http://tomsshoessaleonline11.tumblr.com,It’s a little scary to think how much rubber is actually in contact with the road when you’re riding your motorcycle,longchamp borse; not a lot,longchamp sale. We put our trust in the few square inches that prevent us from sliding. Today’s tyres are a magnificent feat of engineering,borse longchamp, and for that we have to thank the pioneers such as John Boyd Dunlop, Andre Michelin and Charles Goodyear,longchamp sale.
Although Goodyear,ray ban wayfarer, from New Haven Connecticut,longchamp taschen,The History of the Tyre, is credited with vulcanising rubber in 1839,longchamp taschen, the man who first invented and patented the pneumatic tyre was Robert William Thompson, the eleventh of twelve children of a Scottish woollen mill owner,lunettes de vue ray ban. After moving to Charleston USA at the age of 14,louis vuitton borse, he returned two years later and taught himself Chemistry,The History of the Tyre,longchamp outlet. He was still only 23 in 1845,ray ban pas cher, when he patented the pneumatic tyre,toms shoes. His tyre had a number of small inner tubes inside a leather casing that was bolted to the wheel. One of the great advantages of this was that the tyre still performed even after a puncture,longchamp bags. This sounds primitive now,longchamp outlet, but the alternative in those days was a steel rim strapped around a wooden wheel by a Wheelwright,longchamp 2013http://abatterybank59.tumblr.com}. The word ‘tire’ is derived from the function of this steel rim,ray ban pas cher; it was designed to tie together the wooden spokes of the wheel,ray ban carava. The American spelling of ‘tire’ was used in Britain along with ‘tyre’ to describe the outer rim of a wheel,The History of the Tyre,louis vuitton uomo, but was discarded in the 19th century, probably because some patent documents contained the latter,lunette ray ban, although ‘tire’ was still in use to describe the metal variety.
In 1888 John Boyd Dunlop invented a tyre with one inner tube, but the solid tyre was still being used extensively,The History of the Tyre,longchamp outlet. When a cycle race in Belfast was won by a bicycle with Dunlop’s pneumatic tyres, people began to sit up and take notice. One of the drawbacks of this tyre was the difficulty in removing the inner tube, and in 1890 CK Welsh invented the inextensible lip,alviero martini portafogli, which was to become the basis of modern tyre design,lunette ray ban.
In 1895 Andre and Eduard Michelin introduced the first pneumatic car tyre,longchamp outlet. The story goes that at the time that they were running a rubber factory in Clermont-Ferrand,borse alviero martini, France,ray ban wayfarer, a cyclist who was having trouble with his pneumatic tyre appeared at their premises. It took an eternity to remove the tyre which had been glued to the wheel,longchamp online shop. After it had been repaired,toms outlet, it had to be left overnight to dry,longchamp bags. The next day,longchamp handbags, the tyre failed within a few minutes, but the brothers were inspired to come up with something better.
In 1903 Goodyear patented the first tubeless tyre,http://tomsshoesoutlet56.tumblr.com, but it took until 1954 for it to reach production,longchamp outlet. Other notable advancements were the first pneumatic aircraft tyre in 1906,longchamp bags, and the introduction by Goodyear and Dunlop of pneumatic truck tyres in 1919,longchamp outlet. In 1911,longchamp outlet, Avon began to produce motorcycle tyres,alviero martini outlet. In 1946 Michelin came up with the radial tyre and in 1972,longchamp taschen, Dunlop dispensed with the inner tube altogether, although BF Goodrich had introduced the tubeless tyre in 1947. BF Goodrich also offered the radial to the USA in 1965,discount longchamp. In 1974 Pirelli introduced the wide radial tyre,toms outlet.
So the next time you’re cruising along on your bike,toms shoes,The History of the Tyre, think how much nicer it is with that few square inches of rubber,discount toms, rather than a steel band. Ride safely,louis vuitton outlet.Related articles:
