- EVs weigh 30 percent more than petrol cars, causing tyres to wear out faster
- The tire tread releases toxic particles 400 times greater than exhaust emissions

Electric vehicles may release more pollution than petrol-powered vehicles, according to a report that has recently resurfaced.
The study, which was published in 2022 but has begun circulating again after being cited in a WSJ op-ed, found that brakes and tyres release 1,850 times more particulate matter compared to modern exhaust pipes which have filters that reduce emissions.
It found that EVs are 30 percent heavier on average than petrol-powered vehicles, which causes the brakes and tyre treads to wear out faster than standard cars and releases tiny, often toxic particles into the atmosphere.
Hesham Rakha, a professor at Virginia Tech told Dailymail.com that the study is only ‘partially correct’ because even though EVs are heavier, their tyres will emit more microplastics into the air, but this could also be true for sedans versus SUVs.
Rakha said it is very challenging to determine the difference between the amount of microplastics emitted from EV tyre treads and petrol-powered vehicles because you have to separate the microplastics that are already in the air from other sources with what’s coming off the tyres.
Rakha and his team at Virginia Tech are in the process of conducting field tests to determine how much microplastics are emitting from EV and petrol cars by using traffic simulators that will mimic an urban setting.
He added that he doesn’t expect there to be a major difference between the EV and petrol-powered vehicles, saying that they haven’t measured it yet, but expect the difference to be about 20 percent.
This doesn’t mean that people should gravitate away from electric cars because they ‘are more efficient depending zero emission,’ Rakha said, but added the caveat that ‘it also generates a lot of CO2 when charging your vehicle.’
EV batteries weigh about 453kg, and can result in tire emissions that are nearly 400 times more than exhaust pipe emissions.
Particle pollution can increase health problems including heart disease, asthma, lung disease and in extreme cases, can lead to hospitalisation, cancer, and premature death.
New petrol-powered cars are created to be ‘cleaner,’ by updating the trims of their internal combustion engines to include particulate filters that reduce emissions.
The EVs increased weight due to their lithium-ion batteries cause the tyre treads to wear faster, ultimately producing more emissions.
The study, conducted by the firm Emissions Analytics, said the main difference between exhaust pipe and tyre emissions is that the majority of particulate emissions released from the tyre go directly into the soil and water, while exhaust negatively affects the air quality.
The effects of tire composition come down to the materials the tyre is made from, the study reported.
Light-duty tyres are typically made from synthetic rubber which is developed using crude oil natural rubber adds fillers and additives, some of which are recognised carcinogens.
Emissions Analytics tested the tire wear on both EV and gas-powered vehicles after driving them at least 1,600km.
The researchers used a sampling system to collect particles immediately behind each tire and then measured the size of the particles emitted from the tread.
It found that the greater the vehicle’s mass and weight, the more rapidly the tyre particulate emissions would be released due to the increased torque between the tires and the road.
A separate 2020 report by the Emissions Analytics firm said that tyres are likely to be a major concern in the coming years as ‘consumers switch to bigger and heavier cars.’
‘Research shows they contribute to microplastic marine pollution, as well as air pollution from finer particles,’ the report continued.
Electric vehicles are not a viable alternative and don’t decrease the carbon footprint, if one wants to believe that concept is legit. The raw materials needed to manufacture batteries do not exist in sufficient quantities to provide for even a small fraction of what is needed to replace gas and diesel engine vehicles.

Excerpt from Forbes article :
There are 7.2 million battery EVs or about 1% of the total vehicle fleet today. To get an idea of the scale of mining for raw materials involved in replacing the world’s gasoline and diesel-fueled cars with EVs, we can take the example of the UK as provided by Michael Kelly, the Emeritus Prince Philip Professor of Technology at the University of Cambridge. According to Professor Kelly, if we replace all of the UK vehicle fleet with EVs, assuming they use the most resource-frugal next-generation batteries, we would need the following materials: about twice the annual global production of cobalt; three quarters of the world’s production lithium carbonate; nearly the entire world production of neodymium; and more than half the world’s production of copper in 2018.
AND THIS IS JUST FOR THE UK . Professor Kelly estimates that if we want the whole world to be transported by electric vehicles, the vast increases in the supply of the raw materials listed above would go far beyond known reserves.
The environmental and social impact of vastly-expanded mining for these materials — some of which are highly toxic when mined, transported and processed – in countries afflicted by corruption and poor human rights records can only be imagined. The clean and green image of EVs stands in stark contrast to the realities of manufacturing batteries.
Not to mention the detrimental impact they have on the nervous, cardiac and reproductive systems, it is comparable to travel in a microwave oven.

I am a fuel economy fan – I love cars that get ultra high mpg. I’ve owned 9 Geo Metros and currently drive an 8th gen Honda Civic. My job requires much driving, I have a Scan Gauge III – fantastic tech – touch screen gadget that plugs into the OBD2 connector and tells you instant MPG and a hundred other things. I use hypermiling techniques – my goal is to burn the least fuel possible and keep my hard earned money for myself.
Some bullet points:
A Tesla weighs 3X of a Geo Metro. That is huge. 6000 lbs vs 1700
Tesla tires cost 3x more
Teslas have to be recharged and have a short range
Teslas can auto ignite and turn the occupants into charcoal, read the facts:
https://www.tesla-fire.com/
A Geo can easily get 500 miles on a tank (10,6 gallons) The record is 750. I routinely got over 60
A Geo Metro is fantastic on mountain roads and in the snow. with chains a geo metro is unstoppable
A Geo Metro with 1/8 tank of gas can still get you 100 miles. When the gas gauge is on the red line zero, that indicates 8 gallons burned – giving you 2.6 in the tank. 50 mpg x 2gal = 100 mile range
A Geo has no power anything – and is driveable with engine off. You can coast all day with no power and still have steering and brakes.
If you drive 5th gear at 35 mph the car gets 75 mpg. I spent years hunting Idaho on back roads, I could drive all day for $10. And yes, a geo can carry a mature buck and an elk that is cut into pieces. The elk weighs almost as much as the car.
A metro with it’s tiny 3 cylinder 1.0 liter engine is a piece of cake to work on – tons of room – the starter, alternator, head, thermostat, radiator can be replaced with no trouble – the car is a dream for maintenance. Even the struts, brakes, headlights are a piece of cake
The new mitsubishi mirage is the new metro
