rubber was a novel product with few practical uses, thanks, largely, to its properties changing drastically with the environment. John Dunlop the inventor that started it ad invented the rubber that was used. And Goodyear is the one that made it go farther.
It was useful because it made traveling easier and made the tires stronger for more distance and carry more weight. It can be used for a lot of working machines and things that will make your job easier and not as hard.
