Who invented the tyre?

Who invented the tyre?

Charles Goodyear invented vulcanized rubber in 1844 that was later used for tyres. In 1888, John Dunlop invented the air filled or pneumatic tyres, for bicycles. In 1895, Andre Michelin was the fires person to use pneumatic tyres on an automobile, however not successfully. In 1911, Philip Strauss invented the first successful tyre, which was a combination of tyre and air filled inner tube.

In 1903, P.W Litchfield of the Goodyear Tire Company patented the first tubeless tyre. In 1908, Frank Seiberling invented grooved tyres with improved road traction. In 1910 B. F Goodrich Company invented longer life tyres by adding carbon to the rubber. Radial tyres are now used extensively because of their excellent road grip, though they are more costly than ordinary tyres.

Pneumatic Tyre:

John Boyd Dunlop (1840-1921) was a Scottish veterinarian, and the recognized inventor of the first practical pneumatic or inflatable tyre. His patent was for a bicycle tyre, granted in 1888. However, Robert William Thomson (1822-1873) invented the first vulcanised rubber pneumatic tyre. Thomson patented his pneumatic tyre in 1845. His invention worked well, but was too costly to succeed. Dunlop’s tyre patented in 1888 did, and so he received the most recognition.
