Who invented the pneumatic tyre and when?

The most common belief is that the pneumatic tyre was invented by John Boyd Dunlop, a Scottish veterinarian. He developed the tyre in response to the discomfort his young son experienced while riding a tricycle with solid rubber tyres.

But, there was in fact a patent in 1846 by the lesser known Scottish inventor Robert William Thomson for an earlier 'pneumatic' tyre, known as Thomson’s “Aerial Wheels”. These did not catch on as well as John Boyd Dunlop’s tyres.

What year was the pneumatic tyre invented?
