63% of the European Motorists Drive on Under-Inflated Tyres image

A survey made by Bridgestone in 2011 on 46,000 cars from 11 European countries, show that 63% of drivers are travelling on low pressure tires.

The company said that driving with low pressure tires causes a waste of 3.1 billion liters annually, which translates in 5 billion euros, and 7.4 million tons of CO2 a year, the equivalent of an additional 2.7 g/km for every car on the European roads.

“As in previous years, the results indicate that a majority of drivers are unaware of the cost and environmental damage of failing to take care of their tyres” says Tom Fukuda, Senior Vice-President, Sales and Marketing, Bridgestone Europe.

The results of the study also show that 17.5% of motorists are driving on seriously under-inflated tyres (at least 0.5 bar below recommended pressure) and 4.3% are putting their safety at high risk by driving on severely under-inflated tyres (at least 0.75 bar below recommended pressure).

Besides this, around 20% of tyres should be replaced, being worn down under the minimum of 1.6 mm tread depth, representing an immediate safety risk to drivers of the vehicle, passengers and other road users. Almost 3.5% of inspected tyres are both severely worn and severely under inflated, exposing the driver to double danger.
