Tyre wear particles – minor problem for the industry or potential ‘tyregate’?

Tyres are increasingly the subject of discussion on particulate matter and microplastics

The UK government identifies tyres as potentially responsible for up to ten per cent of the microplastics in the world’s oceans, and some research conducted abroad suggests this proportion could be much higher. A study from the International Union for Conservation of Nature (IUCN) indicates that 28.3 per cent of all primary microplastics may come from tyre/road wear (this figure rises to 46.2 per cent when the IUCN includes both natural and synthetic rubber in its scenario), and earlier this year a marine biologist from the Alfred Wegener Institute for Polar and Marine Research singled out tyres as a “major influence” upon the presence of microplastics in our oceans. Taking such research at face value, it is feasible that the ‘dieselgate’ scandal could be followed at some stage by ‘tyregate’. Yet the tyre industry asserts that tyre/road wear isn’t the environmental and health risk some claim it to be. Continental’s Nikolai Setzer recently discussed this side of the argument.
