Airless tires, non-pneumatic tires (NPT), or flat-free tires are tires that are not supported by air pressure. The main advantage of airless tires is that they do not go flat.
Other advantages are that airless tires need to be replaced less frequently, resulting in savings. Heavy equipment outfitted with airless tires will be able to carry more weight and engage in more rugged activities.I bet you’ve seen some of that videos with tubeless/airless tyre demonstration. How about to build one with your hands ?
Cheap and simple, Using onle pvc pipes, bolts nut ands to fit all together. This construction still needs to be modified. But in general, it’s fully working concept.
In his video youtuber The Q shows you all the ins and outs of building this set of puncture-proof airless bike tires, at the end of the video, he rides his bike again, proving the success of his project.The elastic material of the pvc pipes ensures a light flow and comfort./The Q
