They make tyres. You know, the stuff that goes under your car and rolls? Yes, without them we would probably be some very sore buttocks and extremely noisy cars. Thank the gods for Mr Goodyear. Just imagine how noisy our cities would be without those rubber tyres. If you read the history of the founder of vulcanized rubber, you would be kind of sad to realize inventing the vulcanized rubber didn't make Mr Goodyear rich, in fact he went into debt and was imprisoned. Now it is probably one of the most important thing since the invention of pizza. And oh, they are also famous for their Goodyear Blimp. They were also heavily involved in racing and motorsports. I mean that is what they do right - they make tyres and tyres are extremely important in racing. In 2010, their total sales amount to US$18.8 billion. That is a heck lot of tyres that they sell. Just look at the number of cars on our roads these days.
