Tires create fine dust particles that seep into the ground as they wear on the pavement
Because electric vehicles are heavier than comparable gas-powered vehicles, their tires wear out faster
The level of tire pollution created may be worse than the exhaust emissions of comparable vehicles
A new study by Emissions analysis found that electric vehicles are not as environmentally friendly as they appear due to the effect of their heavy weight on their tires.
Automotive tires are a major source of pollution created by the transport sector because the rubber they are made of creates fine particle dust as it breaks off onto the road surface.
This dust settles on the ground and can seep into the water table, which can lead to health problems.
The problem with electric vehicles is that their battery pack adds a very large amount of weight which makes them much heavier than comparably sized vehicles powered by gasoline engines.
This extra weight means electric vehicles wear out their tires faster and can create up to 400 times more pollution than the tailpipe emissions of a comparable gas-powered car.
This means that all pollution combined, electric vehicles can be more damaging to the environment in daily driving than competing cars equipped with internal combustion engines.
The news isn’t all bad, however, as the study also found that careful drivers who accelerate slowly and use the regenerative braking features of their electric vehicles can limit tire wear to a level that reduces pollution under the car. exhaust emission level.
In addition, several tire manufacturers are working on new tire materials that are more environmentally friendly. For example, Goodyear is testing biodegradable tires, Continental has presented a concept made of 50% recycled or renewable materials and Michelin is currently marketing the first carbon neutral tire.
