He sold his rights to the pneumatic tyres to ...
Dunlop is credited with developing the modern pneumatic, or air-filled tire. The solid rubber tire was developed soon after American Charles Goodyear, who, quite by accident, discovered vulcanization in 1839, a way of combining rubber, sulfur and heat to create a rubbery substance that was flexible yet would hold its shape in hot or cold weather.

In 1845 Thomson acquired a patent for a pneumatic tire—actually a hollow leather tire enclosing a rubberized fabric tube filled with air. Although a set of Thomson’s “aerial wheels” ran for 1,200 miles (roughly 2,000 km) on an English brougham , rubber for the inner tubes was so expensive that the tires could not be made profitably, and, thus, for almost half a century, air-filled ...
