Tire emissions and health concerns

Home > Industry Analysis > Content

【Summary】EVs, while eliminating tailpipe emissions, are contributing to pollution through the wear and tear of their tires. The rubber particles emitted from EV tires pose health risks as they contaminate the air, water, and living beings. Scientists have linked a chemical in tires to premature deaths of salmon, emphasizing the need for more sustainable tire options.

Buyers who frequent the online forums for Rivian's electric pickup and SUV have been expressing a common complaint - the tires wear out too quickly. One driver from Colorado loaded his truck with two motorcycles and embarked on a journey. After traveling approximately 6,000 miles, he noticed that nearly a tenth of an inch of rubber had worn off his front tires. The rubber that was lost now exists as microscopic particles somewhere. It appears that other electric vehicle buyers are facing the same issue.

While electric vehicles have successfully eliminated tailpipe emissions, they have inadvertently contributed to another form of pollution that is causing concern among scientists and environmentalists. The heavy weight of these vehicles is exacerbating the problem.

It has long been recognized that tires emit pollution as they travel on roads. The friction between the tires and the pavement causes tiny particles of rubber and other substances to break off. Over time, these particles, some of which are as small as a human cell, find their way into the air, water, and even living organisms. Scientists in Washington state have discovered a link between a chemical called 6PPD, which is used in all tires to prevent cracking, and the premature deaths of salmon. During rainstorms, the 6PPD washes off the roads and into streams, where it is then ingested by the fish.
