Experienced cyclists know punctures occur frequently, so it’s important to learn how to change a bike tire even if you are a more casual cyclist. When your bike tire is punctured, you may be able to repair it yourself. But if the damage is too extensive, or the tire is already severely worn, then replacing the tire may be necessary.
Typically, bike owners cannot repair large breaks, splits, or punctures with a tire patch kit. Similarly, any significant signs of tire wear, strain, or cracks should indicate it’s time to replace a bike tire. Most cyclists learn how to fix a bike tire to deal with minor punctures and replace one after more severe damage has occurred. If you need a refresher, are new to cycling, or are getting into bike maintenance, then follow the steps below to learn how to change a bicycle tire.
Tools & MaterialsTo access the bike tire, either put the bike on its side or stand it upside down, resting on the handlebars. However, some cyclists avoid placing the bicycle upside down because this position could damage the handlebars or seat. Choose the position with which you feel the most comfortable. Another option is to invest in an upright bike stand that can position the bicycle off the ground while you work. If you are laying the bike on its side, make sure the chain side faces up.
If you are replacing the back tire, then it’s important to adjust the gears to the smallest ring beforehand to make it easier to remove the tire. The smallest ring is the outer gear of the bike.
If the bike includes a quick-release lever, it will be located in the center of the bicycle wheel. Loosen and remove the lever by pulling up and turning the lever 180 degrees. Then set it aside for reinstallation. This should free the wheel to allow the damaged tire to be replaced. However, many bikes don’t come with a quick-release lever. If this is the case, then a wrench is needed to loosen the nut in the center of the wheel.
Typically, a 15 millimeter wrench will be the correct size to loosen and remove the wheel nut. Keep in mind that you can also check the bicycle manual or the manufacturer’s website for details on how to remove your specific bicycle tire. Additionally, if the nut is seized, WD-40 or a similar lubricant can be used to help loosen the threads and remove the nut.

If you attempt to remove the wheel without detaching the brake cables, the force can damage the cables. On some bikes, the brake cables will disconnect automatically when the quick-release lever is removed, but the brake calipers must be squeezed in order to release the cables in most cases.
Don’t forget to lift the chain off of the gears when replacing the rear wheel on a bike. Once the chain and brake cables are disconnected and the wheel nut or quick-release lever has been removed, you can lift or pull the tire out of the forked slot where it usually sits on a bicycle.
To remove the rubber tire from the metal wheel, the tire needs to be deflated completely. Take off the air valve cap and set it aside for reinstallation. Release the air from the tire with a wrench by pressing down on the plunger inside the air valve. Alternatively, your bike may have a Presta valve or a Dunlop valve; these need to be pulled up to release the air.
If the air valve has a retaining nut or lock ring securing it to the wheel’s rim, then loosen and remove the part, placing it with the air valve cap for reinstallation at a later stage in the process.
The deflated tire will still be difficult to remove from the rim of the wheel. First slide a tire lever between the rim and the tire, then use leverage to pop the edge of the tire up out of the rim. Secure the tire lever to the spokes of the wheel and use a second tire lever on another section of the tire.
Work the second tire lever around the rim of the wheel until the entire side is free. This should give you enough space to reach inside the tire and pull out the inner tube.
Once you have removed the inner tube, you should be able to take the tire off the metal wheel by rolling or twisting the tire over the edge of the rim with your hands. Work your way around the outside of the wheel until the tire is free, and inspect it for any serious damage. In many cases, only the inner tube needs replacing, but if there is severe damage to the outer tire, then it will also need to be changed.

Take the new tube out of the packaging, making sure to remove the dust cap, lock ring, and valve cover. Unfold the tube and check to make sure it has no pre-existing damage, then connect it to a bike pump or tire inflator to add air to the new tire tube. Do not fill the tube all the way just yet.
The purpose of adding air at this stage is to help the tube hold its shape and avoid damage caused by pinching, bending, or twisting the tube while reinstalling it. Put any small parts in a safe spot to make sure that they are not misplaced.

Whether installing a new tire or refitting an old tire with a new inner tube, it’s recommended to inspect the inside and outside walls of the tire for any existing damage, severe wear and tear, or sharp objects that could cause additional damage before installing the inner tube. Refit one side of the tire on the rim of the wheel, ensuring the tread is pointed in the correct direction.
Slide the air valve through the valve hole and feed the inner tube into the hollow space inside the tire and wheel rim. With the tube in place, twist the outer edge of the tire so that it slips into the wheel rim. Try to start near the valve and finish across from it—the tire will be looser in this position.
If the tire resists too much, you may need to let some air out of the inner tube or use a tire lever to help position the last section, where the tire is the tightest. Also, remember to reinstall the lock ring or valve retaining nut if your bike has one.

Use a bike pump or home air compressor to fully inflate the inner tube. If the PSI is not written on the tire, you can refer to the bicycle manual or manufacturer’s website for the appropriate air pressure. Don’t forget to put the cap back on the air valve to prevent accidental tire deflation during use.
Slide the wheel back onto the bike and secure it with the quick-release lever or wheel nut, as applicable. Reattach the brake cables and lift the chain back onto the gears if you replaced the rear tire. Rotate the wheel to ensure it spins freely, then place the bicycle upright and test the repair with a short ride.
Make sure to clean up any old parts and dispose of old tires through local recycling facilities. Some bike and car shops also have programs for accepting old tubes and bike tires.

Regular bicycle maintenance and proper storage can help keep a bike in top condition over years of ownership. Always replace or repair any tire damage as soon as possible to avoid bending a bike’s wheel. Also, during the repair or replacement process, make sure to keep track of all small parts, like nuts, lock rings, or valve caps. While small in size, their purpose is essential to the bicycle’s function, and losing one during a repair can create another problem needing to be resolved before the bike can be used again.

Follow these simple steps for replacing a punctured bicycle tube.
You can even fix the flat on the go if you have a spare tube, tire levers and a pump.
By the DIY experts of The Family Handyman Magazine
Step 1: Remove the tire and old tubePry under the bead of the tire with one of the tire levers and hook it to a spoke. Move over about 4 to 6 in. and insert the other tire lever. Pry it down and then slide it along the rim to release the tire.
The first step of how to change a bike tire is to release the brake and loosen the axle nut so you can remove the wheel from the bike. Most bikes have a quick-release mechanism on the brake and a quick-release lever on the axle. If you’re not sure how to remove the wheels on your bike, check the manual or visit your local bike store and ask someone on staff to show you how. Do this before you have a flat so you’ll be prepared. For a guaranteed trouble-free fix, buy a new tube rather than patching the old one (see “Valve Types” below).
After removing the wheel from the bike, the next step is to take one edge, or bead, of the tire off the rim so you can remove the damaged tube (Photo 1).
Pull out the tube. Then remove the tire completely from the rim, put it around your neck like a necklace and turn it inside out while running your fingers along the inside to feel for sharp objects. Be careful, though—there could be bits of glass lodged in the tire.
If you don’t want to walk home after having a flat, here’s a tip: Assemble a tire repair kit like this. A repair kit is one of the most valued bicycle accessories you’ll want. You can put it in a resealable plastic bag and tuck it in a knapsack or buy a small pack that straps under your bicycle seat. Not including the seat pack, the kit cost us about $38.
Step 2: Install the new bike tubePartially inflate the new or patched tube and insert the valve stem into the hole in the rim. Then work the tube into the tire.
Press the bike tire back over the rim, being careful not to pinch the tube.
If it’s too tight to push the last section by hand, use the tire levers to pry the bike tire onto the bike rim.
After checking the tire, put one bead back on the rim, leaving the other side loose so you can install the new (or patched) tube (Photo 2).
Photo 3 shows how to push the second tire bead back onto the rim after the tube is in place. When the tire is completely installed, check all around on both sides to make sure the tube isn’t pinched between the tire and rim. To do this, push against the bead and look into the space between the tire and rim to be sure it’s clear.
Now you’re ready to fully inflate the tire. But there’s one last thing to watch for. Occasionally the bead may not seat properly on the rim, so stop before the tire is inflated to full pressure and rotate the wheel while you inspect the area where the tire and rim meet. If you see a spot where the bead isn’t seated in the rim, let a little air out and work the bead into the rim with your fingers.
Then inflate the tire to the pressure listed on the side. Reinstall the wheel and spin it to make sure it’s centered between the brakes and rotates freely. If you’ve done an emergency repair using the CO2 cartridge, you may not have enough pressure. When you get home or to a bike store or gas station, fill the tire.
When you go to buy a new tube, take the old tube with you and match the valve. Presta valves have a nut on a threaded shaft that seals the air in and must be loosened to inflate the tube. You need a pump that’s compatible with a Presta valve to inflate these tubes. If you have Presta valves on your bike, keep a Presta-to-Schrader adapter with you so you can use a gas-station air pump to inflate your tire.

If you are a cyclist, you need to be able to deal with a number of common problems that can happen on the road. A punctured wheel is one of the main ones. Unfortunately, you can run into a nail, a piece of metal or a broken bottle almost anywhere, and sooner or later it happens to everyone. Already happened? Read our review, which we prepared together with Onliner, on how to change or seal the tube, tire on a bicycle.
To remove the damaged tube from the wheel, you need to remove it from the bike - this is much more convenient to work with. Then follow the step by step instructions:
1.
Unscrew the protective cap from the nipple. If necessary, completely deflate the wheel. This will make the job easier, as there will be no unnecessary resistance.
2. Using a pry bar, hook the edge of the tire and pull it out of the rim. Special tools allow you to carry out this procedure quickly and as painlessly as possible. If there is no pry bar, you can try using any thin and durable object, such as a spoon. Her handle has repeatedly rescued cyclists who did not have repair tools at hand. Just make sure she doesn't bend over.
Important: The tool should not have sharp ends, so a screwdriver is not the best solution, although it fits the given shape. With it, you can only damage the wheel more. If you want to keep the tire, don't.
3. It is optimal to use two mounts. First, pick up the edge of one, then, when you fix the position, in 2-3 centimeters, pick up the tire with the second mount. This will be followed by a release of pressure, and the work will go easier.
While continuing to support the first mount with your hand, continue prying the tire in a circle with the second until it is completely released from the rim.
4. Now that one end of the tire is completely out, release the nipple and remove the damaged tube.
We will consider the installation process with the installation of both a new camera and a tire. If you are keeping the old camera, skip the first step.
1. We put a new tire on one “rib” of the wheel, so that we have a free pocket for inserting the camera.
2. We take a new chamber (deflated) and, starting from the nipple, lay it along the rim.
3. While the camera is not yet closed, pump it up a little to make sure that it is laid flat and not twisted anywhere. If the tube is installed with a kink or twisted during installation, it will most likely burst as soon as you get on the bike. Agree, you don’t need such unnecessary frustrations, because these are not only ruined plans, but also additional financial costs.
4. Now you need to "fill" the tire into the rim. In the first steps, this is done manually, but at the end, installation will again be required. You can do it with one, but it's better to use two. Use it to pull the tire towards you a little so that it easily enters the rim. You can push the tire a little inward with a mount so that it is better fixed. The main thing is that the attachment depth is the same throughout the circle.
5. After the wheel is closed, pump up the chamber to the desired state. Usually the right pressure is indicated on the tire, check it to properly set your pump.
6. Now screw the cap on the nipple to fix the condition of the wheel.
7. It remains to install the wheel in place and that's it. Now your bike is back on track! Make a small circle on it at low speed to make sure everything is secured properly and you feel comfortable. If necessary, pump up the chamber of the second wheel so that they are equally elastic.
After replacing one tube, many cyclists experience minor discomfort while riding. If everything is fine, you can go to the road. What if something happens, you already know how to change a tire and you can do it even in field conditions.
Try not to rush during the procedure and be careful at every step. Any carelessness can then turn into problems on the road. If you are saving an old tire, be sure to check the inside of it for any piercing or cutting elements. It often happens that part of the object that pierced the camera breaks off and remains in the tire. Doing so may damage the camera again. So, if you managed to find the "culprit" of the tragedy, make sure you extract it completely.
When working with the pry bar, be sure to hold it with your hand, even if it seems to you that it is holding itself. The resistance of the tire can easily push it out. In the best case, it will simply fall and you will have to start work again. At worst, it will fly out with force and can hit you in the face. The sensations are unpleasant, not to mention the fact that it can be traumatic.
Bicycle tires and inner tubes
Unfortunately, the violation of the integrity of bicycle tires and tubes is far from rare, so the topic of our article today is how to remove a tire from a bicycle wheel and put it back on. To successfully cope with this task, you need to at least superficially know the design of a bicycle tire and know the special terminology. So let's get started.
Bicycle tire includes 4 elements:
Its purpose is to securely fasten the tire to the wheel rim of the bike. The materials for its manufacture are Kevlar (most often), synthetics or steel wire. Steel beading cable - the most budgetary. The cost of Kevlar cables is much higher, they have less weight, they are easy to store when rolled up. Kevlar cable can be taken with you on a trip as a backup. It won't take up much space.
This is its carcass or foundation. This element largely determines the strength of the tire. This is a diagonal weave of nylon threads. Weave density is determined by the number of threads per 1 inch. This figure is in the range of 24-130. Naturally, the higher this figure, the better the strength qualities of the tire.
This is a rubber cover. There are two varieties.
It is used in tourist and city models of bicycles; This is the part of the tire in direct contact with the road. The performance of tires depends on the tread depth and type of pattern.
Bicycle tires are made from conventional rubber or polymeric materials. Rubber has a better grip on the surface, but in terms of wear resistance it is inferior to the compound. The cost of the compound is lower, but when driving off-road, it has proven itself better than rubber. By type, 4 main types of tread can be distinguished: slick, semi-slick, mountain, winter. Each of them behaves better in the environment for which it was created. Slick on the road, semi-slick off-road, dirt road, the winter tread has a spike for ice.
You may need to remove the bike tire in the following cases:
In this case, the tire is removed, the punctured bicycle chamber is replaced with a whole one, and then the wheel is reassembled; If desired, the tire can be removed and replaced without the use of tools (this will be discussed in detail). But, if you follow all the rules, you may find it useful:
To remove a tire from a bicycle wheel, proceed as follows:
At the same time, try, if possible, to remove the air as completely as possible so as not to touch or damage the bicycle chamber; To mount, proceed as follows:
It remains to mount the wheel and apply the brakes.
When working with a tire, do not forget that the camera is made of soft and thin material. All actions must be carried out so as not to damage the camera.
The possibility of a tube puncture always exists. The situation when you need to remove a tire can be taken by surprise, so that you do not have any tools with you. It's almost impossible to do this without tools. To replace it, you must have a spare kit if you took it and what kind of tool you still have. By default, we will assume that you still took the wheel repair kit for a bike ride. So, if you don't have montages, how can you deal with this problem?
For a comfortable ride on a bicycle, an important point is the optimal tire inflation. With insufficient inflation, the cyclist has to exert more force while riding, the bicycle tires wear out faster. Over-pumping reduces traction, makes the ride harder, and increases the risk of tube puncture.
To minimize the risk of punctures, look for tires with good side coverage when purchasing. Another indicator is cord weaving. The denser it is, the better the product. A useful device is a special anti-puncture tape located between the tire and the chamber.
Be sure to take a tire repair kit with you when you travel. This will allow you to quickly deal with the trouble.
To repair tubeless tires bikers typically use:
The most common repair tool is a cord harness. This is a nylon strip impregnated with an adhesive compound.
