The air filled(pneumatic) tire.
The first verifiable claim for the inventor of the bicycle is Baron Karl von Drais, a civil servant in Germany. His invention was called Laufmaschine, which is German for 'running machine'.
George Dunlop was born July 19, 1888, in Meriden, CT, USA.
John Boyd Dunlop was a Scottish veterinarian and the recognized inventor of the first practical pneumatic or inflatable tyre/tire. His patent was for a bicycle tire, granted in 1888. However, Robert William Thomson invented the actual first vulcanised rubber pneumatic tire. Thomson patented his pneumatic tire in 1845, his invention worked well but was to costly to catch on. Dunlop's tire patented in 1888 did, and so he received the most recognition.
Apart from the earliest bicycle-like objects, which had wooden wheels, maybe even with steel rims, bicycles have always has tires. Solid ones, either rubber or even leather were used. Inflatable tires were invented by a John Dunlop.
A Scottish doctor, John Dunlop invented the first air filled rubber tire in 1888.
In 1888, a Scottish doctor John Dunlop invented and used the first pneumatic rubber tire on bicycles.
The inventor was Robert William Thomson in 1847. The first commercial tire was obtained by john Boyd Dunlop in 1888.
Mainly they've become lighter, more ergonomic to use, and more diversified.
In 1887, John Dunlop developed the first practical pneumatic tire for his son's tricycle, tested it, and patented it on December 7, 1888.
John Dunlop is best known for being the inventor of the pneumatic tyre. Born in Scotland in 1840, Dunlop was the one who developed the first practical pneumatic (inflatable) tyre, doing so in 1887. this first tyre was invented for his son's tricycle. After testing it, Dunlop applied for a patent, which was granted on 7 December 1888. Unfortunately, the patent was declared invalid since as it was determined that fellow Scotsman, Robert Thomson, has actually patented the concept first, in 1847. This was a mere formality, however, as Dunlop still managed to build the company that now bears his name as a result of developing the pneumatic tyre for commercial use.
I believe Charles McIntosh experimented with latex to make tyres somewhere in the early 1800's. (Charles Goodyear was next when he added sulphur to latex which made it stronger and more flexible.) and if you mean the pneumatic tyre, then you probably mean John B Dunlop who was seeking a way to give a softer ride from his son's bicycle. That was in 1888, though he was beaten by Robert W Thomson apparently, who patented a pneumatic rubber tyre in 1845.
Air is pumped into car tyres to cushion the wheel from the road surface. Initially, car tyres were solid rubber and relied on leaf springs to soften the jolting from the road. The first practical pneumatic tyre was made in 1888, in Belfast, by the Scot, John Boyd Dunlop.
