Ford has commended supplier Continental Tyre North America's decision to voluntarily recall P275/60R17 tyres used on 106,701 2000-model and certain two-wheel-drive 2001-model Expedition and Navigator SUVs. Four-wheel-drive vehicles are not affected. Continental yesterday announced a recall of 595,000 of its P275/60R17 ContiTrac AW and General Grabber AW P275/60R17 tyres which will be replaced free of charge because they are not up to standard after two years' service.
