It's only common because Tesla is popular. Other brands put reasonable tires on.

Anecdotally, I own a Kia EV6, and had to get new tires within two years, under 20k miles. I leave it in eco mode, so acceleration is nerfed, too. We’ll see how long the new set of Michelin Defenders last.

Some models of the EV6 come with Pilot Sport 4S tires which is absurd.

I pick up a bad screw every year from careless Ute drivers with leaky toolboxes and have to throw 1-2 tyres in the bin. Tyre wear isn't that important to me.

That's your choice.

We jack the car, pull the wheel, extract the screws, and use a tyre plug kit.

Tyres with inner tubes can also be repaired, that's slightly more involved.

We should obviously ban combustion engine cars, at least starting with cities. I can’t think of a single clearer win for air quality.

I would love to have gone electric (bought a car in September) but I rent and don't have any way to charge at my residence. How do we solve the renters-that-cant-charge-their-cars problem?

No, it’s not a joke. EVs are heavier vehicles, and it’s common for EV owners to have to change tires much more frequently. https://www.cars.com/articles/do-evs-wear-through-tires-more...

I have a model 3 and still running my original set of summer and set of winter tires. 6+ years. I just don't put pedal to metal every time I accelerate.

Yeah maybe starting with what they’re doing in places in Europe where gradually emission requirements become more strict.

lol no shit sherlock.

I've owned a Pirus (hybrid), Camry Hybrid and now a Rav4 Hybrid plus a MG4 EV.

The rav and MG4 are too new to count, but the other two I owned for about 10-13 years each.. we NEVER needed to change the brake pads.

Not once.

If you're having to change the brake pads on a car like this, you're a leadfoot with no core strength issues :-P

Sure, first we spend a trillion dollars for over capacity electrical distribution grids and generation plants.

B100 is almost carbon neutral, and has the energy density necessary for commercial logistics. Finding responsible manufacturing methods is far more feasible.

EV only make sense with distributed generation like home solar. =3

If all of us renters were forced to convert to electric there’d never be an open charger in any city again for the next five years, because no landlord will voluntarily afford that cost, and no municipal region can pass a ballot measure to afford that cost. California’s impending ban of combustion car sales hinges wholly on a magical DC-charging network that doesn’t exist in U.S. cities yet (i.e. at parking meters), only at U.S. personal dwellings.

I would love to switch to electric but at current charging times and absolutely horrendously incompetent grid deployments, there’s no way all of the thousand people in my building could, much less the million other renters in the city. (And certainly transit can’t cope with us either, given the continued homeowner hostility to paying taxes for such things.)

What city has charging available for an average of greater than one spot per five hundred multifamily-housing residents? What parking garages anywhere in the U.S. have 25 or more electric vehicle chargers per 100 daytime and/or overnight and/or reserved parking spots, in order to diffuse the grid cost through trickle charging? What funding model is proposed to ensure that’s built whether corporate garage owners like it or not? How will states who depend on fuel tax to keep roads in repair avoid cutting off city services to suburban outregions when their asphalt budgets crater?

Technology has downstream effects, and it’s not as simple as “buy a Prius” when you consider U.S. non-homeowners. (I assume the prospect for India electric conversions would be much worse, too.) “Ban combustion vehicles” is a lofty goal, but until the charging grid problem is solved, it’s an unattainable one.

An an EV owner, I can testify that the tyre wear more than makes up for the reduction in brake dust. I’ve had to change tyres every 10K miles.

Presumably this is a joke. Mine lasted 5 years, 50k miles.

I assumed instead they were soft compound tires with a low treadwear number. Nice for "sport" driving but they wear very quickly.
