Pneumatic Tire Changer

The first practical pneumatic tire was made by John Boyd Dunlop while working as a veterinarian in May Street, Belfast, Ireland in 1887 for his son's bicycle, in an effort to prevent the headaches his son had while riding on rough roads (Dunlop's patent was later declared invalid because of prior art by fellow Scot Robert William Thomson). Dunlop is credited with "realizing rubber could withstand the wear and tear of being a tire while retaining its resilience". The development of this technology hinges on myriad engineering advances. In terms of materials, the vulcanization of natural rubber is credited to Charles Goodyear and Robert William Thomson. Synthetic rubbers were invented in the laboratories of Bayer in the 1920s. Today, over 1 billion tires are produced annually in over 400 tire factories, see List of Tire Companies.

Pneumatic tires are manufactured in about 450 tire factories around the world. Over one billion tires are manufactured annually, making the tire industry a major consumer of natural rubber. In 2015 alone, 1.72 billion tires are expected to be sold globally. The production starts with bulk raw materials such as rubber, carbon black, and chemicals and produces numerous specialized components that are assembled and cured. Many kinds of rubber are used, the most common being styrene-butadiene copolymer. This article describes the components assembled to make a tire, the various materials used, the manufacturing processes and machinery, and the overall business model. Styrene-butadiene copolymer is the most popular material used in the production of rubber tires. In 2004, $80 billion of tires were sold worldwide, in 2010 it was $140 billion.

John Boyd Dunlop Invented

John Boyd Dunlop was a Scottish inventor. He was one of the founders of the rubber company that bore his name, Dunlop Pneumatic Tyre Company. He was born on a farm in Dreghorn, North Ayrshire, and studied to be a veterinary surgeon at the Dick Vet, University of Edinburgh, a profession he pursued for nearly ten years at home, moving to Downpatrick, Ireland, in 1867. He established Downe Veterinary Clinic in Downpatrick with his brother James Dunlop before moving to a practice in 38-42 May Street, Belfast. He was a good friend of Queen Victoria.

In 1887, he developed the first practical pneumatic or inflatable tyre for his son's tricycle, tested it in Cherryvale sports ground, South Belfast, and patented it on 7 December 1888.

JOHN BOYD DUNLOP

Willie Hume demonstrated the supremacy of Dunlop's newly invented pneumatic tyres in 1889, winning the tyre's first ever races in Ireland and then England. The captain of the 'Belfast Cruisers Cycling Club', he became the first member of the public to purchase a bicycle fitted with pneumatic tyres, so Dunlop suggested he should use them in a race. On 18 May 1889 Hume won all four cycling events at the Queen's College Sports in Belfast, and a short while later in Liverpool, won all but one of the cycling events.

JOHN BOYD DUNLOP

Two years after he was granted the patent Dunlop was officially informed that it was invalid as Scottish inventor Robert William Thomson (1822–1873), had patented the idea in France in 1846 and in the US in 1847. Dunlop's patent was later declared invalid on the basis of Thomson's prior art, see Tyres. Dunlop’s development of the pneumatic tyre arrived at a crucial time in the development of road transport. Commercial production began in late 1890 in Belfast. Dunlop assigned his patent to William Harvey Du Cros, in return for 1,500 shares in the resultant company and in the end did not make any great fortune by his invention. Dunlop died in Dublin, and is buried in Deans Grange Cemetery.

Aprilia rsv4 Factory Price

The Aprilia RSV4 Factory is a new bike with its own plan for success. It is powered by a 1000cc V-four engine developing 180 horsepower and 115 Nm, while weighing in at 394.6 lbs dry. We do thrust Italians when it comes to engine performance and weight reduction although style is what makes their rides stand out immediately and the RSV4 Factory makes no exception. So this is pretty much an exotic superbike with the performance to match its looks.

Troy Bayliss Ducati

Troy Bayliss Ducati

Troy Bayliss is a truly likeable character who has taken the world by storm. After replacing the injured Fogarty at the start of the 2000 season, Bayliss has emerged as one of the most dominant riders the championship has ever seen. His consistent riding style makes him a threat to be a title contender for years to come. Dont think for a minute the Aussie is boring though - his tire shredding corner exits have graced many a photo gallery since his arrival and his bold post race celebrations have elevated his fan favorite status off the charts.

Troy Bayliss Ducati

After a couple dismal seasons in MotoGP, Bayliss returned to his roots with the Factory Ducati squad in World Superbike. All he did there was storm his way onto the 2006 WSB Championship. Then for good measure he claimed a flag-to-flag victory in the MotoGP finale, where Ducati let him ride the second GP7 seat vacated by an injured Sete Gibernau.

2007 was less kind to Bayliss, will a nasty crash during actually grinding off part of the Aussies' pinkie. The tough champ still labored on with his Xerox Ducati, but had to settle for fourth championship.

Troy Bayliss Ducati

Coming into 2008,with the new 1198cc 1098R at his disposal, the Aussie earned Ducati its first win with the new machine at the opening round in Qatar. He continued his domination of the '08 season finishing on the podium 19 times, qualifying for eight superpoles and winning 11 races. Bayliss took home his third World Superbike Championship and retired from motorcycle racing.
