The very first Bridgestone tyre was produced on April 9, 1930, by the Japanese "Tabi" Socks Tyre Division (actually made jika-tabi). One year later on March 1, 1931, the founder, Shojiro Ishibashi, made the "Tabi" Socks Tyre Division independent and established the Bridgestone Tire Co., Ltd. in the city of Kurume, Fukuoka Prefecture. "Bridgestone" was named after the name of the founder, Shojiro Ishibashi (Ishi = Stone,Bashi = Bridge). For 2009, 2010 and 2011, a 'spec' tyre supplier, Bridgestone, was appointed by the FIM (Michelin no longer supplying any tyres to MotoGP). For the whole season Bridgestone provided 4 different specifications of front tyre, 6 of rear, and a single wet specification—no qualifying specification. For each round, Bridgestone provided only 2 specifications for front and rear. Tyres will be assigned to riders randomly to assure impartiality. Jorge Lorenzo has publicly supported the mono tyre rule.
