A place to discuss problems of car centric infrastructure or how it hurts us all. Let's explore the bad world of Cars!

Higher weight and higher torque means tires wear faster on EVs. That’s physics, and the theory is backed up by real world evidence.
The average difference between EV and a gas car is around 300 to 400 kg. With an average weight of a small car being around 1500-1700 kg, and an electric variant of the same car being 1800-2000 kg, the difference is basically nothing. It's, like, two large dudes. And that's smaller car, the difference in big SUVs becomes almost negligible. It's so nothing, especially compared to all the particles EVs don't emit, the only reason we keep talking about is astroturfed bullshit from the conservative car manufacturers. It's from the same playbook as wanting to get rid of wind turbines because sometimes they kill birds.
400kg makes a huge difference. Road damage increases proportional to the fourth power of axle load, which is like 2x in your example.
For the smallest car on the market it's around 20%. It rapidly gets smaller the bigger the vehicle is. Exchanging lack of tailpipe emissions for less than 20% increase in road damage is nobrainer.
The flatter torque curve (peak torque on electric cars is usually very comparable to ICE) is irrelevant, unless you are a shitty driver who treats the gas pedal like a two position switch.
If you were really concerned about higher vehicle weight, trucks are much worse so let’s start there
Yeah, it also applies there. It’s just a fact - heavier vehicles have more tire wear.
Trucks are typically carrying tons of goods (except those awful LTL cases where the 50' trailer is carrying one pallet)
Cars (mostly SUVs these days) are usually just carrying 80kg of spongy meat.
Those are not even the same levels of utility
EVs are about 20% heavier than the equivalent gas powered car and offer the same utility.
Full sized pickup trucks are 50-100% heavier than cars, are the most common vehicle in most of the US, and is “ usually just carrying 80kg of spongy meat.”. They are usually exactly the same levels of utility, plus don’t have any environmental benefits
Things can be both true and irrelevant. Astroturfing highlights irrelevant things to the point of relevance so they get in the way.
Like Trump's"feud" with Rosie O'Donnell. It exists, but means literally nothing and is just there to distract from actual conversation.
I feel it’s fairly relevant with the interest in microplastics lately.
