What is "when you pump a bicycle tire?

When you pump a bicycle tire, you are increasing the https://www.wikiwhat.page/kavramlar/air%20pressure inside the tire. This increased air pressure provides the support needed for the bike to roll efficiently and comfortably.

Here's a breakdown of what's happening:

  • Air Compression: The pump forces air into the tire. This compresses the air molecules, increasing their density.

  • Pressure Increase: As more air is forced in, the pressure inside the tire rises. This pressure is what supports the weight of the rider and bike.

  • Tire Shape and Stiffness: The increased pressure causes the tire to inflate to its designed shape. A properly inflated tire is firm and provides good rolling resistance. Under-inflated tires are soft and create more friction. Over-inflated tires can be too rigid and uncomfortable, and more susceptible to punctures.

  • Pump Mechanisms: There are different types of pumps. Most use a piston to draw air in and then push it into the tire through a valve (typically a Schrader or Presta valve). Some pumps also have a https://www.wikiwhat.page/kavramlar/pressure%20gauge to show how much pressure has been added.
