Driving out bad tyres
Swedish communities, the EU rubber industry association and local authorities in the Gteborg region of the country have come together to ask for greater use of 'winter' car tyres by the public in order to reduce the release of polyaromatic hydrocarbons (PAHs), which are carcinogenic, into the environment. Aromatic oils make up for about 20 per cent of a tyre and help improve the tyre's grip among other things. But they are lost into the environment when the tyres wear down. The coalition has brought out a list of brands of tyres that contains pah s within limits permitted by the EU standards (Automotive Environment Analyst , Issue 72, January 2001).
