Worn tires and brakes can also cause pollution levels many times higher than emissions from vehicles using internal gas engines.
Up to now, emissions from vehicles using internal gas engines have always been considered as one of the causes of environmental pollution and global climate change. However, the fact that the wear of tires and brakes can cause pollution levels is many times higher.
This conclusion was made by Emissions Analytics (EA) – a company specializing in providing data and conducting independent tests to assess emissions in practice. Accordingly, the EA asserts that tire corrosion is 1,000 times more polluting than the exhaust of a car.
To come to this conclusion, EA has conducted several tire wear tests through the use of a popular family hatchback nowadays. This car is fitted with a new set of tires and properly inflated. Results showed that for every kilometer of the road, the car emitted 5.8 grams of dust particles, much higher than the prescribed exhaust limit of 4.5 grams / km.
In addition, the level of pollution from the tire is even higher if the car is not enough air or the road condition is worse than in the test or the tire is not good quality. All of these situations are quite common in real life.
Earlier, a 2019 report by the United Kingdom’s Committee on Air Quality also pointed out that NEE – the release of particulates into the air from brake, tire and road surface corrosion. is a major source of fine dust generation in traffic. In fact, NEE accounts for 60% of PM2.5 fine dust and 73% of PM10 fine dust.
Nick Molden, EA Managing Director commented: “The current challenge for the auto industry as well as lawmakers is that there is no regulation or sanction related to this new source of NEE pollution yet. . “In addition to focusing on emissions, we need to use good quality tires, pumped in sufficient pressure to reduce pollution caused by tire and brake wear.”
