com and I'm sure there's video link there on how it's done.

Answer 5

Inner tubes don't really need much maintenance. Keep them inflated, keep dirt out of the valves. When you get a puncture, either repair or replace the tube.

Answer 6

You take the rim and tire off the bike, remove the tire and tube, then repair and replace on the rim.
