There's nothing categorical about EVs that make them eat tires. The aggregate data about average EV tire life is skewed by the relative popularity of and poor choices made by Tesla.

Apart from the increased weight and torque

Other than that, Mrs. Lincoln... how was the play?

Torque and pedal response are just choices made in software. The weight is not as important, given the example of the Bolt EUV that weighs ~1700kg and has normal tire life.

> Torque and pedal response are just choices made in software

Yes which is due to the flexibility of EVs. The problem then is that customers are going to prefer buying vehicles with greater torque and manufacturers have little incentive to not provide EVs with high torque.

A lot of it is based on driver behaviour as it's quite feasible for ICE vehicles to be driven to burn rubber or make donuts.

EVs are heavier but it may not be that dramatic, M3: ~3500-3800lbs, Honda Civic: ~3000lbs

The torque is real, though, but I think this is what the earlier commenter was getting at regarding bad choices made by Tesla: there is no reason "chill mode" isn't the default, which makes a Tesla drive more like an ICE vehicle. Most other EVs I've driven don't go full torque by default, so seem to have made a better choice there.

In personal experience, I went about ~45k miles on 4 new tires in my Model S before I replaced them. A bit sooner than I would have in my Prius but not much.

I also don't take off from a green light as if I were in a drag race, which probably helps.

But we agree that heavier cars have more tire wear.

And EV cars tend to be heavier then comparable combustion cars.

Model 3 Curb Weight: 3,552–4,048 lb

Model S 4,323 – 4,960 lbs

Model X 5,248 lbs

Model Y 4,209 - 4,363 lbs

So what’s your point?

That EV cars exist that are less heavy than the average car?

That’s not why I said, I said comparable combustion cars are less heavy than their EV counterpart.

If that’s your point why didn’t you provide any comparisons to equivalent ice models?

Let’s look at some comparisons since that is your point:

> Starting with the Tesla Model 3 weighing in at between 1777Kg and 1840Kg

> A comparable ICE car the BMW 3 series 1570Kg - 1965Kg

> And another ICE car the Mercedes C class 1665Kg - 2190Kg

> And finally another EV the Ford Mustang Mach-E 1993Kg - 2218Kg

So there’s not much in it. EVs do tend to be 10-15% heavier for the same model in EV vs ICE but the point is brought up constantly as if they are twice as heavy, or at least significantly heavier. In reality picking a model 3 would for your next car would bring the average weight of US new cars down which I think is interesting, no?

If you include e-bikes and e-scooters as EVs, sure. If you mean cars and trucks, the F150 Lightning, the EV6, the Ioniq 5, the EX30, and every other vehicle is heavier than its ICE counterpart. The motors are inherently torquier too.

disclaimer: I drive an electric car but would sell it in a heartbeat if I could use transit or bikes to safely and efficiently get to work, the grocery, and the doctor.

They aren't inherently torquier. That's a design point.

If they're heavier, they inherently need more torqure to have acceleration competitive with ICE vehicles.

It's Lenz's Law, friend. It's as much a design point as a=F/m. Because of it, induction motors and magnet synchronous motors generate more torque at 0RPM than any combustion engine I've heard of.

You could have software limiters, but you'd need regulatory mandates for that. Actually, I support that. 3+ ton trucks with a sub 4s 0-60 shouldn't be street legal. Or they should at least require a special license and liability insurance.

All EVs already use limiters because, as you correctly noted, just shorting the battery across the motor will rip the axles off and set the battery on fire. The question of whether an EV should put down grip-limited amounts of torque, or should limit itself to .5g at most, is a question of tuning.

So... you're saying electric motors are inherently torquier?

You have a 4500+ lb car with 0-60 acceleration of 2.x to 4.x seconds and crazy torque, if you drive EVs like a teenager you will eat your tires after 10-12k miles.
