putketon

Putketon is a Finnish term that translates to "tubeless" in English. It most commonly refers to tubeless tires, a type of tire designed to be used without an inner tube. In the context of bicycles and automobiles, tubeless systems offer several advantages over traditional tubed tires.

One of the primary benefits of tubeless tires is their ability to run at lower pressures without the risk of pinch flats, which occur when the inner tube is compressed between the rim and an external object. This allows for improved traction, comfort, and handling, especially on rough terrain. Additionally, tubeless setups are generally lighter than their tubed counterparts, as they eliminate the weight of the inner tube.

Another significant advantage is the use of a liquid sealant inside the tire. This sealant can automatically repair small punctures from thorns or sharp debris, reducing the likelihood of a complete deflation and the need for roadside repairs. This self-sealing capability is a major reason for their popularity in mountain biking and cyclocross.

The transition to tubeless technology has been gradual, with initial adoption in high-performance cycling disciplines. Modern tubeless systems, however, are becoming increasingly common across various vehicle types due to their performance and convenience benefits. Installation and maintenance of tubeless tires can sometimes require specific tools and techniques compared to traditional tubed tires.
