EV's have 100% reduction of NOx/tailpipe VOCs, 100% reduction in soot/tailpipe particulates, 70% reduction in brake pad dust (due to regenerative braking), in exchange for 25% increase in tire wear.
Vehicles are capped at emissions of 3mg/mile of particulates and 30mg/mile of VOC's. Something like 1-2mg of tire material actually becomes airborne PM10 particles every mile (and only about 10% of that for PM2.5 particles).
So, EV's really do a great job reducing emissions from 35mg/mile to <2mg/mile (PM10) or even <0.1mg/mile for PM2.5. A 95%-99.8% reduction in air pollution near highways would seem absolutely fantastic for me and my children!

I replaced the tires on my Tesla model 3 at 74,000 km and they still had tread above the indicator bars. I'm now at 140,000 km and the tires look great, the back ones look like they're only about halfway done. I might be an outlier but my previous Subaru needed tires every 50,000 to 60,000 km.
Needless to say, the brake pads have never been touched and when I saw the left front one at around 110,000 to 120,000 to patch that tire, it looked like it was just installed. The regen braking almost completely eliminated the brake pad or rotor as a wear item.
Yeah, aren’t the EV tyre’s compounded differently in some way to account for the extra weight?
If the weight on each wheel is greater I’d have assumed the tyre would need to be harder, for the same performance.
I would have assumed that would counter the otherwise additional wear, but I keep hearing EV tyre pollution is higher and yet everyone who owns one has always said they aren’t changing tyres an more than they did on their combustion cars.
Given that tires have a range of warranties from 40,000 miles to 80,000 miles ... it's possible that the tires are wearing 25% faster but the consumers aren't noticing because it's still around the normal 40k-80k mile range.
No matter the warranty - I still notice when I replace them.
And the warranty requires proof of periodic rotation. If the tires are wearing evenly, as is the likely case for a new vehicle, then rotation costs significantly more than the pro-rated rebate.
One might similarly note the awe-inspiring destructive power demonstrated by tanker trucks of fuel catching fire and causing interstate bridges to collapse.
You're speculating about something that hasn't happened, using something that doesn't exist; no body is driving batteries large enough to destroy a bridge about.
They are driving liquid fuel tankers that can do that around regularly.
Also consider that as battery tech improves new chemistries lower the risk of fire even more. E.g. sodium batteries are very stable right now and solid state will improve that further. There's no way you can make petrol less flammable.
You're going to have to face facts, battery powered vehicles are safer than petrol powered one.
Consider that every single human being on the planet carries around a lithium battery in their pocket, at a large percentage of those batteries have experienced such damage that would destroy the glass screen on those devices, and yet people are not bursting into flames regularly, and even the defective batteries that Samsung distributed for a while only made events extremely rare.
