Inner tube problem
6 min read
Asked by: Derek Tripp
How do you know if your inner tube has popped?
Quote from video: Usually. I do it by sliding my hand over the tube until I actually feel air on my hand in this case we can see a little pinhole. Right there. So once I found it I like to put my finger on it.
What causes an inner tube to pop?
The only way that the tube can physically explode is if the tube material is outside of the rim/tire and gets stretched beyond its means (when inflating your tire, do not exceed the maximum tire pressure noted on the sidewall of the tire) or pinched/sliced because it is no longer encased by a tire.
Why does my inner tube keep going flat?
One of the most common causes of a flat tire is a sharp object puncturing the inner tube. You’ve probably already thought of this and checked the inner tube for any foreign objects. But sometimes a sharp rock or piece of glass will get wedged below the rubber on the tire.
How long should inner tubes last?
An inner tube, inside a bike tire and not exposed to high levels of ozone or petroleum fumes (or UV light), can easily last 10-20 years.
What does a pinched inner tube look like?
Quote from video: But a pinch flat is when the tire compresses. So much that the tube actually gets pinched between like I said the object.
How do I check my inner tube?
Quote from video: If you check along the sidewall of your tire it'll tell you your size. So for example this my road bike tire is 700 by 32 that first number is the diameter of the tire.
Is it worth repairing an inner tube?
Overall, patching is cheaper and better for the environment than replacing your tube, so I recommend it for most situations. However, there are some flats that cannot be patched. If the hole is near the valve stem or if it is a linear tear and not a hole, you will need to swap tubes.
How much does it cost to get a new inner tube?
Common Bike Repair labor rates
Flat tire: New inner tube installed for $25, tube included; $20 if you bring us just the wheel. Inner tubes typically cost $8. Specialty tubes (extra long valves, odd sizes, thorn proof, etc.) may cost more.
How many times can you repair an inner tube?
Never patch a tube more than 3 times.
Why is my tire flat but no hole?
Flat tires aren’t always caused by a hole in the rubber. Instead, a malfunction or leak in the valve stem can be the culprit. The valve stem is the part of the tire that you unscrew when adding air. Any damage or even dirt on this small piece could cause your tire to lose air until it’s completely flat.
Why does my bike tire keep going flat with no hole?
The Invisible Leak
Sometimes, the leak in the inner tube is so tiny that it is difficult to spot it. The leak keeps letting the air leave the tire so slow that it takes days to go flat. Such an invisible leak happens when dust particles rub against the tube for long, or the tube is worn out.
Why is my bike tire flat with no hole?
Your tires go flat due to valve damage, pinched Presta valves stem, or pinch flatting because you didn’t put enough air into it when inflating in the first place. It is vital to keep your bike tires properly inflated for the best performance and safety.
How do I stop my inner tube pinching?
Quote from video: The best way to avoid this would be to put a little bit of air. Into the tube before pumping it up fully. Putting your hand around the rim itself and making sure that there's no tube that is showing.
What is a pinch puncture?
The second type are impact, pinch or snakebite punctures. These happen when you hit a sharp edge, such as a pothole, and the inner tube gets pinched on the rim causing it to puncture. These punctures are characterised by the two parallel slits in the inner tube they cause, that give them their snakebite name.
Can a pinch flat be repaired?
In some cases you will be able to repair a pinch flat using a puncture repair kit, however this can only be done if the kit contains a patch that is big enough to cover both holes. It also doesn’t remedy the issue entirely, so you will probably have to do a little extra work on your bike when you get back.
Can a feeding tube pop out?
If a tube falls out and is not noticed right away, you may not be able to get the device back in on your own. You can try by using a water-soluble lubricant, but you will likely need to contact your physician for help; you may even have to go to the ER.
How do you fix a popped tube?
Quote from video: So it just gets stuck and the way i fix this is by taking the back of a pin. And basically what you want to do is to push the broken parts back out. And slowly contract the pop tube as you go.

Why did my bike tire suddenly pop?
The most common cause of a bicycle tire blowout is wear and tear on the tire. Even the normal use of a bicycle could lead to a blowout in some circumstances. Repeatedly using a bicycle brake, for example, can heat the rims of the tire and elevate the temperature of the tire tube.
Why does my bike make a popping noise when I pedal?
These super common sounds are usually due to DIRTY or DRY bearings. You’ll often find that after riding your bike for a while or in harsh conditions these noises start to creep in. Areas to check if you’re hearing these noises would be: Crankset/ Bottom Bracket.
What does a popping tire sound like?
The most common sounds of a tire blowout include a loud pop or banging sound, a whooshing sound as the air exits the tire, and the flopping sound of the rubber hitting the road. When the tire explodes, you may feel the vehicle start to slow down suddenly and then pull sharply to one side.
