Pollution From Car Tyre Wear Is 1,000 Times Worse Than Exhaust Emissions





A new research believes pollution from tyre wear could be 1,000 times worse than pollution from exhaust emissions. Do you believe in the results?


Internal combustion engines are gradually being replaced by electric cars due to their heavy pollutants that cause respiratory diseases like emphysema, asthma and bronchitis.

But, according to new research from Emissions Analytics, pollution from tyre wear could be as much as 1,000 times worse than pollution from exhaust emissions.

Harmful particle matter from tyres, as well as brakes is a very serious and growing environmental problem.

These problems is being worsened by the increasing popularity of large, heavy vehicles such as SUVs.

Another factor is the growing demand for electric vehicles. EVs are heavier than standard cars because of the weight of their batteries.

Unlike exhaust emissions, which have been rapidly reduced by automakers, vehicle tyre wear pollution is completely unregulated.


Non-exhaust emissions (NEE) are particles released into the air from brake wear; tyre wear; road surface wear and resuspension of road dust during on-road vehicle usage.

No legislation is in place to limit or reduce NEE. But these pollutants cause a great deal of concern for air quality.

Measurements found that 5.8 grams per kilometre of harmful particles are emitted by tyres as they wear when a car is being driven.

Compared with regulated exhaust emission limits of 4.5 milligrams per kilometer, tyre wear emission is higher by a factor of over 1,000.

Emissions Analytics believes this could be higher if the vehicle had tyres which were underinflated. Other factors includes the road surfaces, or if the tyres used were from a budget range.

Nick Molden, CEO of Emissions Analytics, adviced that :

“In the short term, fitting higher quality tyres is one way to reduce these NEEs and to always have tyres inflated to the correct level.

“Ultimately, though, the car industry may have to find ways to reduce vehicle weight too.
Whether that leads to specific types of low emission, harder wearing tyres is not for us to say – but change has to come.”
