Tyre Pollution Explained: Hidden Environmental Impact

When it comes to pollution and the environmental concerns linked to driving, it’s not just the vehicle engine and release of carbon emissions that we need to be concerned about. As one of the most crucial components of any vehicle, tyres come with their own collection of environmental issues - starting with the production process and extending into regular use and road wear.

In this blog, we’re sharing some of the main issues and concerns around tyre pollution and the impact of tyres on the environment - starting with production and sourcing.

Tyre Production and its Environmental Impact

You need only browse our diverse and extensive collection of available tyres, from a wide array of brands, to see that tyre production is big business. Millions of new tyres are produced every year - and that means millions of tyres are also discarded every year.

While the industry is taking steps towards becoming more sustainable both in its raw material sourcing and tyre recycling schemes, the reality is that producing tyres creates byproducts that can cause harm to the environment.

What’s more, when tyres are discarded or no longer in use on the road, they are complex and difficult to dispose of. Some of the best uses include cutting tyres down into tiny particles to create rubber playground and pitch surfaces and using tyres as they are for outdoor structures in gardens and on farms. But even these uses do not avoid the pollutants that rubber is constantly releasing into our environment - unseen but causing untold damage. Which is where the connection between tyres, tyre wear, and the release of microplastics comes into play.

The Pollutant Link Between Tyres and Microplastics

The conversation around microplastics and their presence in our world seems to be growing and becoming more prolific by the day. However, when linked to tyres, they fall under a different name - Tyre Wear Particles (or TWPs for short).

These TWPs are, believe it or not, released by tyres as they drive. They are shed in such tiny particles that you don’t see them, but they exist in our air and are polluting both our bodies and our natural world.

The impact of these particles can be huge, with some of the following reported results from the release of TWPs:

  • TWPs are breathed in by those who live close to densely populated areas with high traffic levels
  • TWPs settle into the soil and alter its properties, including its ability to house crucial organisms and microbes
  • Around 5-10% of the plastic in our oceans derives from tyre wear and comes from these TWPs

TWPs are often noted by scientists as representing pollution sponges - that is, they soak up and hold all sorts of nasties including pesticides and harmful bacteria, re-releasing it into the environment.

Suffice to say, TWPs get everywhere - and their impact is widespread. But are they dangerous for us?

Are TWPs Dangerous for Humans?

In short, yes. TWPs can be inhaled by those who live in areas of high traffic, can be consumed through food and water systems, and can even be transferred by simple touch. This creates a chain of contact that is unavoidable - with TWPs credited as causing harm that ranges from cell damage to heart problems, digestive issues, and long term inflammation.

What Causes the Release of TWPs?

With all that said, what exactly is it that causes this release of TWPs, and are there any changes that drivers themselves can make to limit the release of microplastics?

Aggressive driving can increase the rate at which TWPs are released and generated. This includes but is not limited to sharp braking and accelerating, and taking corners sharply.

Tyres should also be maintained at the optimal and correct pressure to minimise the release of TWPs through excessive wear, and must be replaced when the tread pattern becomes worn below the minimum 1.6mm tread measurement.

These changes are small and will not eliminate TWPs, but they will reduce human exposure to them. Meanwhile, tyre brands and manufacturers themselves are consistently investing in more sustainable outputs and processes, including:

- Using eco-friendly materials like recycled rubber

- Using advanced technology that uses renewable energy and reduces waste production

- Tyres that last longer and don’t become worn as rapidly

- Tyres that are more fuel efficient - reducing the carbon emissions of vehicles themselves

All of this combined represents the work of an industry that wants to become greener. You can do your bit by keeping your tyres in optimal driving condition, by driving as smoothly and efficiently as possible, and by opting for tyres that are branded and marketed as being fuel efficient and more sustainable.
