EVs Emit More Particulates, One of the Most Dangerous Pollutants

Sharing is Caring!

Let’s discuss particulates from tires. They are another reason to be skeptical of the clean energy claims for EVs.

EV Lie of the Day

The lie of the day is a joint effort from the EPA and the state of California. Both are using rigged tests to get rid of gasoline powered vehicles.

Please note Electric Cars Emit More Particulate Pollution.

The Biden administration is reviewing California’s plan to ban the sale of new gasoline-powered cars by 2035. To get federal approval, California claims it “needs” this ban to prevent harm to public health from particulate matter—airborne particles like dust, dirt and soot. But banning gasoline cars would do little to reduce particulate emissions, and it could even increase them.

According to measurements by an emission-analytics firm, in gasoline cars equipped with a particle filter, airborne tire-wear emissions are more than 400 times as great as direct exhaust particulate emissions.

California calls electric cars “zero emissions vehicles” because they don’t have tailpipes. That is deceptive. Generating the electricity that powers those cars creates particulate pollution, and of course electric cars still use tires, which are made from petroleum. Electric cars weigh far more than gasoline-powered ones, so their tires degrade faster, as electric car buyers are learning. The same analytics firm cited earlier compared two cars—a plug-in electric and a hybrid. The electric car weighed about one-third more than the hybrid and emitted roughly one-quarter more particulate matter because of tire wear. Total direct emissions went up, not down, when the electric car was driven.

But when California’s air agency analyzed the effects of its ban, it used a model that assumes both kinds of cars have the same tire wear. When the public pointed out the error, the agency doubled down, claiming it would be “speculative” to assume that electric cars will continue to be heavier than gasoline cars. The agency mused that in the future automakers could probably “offset” the weight of heavy batteries with unspecified “weight reduction in other components or the vehicle body.”

What’s “speculative” is assuming that electric cars will soon weigh the same as the gasoline cars they replace. Electric cars are 15% to 30% heavier because batteries store far less energy per pound than liquid fuels. While weight differences between electric and gasoline cars have remained roughly constant over the past decade, the only reasonable prediction of trends is for electric cars to get heavier as manufacturers increase battery size to boost range.

Before California can set any emissions standards for cars, it needs the EPA’s approval. But don’t hold your breath expecting scientific integrity. The EPA’s own emissions model falsely “applies the same tire wear emission rate for all vehicle fuel types (gasoline, diesel, flex-fuel, CNG or electric),” completely ignoring the differences in weight.

Why are California and the EPA so eager to push electric cars when they will increase what EPA administrator Michael Regan calls “one of the most dangerous forms of air pollution”? That’s a good question. Perhaps someone should ask them under oath.

The Miami Herald reports New tires every 7,000 miles? Electric cars save gas but tire wear shocks some Florida drivers

At EV Garage Miami, a Sweetwater repair shop that services 90 percent electric vehicles, lead technician Jonathan Sanchez said tires are the most frequent thing customers come in about — no matter what model or make of EV they’re driving. Tire mileage can vary widely of course, but he said he frequently changes EV tires at just 8,000 to 10,000 miles — a fourth or even fifth of typical tire wear on a gas-burning car.

There are a number of explanations for the fast wear — from the way EVs work to the composition of the rubber to individual driving habits and maintenance practices — but vehicle and tire makers and industry experts acknowledge the issue. The tire manufacturer Michelin said conventional tires on electric vehicles consume tires 20 percent faster than on a gas-powered car — a figure commonly cited by EV makers as well — but Goodyear also has said they could wear up to 50 percent faster. Automakers and the tire industry are working on improvements.

Some studies have shown that tires actually have more particle pollution than exhaust, 2,000 times as much. “Tires are rapidly eclipsing the tailpipe as a major source of emissions from vehicles,” said Nick Molden, to the Guardian who conducted one study with Emissions Analytics.

Some premium tires suggested for EVs use softer rubber and have foam injected inside that dampens the sound, akin to trading out hard dress shoes for tennis shoes. Those soft textured tires, while quieter, also can wear down faster. Some car companies also have come up with other creative ways to address the lack of noise by pumping in artificial or ambient sound. Toyota announced a system that simulates a gas engine with pre-recorded “vroom vroom” sound pumped through speakers.


Lies About Tires

Apparently we have another lie. The reported 20 percent extra wear my really be 50 percent for some tires.

If the tire industry improves the tires, it will be an improvement for gasoline powered vehicles too.

Tires Are Made with Petroleum

Michelin says “60% of rubber used in the tire industry is synthetic rubber, produced from petroleum-derived hydrocarbons, although natural rubber is still necessary for the remaining 40%.”

In case you did not know, EVs do not come with a spare. You can order one, but a full sized spare will eat up much of your storage space,

In addition to outright lies about particulates, mileage claims, and tire claims, California and the Biden administration act as if green energy is clean.

But the allegedly clean energy isn’t clean due to the minerals needed for wind turbines, for battery storage, and for solar panels.

Insanity Prevails

Meanwhile, please note Biden Weighs Banning Natural Gas Exports to Save the Climate

The climate fear mongers are pressuring Biden to ban natural gas exports. Let’s discuss the ramifications.

Russia will sell more natural gas as a result.

Reducing exports does not change global demand. It will only shift the source of the supply.

Biden Promotes Climate Change at the Expense of More Global Poverty

More importantly, please note Biden Promotes Climate Change at the Expense of More Global Poverty

The mad rush to deal with climate change, even if it works (it won’t), has a nasty tradeoff (more global poverty).

Add tires to the mix of concerns.
