The Tyre Trepidation: A Consumer Responsibility

Transport is a continuously growing area of the economy, and one that has large environmental impacts.

Now, you may think that this is an unimportant and - let’s face it – boring subject to blog about, however tyres have been identified as a neglected ‘source of pollution’. Yes, these rubber doughnuts pose a rather serious ‘ecological threat’ throughout their lifecycle (Constantinescu, 2012).


Tyres are considered “an environmental nightmare” when they reach disposal age, at ‘risk of catching fire or breaking down, leaching toxic chemicals and heavy metals into soil structures and water tables’ (Norsa, 2015). However, a tyre’s environmental impact varies throughout its transition from raw materials to waste.

First, I invite you to observe the pressing issue of tropical forest clearance for rubber plantations which has captivated the concern of many conservationists. Briggs (2015) outlines that the tyre industry ‘consumes 70% of all natural rubber grown’ and is largely to blame for drastic land-use switches, causing negative impacts on soil and water, the significant LOSS of tropical biodiversity and putting endangered species at a greater risk of extinction.


Forest Conversion for Rubber Plantation in Northern Laos

It is predicted that an additional 8.5 million hectares of rubber plantation will be required to meet growing rubber demands by 2024.

That’s practically the size of Austria.

Yes, a space the size of a country will need to be cleared and converted, a scary reality which I wholeheartedly disagree with.

However, aside from forest and biodiversity loss, the largest environmental effect of the tyre occurs when it’s in use.




Now, tell me if I’m wrong, but when thinking about the environmental impacts of cars, driving style isn’t typically what springs to mind. However, a ‘driver's driving style is the most important factor influencing the environmental impact of tyres’ and generates the ‘largest share of emissions’ (Constantinescu, 2012)

Shocked? Me too.

Studies have concluded that ‘the most important part of tyre management and most effective means of reducing environmental impact’ is the responsible behaviour of drivers, the consumer, the national citizen, us (Constantinescu, 2012).


So how do we go about encouraging wider society to adopt what Constantinescu (2012) calls “economic driving”?

Well, as a society largely driven by wealth and consumption, it makes sense that economic incentives are deployed, right? Put simply by Treadfirst (2014): ‘Care for your car and it will save you money!”.

Simple tips which save you money and are easy to follow are publicly advertised, leaving consumers with no excuse:
  •  Travel lighter – declutter your car to reduce weight and drag
  • Open your window – spare use of air conditioning
  • Reduce your speed – rapid acceleration and sharp breaking wastes fuel
  • Make new friends – share your commute and slash your costs

However, it is inherently difficult to change behaviours and practices that are ingrained into societal daily routines.

The future fate of effective tyre management to relieve damage to the environment is ultimately left in the hands of wider society and their willingness to change their driving habits.

So tell me, will you?

  1. Hi Caitlin! I am amazed by the fact that an area as large as Australia would be needed for rubber plantations! I will definitely take into account the tips given to reduce the amount of tires ruined :) I was wondering, do you know to what extent tires can be recycled? In terms of re-use have you considered up-cycling? (check out the picture of tire-plant-pots! https://s-media-cache-ak0.pinimg.com/736x/5d/f8/f7/5df8f732a3b0ca4ea4efa7fdc6644e98.jpg )

    Look forward to your next blog-post!

    1. Hi Maria, I know that shocked me too! I know that tyres can be up-cycled - love the plant pots -and also the rubber can be made into sleeping mats, soft flooring like you find outside nursery schools etc. As for tyre recycling at home, it usually occurs when taking your car into a garage, they'll recycle old tyres for you. However old tyres cannot be remade into new tyres as their flexibility worsens and their drag increases due to over use and age so recycling doesn't detract from the need to produce new tyres. Thank you for your comment!

    2. Thanks for that Caitlin! I totally agree that it is hard to re-make tyres! But I am glad they are used in other ways!

  2. Really interesting post, and as Maria said, quite shocking when you see those kind of statistics. Are there any viable alternatives to using rubber for tires in order to make them more environmentally friendly?

    1. Hi Ben, thank you for your comment!
      There are various ways that tyres are being made more sustainable such as design to decrease rolling resistance and thus fuel consumption. However in terms of their actual manufacturing and changing the raw material used check out this New York Times Post - http://www.nytimes.com/2010/06/20/automobiles/20TIRE.html?_r=0 . Basically, tyre manufacturers are testing out and implementing various alternative materials to replace black-carbon to decrease rolling resistance and friction - they've even tried using orange peel oil! Researchers are also attempting to revert production back to the renewable source of latex sap from rubber trees and away from adding crude oil. But, in terms of reducing the environmental disruption from deforestation for rubber plantations it's more tricky as rubber is required to make tyres. There's been talk about moving from the tropics for natural rubber - stopping deforestation of crucial tropical forests - and to desert shrubs with the potential to produce latex (check out this post > http://www.scientificamerican.com/article/alternative-source-of-tire-rubber-gains-traction/).
      Hope this answers your question?
      Thanks again Ben!
