What is a wheelchair Inner Tube?

An 24 Inch (25-540) Inner Tube for a wheelchair is a flexible, inflatable rubber or latex tube that sits inside the wheelchair tire. It holds air pressure, which gives the tire its shape and provides cushioning for a smoother, more comfortable ride.

Key Functions of a 24 Inch (25-540) Inner Tube:

Maintains tire shape and pressure: It inflates to support the tire, much like in a bicycle.

Provides shock absorption: Helps absorb bumps and reduce vibrations.

Enables tire inflation/deflation: It has a valve (like Schrader or Presta) for adding or releasing air.

A 24 Inch (25-540) Inner Tube for a wheelchair is a specific size of air-filled tube designed to fit 24-inch pneumatic tires commonly used on certain manual wheelchairs, particularly those designed for active users or sports wheelchairs.
