Tubeless tires are a type of tire that does not require an inner tube to hold air. Instead, they have a sealed inner lining that allows air to stay contained within the tire itself. This design reduces the risk of punctures, as there is no inner tube that can be damaged. These tires are commonly used in bicycles, motorcycles, and automobiles due to their advantages, such as lower weight and improved performance. Additionally, if a tubeless tire does get punctured, it can often self-seal with the help of a special sealant, allowing for a safer and more convenient ride.
