Inner tubes are inflatable rubber or plastic structures used primarily in various types of recreational activities, such as tubing down rivers or water parks. They provide buoyancy and comfort, allowing users to float on water while enjoying leisure activities. Inner tubes come in various sizes and designs, catering to different age groups and preferences. In addition to water activities, inner tubes are also used in bicycles and motorcycles as part of the tire system. They help maintain air pressure, providing a smooth ride and better traction. Proper maintenance of inner tubes is essential for safety and performance in both recreational and transportation contexts.
