Quite so. Consider the chatter from Bridgestone: EVs use up tires faster. The first world is moving to EVs. Therefore, Bridgestone will be selling more tires. Is the chatter at Bridgestone intended to juice the stock with the prospect of selling more tires?

Back when I had Corvettes and took them to tracks 4-5 weekends per year Iād go through a set of expensive high performance tires EACH YEAR. Along with 4 brake rotors, a full set of pads, and new brake fluid and engine oil before every event. The point is driving style dictates tire wear more than anything else. Note the person above who has a large SUV with over 60k miles on them. To me that is simply not fathomable. But I guarantee that person is driving in a mild mannered way to get that type of tire (lack of) wear. And if you drove an EV in the same way the tire wear would not be high either. Rolling does not create a lot of wear. Acceleration does (and I mean that in the Physics sense: a change in velocity, up or down, or a change in direction).
I thought it was pretty silly. When I was researching EVs ten years ago, increased tire wear due to the increased torque was a known issue.
Claiming something that something everybody already knows about is āunexpectedā is almost too dumb for words. I guess reprinting press releases is easier than doing journalism.
Tires tyres wear out on high torque vehicles because the drivers are ignorant, lead footed or testosterone crazed, and need training,
Geeeze, this is not difficult.

I learned to drive in cars without power steering. Letting the car roll a little while making tight turns was a necessity. I still do that now for the lessened tire wear.
Iām kind of surprised you didnāt learn this. Iāve always figured you were a bit older than me, when power steering wasnāt as common as it is today.

I probably did, but with 50 years of PS bad habits creep in.
Increased tire wear leads to increased particulate matter in the air. Thus, while EVs lead to lower tailpipe emissions the same can not be said for PM levels. A wear-resistant tire from Bridgestone et al. would thus be useful from a health point of view.
Non-exhaust PM emissions from electric vehicles

Abstract:
Particulate matter (PM) exposure has been linked to adverse health effects by numerous studies. Therefore, governments have been heavily incentivising the market to switch to electric passenger cars in order to reduce air pollutionā¦ In addition, electric vehicles (EVs) were found to be 24% heavier than equivalent internal combustion engine vehicles (ICEVs). As a result, total PM10 emissions from EVs were found to be equal to those of modern ICEVs.

Watch a Formula 1 race. You can see the chunks of rubber from the tires accumulate off the racing line over the duration of the race. The rubber shedding is far far worse on a race car, but the principle is the same on passenger cars.
After the race, drivers will make a point of driving off line during their cool down lap, to pick up the chunks of rubber shed by the tires, to add weight to the car for the end of race weigh in.
True.
It seems odd that some here donāt seem to believe that equivalent ICE and EV vehicles show tire wear at different rates.

Sure. Thatās what cars that can gain speed at 3G, change directions at 4G, and lose speed at 5G will do to tires. Again, as I said above, itās how you drive.
Also note: Formula 1 cars are very light weight. Itās not the weight, itās how itās driven.
F1 tires are also very soft. The combination of the effects you list is to amplify the effects passenger car tires experience.

I drag raced for one summer at the local track. The rubber compound on the slicks were soft enough that you could bury your thumb nail into them. And there were small rubber chunks on the rear of the car after each race.
Motorcycle tires arenāt much better. I usually get about 11 to 12 thousand miles out of them. The rubber compound is also pretty soft. I guess that is for better traction.
Yes. Soft rubber is better for traction in all situations. Dry or wet. Acceleration, cornering, braking.
And hard rubber isnāt. Thatās why I sold our Volt when we moved to Wisconsin.

I was taught to drive like grandma is in the back seat wearing her Sunday best while holding a tray of biscuits and bowl of sausage gravy in her lap.
