Bridgestone's first run-flat tyre was introduced in the early 1980s with an aim to keep disabled drivers' vehicle mobile, even after complete air loss. The Porsche 959 was the first mass-produced vehicle equipped with run-flat tyres, making them standard equipment in 1987. In this early application, these tyres could not offer the smooth, comfortable ride as compared to conventional tyres.
Striving to solve this problem, Bridgestone developed a second-generation run-flat tyre in 2005 which offered improved riding comfort. And, in 2009, Bridgestone introduced new technology in the third generation run-flat tyres, which offers almost the same riding comfort as conventional tyres.
