The Firestone and Ford tire controversy was a period of unusually high tire failures on the Ford Explorer and related vehicles equipped with Firestone tires. The Ford Motor Company had a historically strong relationship with Firestone since its inception, with Henry Ford and Harvey Samuel Firestone being personal friends and even the two families being linked in marriage with their respective grandchildren, William Clay Ford, Sr. and Martha Parke Firestone being married in 1947. United States-based Firestone became a subsidiary of Japanese tire manufacturer Bridgestone in 1988. ==Problem detection== In May 2000, the U.S. National Highway Traffic Safety Administration (NHTSA) contacted Ford and Firestone about the high incidence of tire failure on Ford Explorers, Mercury Mountaineers, and Mazda Navajos fitted with Firestone tires. Ford investigated and found that several models of 15-inch Firestone tires (''ATX'', ''ATX II'', and ''Wilderness AT'') had very high failure rates, especially those made at Firestone's Decatur, Illinois plant. This was one of the leading factors to the closing of the Decatur plant.〔Velasquez "Business Ethics" (pg. 296–299)〕 Joan Claybrook, who was the president of the public advocacy group Public Citizen and previously an Administrator of the NHTSA, stated before the Transportation Subcommittee United States Senate Committee on Appropriations on September 6, 2000, that, "there was a documented coverup by Ford and Firestone of the 500 defect".〔http://www.citizen.org/autosafety/article_redirect.cfm?ID=5413〕 This refers to the 1970's debacle that had already tarnished Firestone's reputation.〔http://www.jags.org/TechInfo/2001/05May01/tires/historyoftires.htm〕 Also Clarence Ditlow; Executive Director for the Centre for Auto Safety in his statement before the Senate Committee on Commerce, Science and Transportation in Washington D.C., September 20, 2000〔(Senate Committee On Commerce, Science And Transportation, Washington D.C., September 12, 2000 ) (from the Internet Archive)〕 stated "Emerging Information shows that both Ford and Firestone had early knowledge of tread separation in Firestone Tires fitted to Ford Explorer vehicles but at no point informed the NHTSA of their findings". 〔(Bridgestone/Firestone Recall: A Case Study in Public Relations, by Dana L.
