Brussels -- In a new survey, Bridgestone has found that 71% of motorists in Europe are driving on under-inflated tyres, wasting 2 billion litres of fuel a year, and adding 4.8 million tons of CO2 emissions
Bridgestone checked the tyre condition of 38,000 cars in 9 European countries in 2010. The
results show that 71 percent of motorists are driving on under-inflated tyres. Bridgestone calculates
that this habit is leading to the equivalent of 2 billion tons of wasted fuel worth â‚¬ 2.8 billion a year.
For the environment this means 4.8 million tons of additional and unnecessary CO2 emissions
annually - the equivalent of 1.8 g/km for every car on the road.
Analysis of these test results show that 7.5 percent of motorists are driving on seriously underinflated
tyres (at least 0.5 bar below recommended pressure) and 0.5 percent are putting their safety
at high risk by driving on severely under-inflated tyres (at least 0.75 bar below recommended
Almost 12 percent of tyres on the road are also worn down below the E.U. legal minimum of 1.6 mm
tread depth. Around 2 percent of inspected tyres are both severely worn and severely under
