Europeans’ concern about the spiralling cost of fuel is being exacerbated by the state of motorists’ tyres according to research conducted by Bridgestone. According to the manufacturer, four billion litres – worth approximately £4.6 billion – of fuel are being wasted every year due to the under-inflated tyres of four in every five motorists. This inadequate tyre care does not just affect motorists’ wallets; the wasted fuel equates to 9.3 million tonnes of unnecessary CO2 emissions, and therefore increases the harm to the environment caused by motoring. The findings come from safety checks carried out on 52,400 cars in 15 E.U countries in 2009.
