How do you change the inner tube on a bike?
- Remove the tire from the rim. Place the tire lever between the rim and the tire and pry the edge of the tube from the rim. Insert the second tire lever about two spokes over and pry more edge of the tire from the rim. Continue this until you can easily pull the inner tube out from the tire.

How much air should I put in my road bike tires?
A typical road tire should be inflated to something between 90 and 120 PSI. Mountain bike tires, on the other hand, tend to run at much lower PSI.
How do you air up a Presta?
How Do You Inflate a Presta Valve without an Adapter?
- Remove the valve cap. Find the place on the valve cap where it gets smaller.
- Unscrew the valve on the tire.
- Place the modified cap upside down on the tire and screw it down a few twists.
- Attach the pump and inflate.
At what PSI will a tire explode?
Under hot weather and highway conditions, the temperature of the air inside the tire rises about 50 degrees. That increases the pressure inside the tire about 5 psi. The burst pressure of a tire is about 200 psi.
Is 40 psi too high for tires?
Normal tire pressure is usually between 32~40 psi(pounds per square inch) when they are cold. So make sure you check your tire pressure after a long stay and usually, you can do it in the early morning.
What is Presta valve adapter?
The adapter installs onto your Presta valve stem and converts it to a standard valve stem, allowing you to use your VIAIR compressor to inflate the tire to your desired pressure. In the cycling world, bicycle tire pressures vary depending on the activity.
Which is better Presta or Schrader valve?
Presta valves are easier to pump than Schrader, because they have no valve spring to overcome. In narrow rims, clincher tires also leave insufficient space between tire beads for larger Schrader valves. In contrast Schrader valves are more robust, universally used, and have an easily removable core.
How do you pump up a bike tire without losing air?
stop air leak when disconnecting inflator from presta valve
- You should not have air escaping after the chuck is removed but before the knob is screwed down.
- The trick is to pull slightly on the core as you screw it down, keeping tension on the valve will keep it closed until you have screwed it all the way in.
How do I put air in my bike tire without a pump?
These small cylinders take up little room in your seat bag and most have enough air in them to fill both your tires. Learning to use a CO2 cartridge takes only a few moments. If you don’t have a cartridge or a pump, you can get some air into a tire by blowing it up like a balloon with your mouth.
Can you inflate Presta valve without adapter?
They use an internal spring to allow inflation while keeping the valve closed. You can inflate this style easily with any regular air pump. Presta valves are a lot narrower and are commonly found on higher end bikes with narrow rims. To inflate a Presta valve you’ll need a regular air pump and a special adapter.
