Electric cars are not THE solution.
I've been saying this for a while. Not only that, but electric cars are substantially heavier than their ICE-powered equivalents, meaning both tires and roads wear out more quickly. Plus, there's a ton of pollution and other environmental damage caused by battery production that at least partly offsets the lack of tailpipe emissions.
As loathe as I am to admit, because I'm a car enthusiast and I enjoy driving, cars cannot be the default mode of transportation everywhere indefinitely; they will always need to exist, but should mostly be for small centres with no capacity to implement transit infrastructure and last mile type of things.
The battery production pollution is an issue, however one thing to keep in mind is that once the minerals are out of the ground they can be recycled, unlike drilling for oil. When looked at on a long timeline the battery for an electric vehicle is a lot cleaner than everything needed to power an ICE vehicle.
That said, there's always room for improvement and we should never get complacent. But we don't avoid innovation just because it isn't perfect.
It's not just tailpipe emissions, though - there's an entire supply chain of extraction, shipping, refining, delivery that's needed to get fuel to your local gas station.
The fossil fuel industry always wants to compare the total environmental damage of an EV with just what comes out of the tailpipe of an internal combustion vehicle. Don't fall for it.
This should be the definition of ‘letting perfect be the enemy of good’ Please stop using false oil lobby talking points to attack the transition to electric cars. Electric cars are an order of magnitude better for the environment than petrol/diesel, stop fighting big oils battle for them. Now let’s talk about how we can reduce road journeys through public transport, and reduce environmental impact of tires.
Is that true about the tires though? Electric car tires are designed to be substantially tougher because of the increase in weight, do they actually shed more material?
There's no such thing as an "electric car tire." They just use standard passenger vehicle tires rated for the appropriate weight class.
"Tougher" just means they handle more weight by holding higher air pressure, so they'll have more layers of steel, kevlar, canvas, etc. The materials that makes contact with the road still wear the same.
You can't really engineer away the need for friction, and if there's friction there is going to be wear.
If EV tires were much better than normal tires with the same grip levels and somehow magically less wear, all tires would adopt that technology.
Not that I'm a materials scientist, but EV tires don't seem much different than other "economy" tires, other than a higher load rating.
You have answered your own question. They are built to be tougher, by using more material.
They still shed a proportional amount of material for the vehicle weight.
Not only that but if they get damaged due to trauma prior to end-of-life (such as a puncture of pothole damage) that is a lot more material that is going to landfill (or tyre “recycling” in countries that have it).
They use the same materials, they’re usually just thicker. If you get one of those heavy boat luxury cars you’ll put the same tires on them. They shed material at a faster rate, but they have more material to compensate.
