Rather than perpetuate a myth, more accurately whilst Dunlop is given credit for the poduction development of the pneumatic tyre, the invention occurred some 43 years earlier and was by another Scot, R.W.Thomson for use on horse-drawn carriages not bicycles. Thomson patented the idea in both France and the USA but technology at the time prevented production in volume of the required thin rubber. Dunlops original tyre patent of 1888 was rescinded two years later in 1890 when it was proven that it was unoriginal and without improvement to the Thomson patent.
