Pirelli has published its Pirelli Calendar since 1964, which has featured the contribution of famous photographers over the years. The 2013 edition was commissioned to war photographer Steve McCurry. Pirelli's headquarters are located in Milan's Bicocca district, an area that is home to the rapidly growing Italian University, Università degli studi di Milano-Bicocca, and cultural locations such as the Teatro degli Arcimboldi and Hangar Bicocca, an exhibition centre for contemporary art that Pirelli founded. ==History== Founded in Milan in 1872 by Giovanni Battista Pirelli, the company initially specialised in rubber and derivative processes and also made scuba diving rebreathers. Thereafter, Pirelli's activities were primarily focused on the production of tyres and cables (for energy and telecommunications). In 2005, Pirelli sold its cable division to Goldman Sachs, which changed the new group's name to Prysmian. In the 1950s, Alberto Pirelli commissioned the building of a famous Milanese skyscraper in the same area that housed the very first Pirelli factory during the 19th century: see Pirelli Tower.〔Skyscrapers, Antonino Terranova, White Star Publishers, 2003 (ISBN 8880952307)〕 In 1974, Pirelli invented the "wide radial tyre", upon a request from the Lancia rally racing team for a tyre strong enough to withstand the power of the new Lancia Stratos. At that time, racing tyres were either slick tyres made with the cross ply technique (very wide tyres with a reduced sidewall height), or radial tyres, which were too narrow to withstand the Stratos' power and did not provide enough grip. Both were unusable for the Lancia Stratos, as the radials were destroyed within 10 km, and the slicks too stiff. Lancia asked Pirelli for a solution, and in 1975 Pirelli created a wide tyre with a reduced sidewall height like a slick, but with a radial structure. Subsequently, Porsche started using the same tyres with the award-winning Porsche 911 Turbo. In 1988, Pirelli acquired the Armstrong Rubber Company, which was headquartered in New Haven, Connecticut, for $190 million.〔(【引用サイトリンク】title=Armstrong Finds a Niche in the Tire Market )〕 In 2002 the company started a range of Pirelli branded clothing, watches and eyewear.〔 (official website )〕 In March 2015, it was announced that Pirelli shareholders has accepted a €7.1 billion bid from ChemChina for the world's fifth-largest tyre maker. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pirelli」の詳細全文を読む スポンサード リンク
