Tires are rubber coverings that fit around the wheels of vehicles, providing traction and support. They come in various types, such as all-season, winter, and performance, each designed for specific driving conditions. Tires are essential for safety, handling, and fuel efficiency. Tubes are inflatable rubber or plastic liners placed inside some tires, particularly bicycle and motorcycle tires. They hold air pressure, which helps maintain the tire's shape and provides cushioning. While many modern tires are tubeless, tubes are still commonly used in certain applications for ease of repair and replacement.
