Worried about heavy vehicles? The best selling vehicle is the Ford F-series.
Which is 4,500-5,500lbs curb weight, just FYI.
Which comes out 200lb lighter than a Toyota Highlander hybrid.
Dust from car brakes more harmful than exhaust, study finds

Re: Dust from car brakes more harmful than exhaust, study finds
#232Having lived next to a semi-main street through a smallish California coastal city without much rain it is pretty eye opening how much black dirt and junk just coat everything next to the road. Walk down the street and touch a bush or any plant leaf and get a nice black hand in the process. The plants are covered, parked cars get covered and the inside of my apartment was covered. It wasn’t until I moved out that I s…
I live on the second floor near a road and my balcony furniture is always covered in black gunk.
do you have an air filter with an ionizer by chance? those will also do that

Can you share them? Because physics says that damage to roads scales quadratically with weight. Not sure why tires would not experience a similar increase. At the very least, these tires are subject to higher forces due to the heavier weights of EVs. Intuitively, consistently applying higher friction forces to an object would cause higher wear.
The weights aren’t really that much higher than ICE cars, but I don’t think anyone who has owned an EV would say they don’t go through tires faster. They do. How much due to weight, how much due to better acceleration, I don’t know, but they definitely are harder on tires.
EVs use different tires from the factory than regular cars to help increase efficiency, maybe it's about the type of tire?

#234> with their increased weight and powerful torque, they produce a lot more tyre pollution than ICE vehicles. This has been shown not to be true in a number of studies.

> damage to roads scales quadratically with weight
It’s much worse, it actually scales quartically with weight.

#235This is the regular current taboo. Micro-dust from tires and brakes contributes to half of an ICE vehicle’s pollution, with the other half coming from exhaust emissions. The amount of this micro-dust scales with a power of the vehicle’s weight, typically between the square and cube for cars, and up to the fourth power for heavy trucks. EVs are 30–60% heavier than their ICE counterparts. Assuming all other factors rem…
The tyre wear has been tested as well. TLDR EVs don’t wear more tyres than ICEs, except for the Tesla. Wear is larger for FWD cars.

#236The Yale article and the paper both highlight the fact that EVs use regenerative braking and produce less dust. I was worried that this was a rehash of the astroturf campaign from a few years ago focusing on EV weight and how that was so bad for the environment because of tire and road wear. Unfortunately you need to read through the whole thing (instead of the headline and a few paragraphs) to see that information.
Granted, I would still rather them designed for lighter weight. But that’s a separate issue w suv culture which is bad for society and environment in general. Totally would buy a 3000 pound EV around the size of a euro hatch.
There are a few ways to get the weight down. Improvements in battery chemistry, lower range trims, and simply smaller vehicles.

The Nissan Leaf is in the 3000 lbs range and a fairly small hatchback.
Bolt EV is ~3600 lbs

#240How many kilograms of brake dust does the average IC car produce in a year, versus gasoline burned? March of Dimes Syndrome here. We're entering the end of the gasoline car era. Anti-car activists need something else in order to continue kvetching, so it's down to tire and brake dusts, battery recycling and whatnot. When that is solved, it will be about the harms of exterior paint, and inhaling the "new car smell". T…

This seems to be mostly a US problem, I only really see people from the US worried about this...
As someone from the UK who travels on two trains and a bus both ways (6 journeys total) most weekdays to university, I never had any problems with other passengers, I guess very occasionally there might be a loud baby or something but then you can just put headphones in, and the worst thing that ever happened to my property is my bag got accidentally handed into lost property when I wasn't paying attention because I got on really early and the staff assumed it was left there from the last trip
