It's important to understand the difference between a tire and an inner tube when it comes to bicycles. The tire is the outer rubber part that covers the wheel's rim. It is designed to provide optimal grip on the road and bear the weight of the cyclist. The inner tube, on the other hand, is a rubber tube located inside the tire. It is filled with air and plays a crucial role in shock absorption and bike stability.
Unlike car tires, most bicycles have removable inner tubes, which allows for their replacement in case of a puncture. Therefore, it's essential to distinguish between these two components to properly maintain your wheels and avoid breakdowns during bike rides.
