The evolution of tyres.

Hello there!
I started something new: all kinds of Cars and minds. All kinds of car-related content. It's called 'Cars and minds, all kinds'.
This time I stumbled upon two articles about the evolution of tyres. A recent one which is about airless tyres and an old one, which is about non solid rubber tyres.
For me an interesting topic and I hope for you too.
Greetings, Gerard
