Tire wear is a matter of friction. Higher weight, higher friction, thus more wear. In this isolated instance, electrical cars are likely to be worse off than regular cars due to generally higher weight. Perhaps this is offset by regenerative breaking systems though. I'm sure you could make that argument on other parts of the EV as well.
Outside of isolated areas like that, I would be seriously surprised if electrical cars comes worse off than gasoline cars on the whole. There has been some talk about CO2 emissions made when making hydro electric dams, for instance, but then there's also CO2 emissions when making oil platforms, and so on, so IMHO those kinds of discussions quickly become very theoretical. Either way, I'm sure EV's are better off in terms of local emissions, meaning that they reduce local smog, and so on.
On the other hand, EV's can very well run on coal, if that's how your local electricity is produced. In that case, how well EV's do environmentally speaking is due to the total effort made by society. For that reason I'd love to see a comparison of gasoline and diesel versus coal. Which one is the cleanest?
AFAIK there are some real issues with the way lithium is mined for the batteries, however, that doesn't strictly involve emissions. So there are many pros and cons in the debate on electric vs gas cars that aren't obvious to the casual on-looker.
I don't have a particular horse in this race myself, but I do note that those who do, tend to offer arguments that are more strongly coloured by their preference.
Personally environmental safety isn't the only deciding factor. There's also such things as cost and reach. And I don't just mean how many miles a car can run on one tank, but also its longevity. On the whole it seems to me that EV's have a higher capital cost (up front cost), that might not make up for the savings you make by running it.
On the whole it seems to me that gasoline cars have far better overall longevity than EV's, with the offset that EV's are cheaper to run, though with slightly more hassle in the "refuelling" department. For me personally, winter cold is an issue, since it severely affects battery capacity. On the other hand, those Teslas do look pretty cool.

- heresie-dabord 5y ago> electrical cars are likely to be worse off than regular cars due to generally higher weight. Given that a Nissan LEAF weighs about the same as a Honda CR-V, and that there are many EVs that have the same weight or are lighter than the Nissan LEAF, I would say that you are considering only a select group of EVs.

Here are some examples of popular electric cars and how much they weigh in order of weight: Model X Long Range – 2459 kg without passengers or fuel (7 adult capacity). Tesla Model S Performance – 2241 kg without passengers or cargo (5 adult capacity). Tesla Model S Long Range – 2215 kg without passengers of cargo (5 adult capacity). Model 3 Performance and Long Range AWD – 1847 kg without passengers or fuel (5 adult capacity). Nissan Leaf – 1775 kg without passengers or fuel (5 adult capacity). Chevrolet Bolt – 1616 kg without passengers or fuel (5 adult capacity). Opel/Vauxhall Ampera-E – 1611 kg without passengers or fuel (5 adult capacity). Renault Zoe, 44 kWh – 1480 kg without passengers or fuel (5 adult capacity). Hyundai Kona – 1399 kg without passengers or fuel (5 adult capacity). BMW i3 – 1343 kg without passengers or fuel (5 adult capacity). Based on this, and the upcoming plans of many automakers to launch pickup truck and SUV type EVs, I would say that a significant portion of EVs will be heavier than the average car on the road currently.
- heresie-dabord 5y agoThe EV market is about 2% of car sales in the US. I doubt that we would be right to predict double-digit growth happening suddenly. A Ford F150 (the most popular pick-up truck) weighs about the same as the Tesla Model 3. The top-selling vehicles in the US are all pick-up trucks. The Toyota Camry (a popular sedan) weighs about the same as the Nissan LEAF. The Prius Prime is also in this weight range. A Honda Fit (a popular small car) weight about the same as a Smart EQ. Small cars are not what US consumers are choosing. Your argument is a hypothetical projection of Tesla-class EVs into a very large market-share. In reality, consumers are choosing larger, heavier ICE vehicles.
