What is a pinch flat?
This notorious type of flat tire is known as a pinch-flat or snake-bite, and it occurs when your wheel hits something with enough force that the pressure of the air in your tire is overcome and the edge of the rim slices through the tread and/or bead of the tire creating not one but two holes in your tire.
Do puncture resistant bike tires work?
Yes, puncture resistant tires work. Many riders experience fewer with puncture resistant tires. These tires work by either increases tire thickness or adding a protective layer inside the tire. Puncture resistant tubes, tapes, and sealants are also alternatives to prevent flats.
Why can’t I fill my bike tire?
Make sure you press hard enough to fully seat the pump fitting onto the valve. If that doesn’t help, your tire valve could be stuck closed, or the pump fitting (the thing you press over the tire valve) might be broken. Inside the pump that attaches to the stem is a micro bolt with a vertical line.
Are bicycle tire liners worth it?
Tire Liners Liners are popular and work well, but they do add 6 oz. or more to the weight of your tires which adds noticeably to your rolling resistance in higher performance tires. However, if you live in an area with lots of thorns or road debris, liners could be well worth the weight.
Why do my tubeless tires go flat?
Air leaks out of any tire, whether a tube is used or not. While some tubeless clincher tire/rim combinations actually hold air better than a standard tube, many lose air pressure faster than a conventional tube tire. If the tire deflates, the seal between the tire bead and rim can be lost.
Why do pinch flats happen?
Pinch flats are caused when you ride into something that causes a sharp impact — a rock, railroad track or edge of a pothole are prime culprits. The impact compresses the tire so much that the tube is pinched between it and edges of the rim.
Can you patch a pinch flat?
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.
How do I get a pinch flat?
A pinch flat is when you hit a sharp edge with your bike tire had enough that it presses and pinches your inner tube against your rim hard enough to perforate the tube and cause a flat tire. A pinch flat is distinctive because there are usually two small holes side-by-side in your inner tube in a snakebite pattern.

Why does my bicycle tire keep going flat?
Some of the most common reasons your tire will become flat include: Punctures by a sharp object. Failure or damage to the valve stem. Rubbed or ripped tire.
Why do bike tires go flat when not in use?
When not in use, tires get deflated over time. This is mainly due to the permeability of the tube and the small size of air molecules. Slowly air molecules find there way through the tube and valve seal.
Can you fill up a bike tire at a gas station?
You can purchase one from your local cycle shop. When using a gas station pump, ask the attendant for a pressure gauge and inflate your tires in small bursts, checking the pressure after each one. Gas station pumps are extremely high pressure, and you can pop your tires if you’re not careful.
How do you pump up a bike tire without losing air?
If you want to remove the bike pump without losing air, try to unscrew the head as soon as possible. Feel free to hold the valve with index finger and thumb. Put everything (hose, head, and valve) in a line to screw coupling and turn freely. Avoid exceeding the maximum pressure limit of a tire.
How do I know if I have Schrader or Presta?
The visual differences between the two are obvious, with the Presta (pictured above) being slimmer, lighter and having a lock nut to close that you can see on the top. Schrader valves are wider, more robust and have a spring mechanism on the inside to keep the valve closed, rather than a screwable top section.
