The tube which I had been throwing away has revived. Expensive special-sized tubes are used for machines that continue to be used for decades, such as industrial machinery. It is perfect for such cases. I was not worried about the actual repair work. I am using it for the front tire of agricultural tractor, but there is no reduction of air at all.
