These tyres had been used mainly on Ford's Lincoln Navigator Sports Utility Vehicle. Continental has said there was no indication of any serious accidents, injuries and fatalities. It is still not clear why the tyres have had to be recalled. Some reports suggest that the tyres were involved in fewer than five accidents.
Fear centres on the fact that the tyres had shred chunks of tread.
Most of the Navigators were sold in the US, although some were sold in Saudi Arabia and other Gulf countries.
