Tires on heavy EV’s wear out faster

Well this should make the tire manufacturers very happy.

But what about the extra microplastics emitted by EV tires?

https://www.earth.com/news/hidden-costs-electric-vehicle-tires-emit-20-more-pollution/

What about the damage to secondary roads that normally don't have heavy weight traffic on a daily basis?

Just means more expense to small communities for road maintenance, surely the manufactures will contribute for that. Oh wait they will just raise the GASOLINE tax to make up for the increased road damage repairs so the ICE's can pay for it and the EV's get a free ride. rant

They're also too heavy for current guardrail systems:

Report on new study.

That news story is a bunch of overly dramatic crap.

Ooohhhhh.... 7000 lb Rivian busts through a metal guard rail when perpendicular and traveling at 60 mph.

Gee, REALLY?

A Ford Focus will bust through one at the same speed.

Here's an idea! Let's repeat the test with a 9000 lb 4 door 4x4 SuperDuty! I bet it takes out both rows of K rail catch barrier.

The Tesla trick? It went under the rail? At a 45 degree angle?

How about we try that with a low nose sedan. Mercedes GT63 comes to mind. It would tuck a bumper under that rail and lift it up, too. Those toothpicks won't stop a car when you're smashing them one at a time.

I'm no EV poster boy but even I can smell the BS from here.

My takeaway was how well the truck survived the impact and the likelihood of limited injuries to any occupants.

It also looks like the testing crew underestimated the safe distance needed for their video cameras.

On a separate note, I had tires delivered to Tires Plus directly from Tire Rack, for install.
During checkout, there was a special disclaimer, "We don't mount EV tires"

Are the tires, or balancing "special" on an EV?

EV's are heavy as heck too, their weight it all at the bottom too, so the tires are special. Have you priced EV tires? Just another reason to never own one...

Took a look at Tire Rack, 2022 Telsa S, ranged from $1300 to $2200 for a set of 4, ouch!

I paid $550 for 4 tires on my 06 Mustang.

I have several customers with a Tesla we have mounted tires for. They are averaging 15-20k miles on the ones I see. One customer is running cheaper overseas tires on his with no ill effects. Same load rating as the OE tires.

Goodyear did a study that came out about two years ago. Concluded 50% greater wear for evs. Some eco dorks told me Michelin was saying 15-20% greater so it was bogus. Except a quick google search revealed it was a Michelin exec taking out of his rear end before any real testing took place.

That’s my second favorite ev cult member psychobabble fallacy. Favorite is how they like to bring up how your house probably already has a dryer plug, so having a charger is no big deal. Just demonstrates their lack of understanding what is going on with electric and their devotion to making one guy super rich. “But, but, dryer plug. Dryer plug.”

So tire wear is mostly controlled by driving habits, accelerating, cornering and stopping, steady speed tire wear is not greatly affected by vehicle weight.
So are EV drivers speed racers incognitio?

Oh yea let me open the window in my laundry room and you toss that big a$$ cable in. Oh wait, my laundry room doesn't have a window. Lucky me. My breaker box is in the garage. It should be easy to wire in a charging station. Good thing it's not on the opposite end of the house. That cable is expensive. Oh Oh, my house is already all electric and there are no open slots in the breaker box. I bet I would need a bigger service and breaker box to add that much load. Whew, good thing I have NO intention of EVER buying an EV.

no offense but wrong.
The number one factor is the load, the weight. As you put more weight on a tire, it's going to wear out faster. And as I mentioned before, some of these EVs are almost 30% heavier than their counterparts.Jul 28, 2023

Studies are also finding this accelerated wear is worse for the environment than tailpipe emissions LINKY

HMM I can see tire debris filters / collectors in our future. Then they'll need servicing. I hear Fram's already working on a solution LOL

Ok, I offended, now can you back up your claim that my comment in red above is "wrong"? I omitted the word "level" above since climbing up or down a mountain for instance at a steady speed would elevate tire wear if load was increased, as a Florida resident forgive me, that is the exception here.
You also know a tire sitting there with or without a load will suffer the same wear, none, until it is driven, right?

Actually it's the size of the tire(s) contact patch and how much weight is concentrated per square inch time the tire air pressure (or whatever square measurement you want to use inch, metric, etc.,).

You can actually weigh a car by determining each tire's contact patch in square inches then multiply that contact patch by that tire's current air pressure. If the contact patch is 20 square inches and the tire pressure is 40 PSI (Pounds Per Square Inch) then that tire is supporting 800lbs. If it's the same at each of the four wheels (tires) then the vehicle weighs 3200lbs. Simple math. That's how they weigh giant mining trucks.

Do EV's run higher tire pressure and/or are the contact patches larger in square inches than non EV's or lighter vehicles?

That’s the type of stuff I end up explaining to people all the time. Most have zero, or less than zero, understanding of electricity. I finished out the basement and ran a wire from one end of the house to the other for a car charger. We will have a gun to our head soon enough and I didnt want to tear out everything or run it along the outside.

That piece of wire cost 476 dollars, three years ago. After 8% inflation, then 4, now 3, I’m sure that same wire is 1200 bucks.

Luckily I had plenty of room in the breaker box. Most people don’t have that kind of space and a 500 wire will be least of their worries. But hey, I hear if you have a dryer it’s all good.

As I was growing up there were huge numbers of overloaded coal trucks and these trucks were tearing up the blacktop that had been laid down at considerable $ over the mountain gravel roads.

My grandfather and father were definitely in the “good roads” camp and further understood that overloaded coal trucks also wore out their tires “way before their expected tread wear life”.

It is “penny wise and pound foolish” to increase your $/ton by getting horrible tire life and then also pay more $/hour to drivers who have to slow down on torn up roads.

A similar thing can happen on a railroad if you overload railcars but in that case you destroy the rock roadbed below the steel rails and cross ties. This happened when they foolishly went from 70 ton to 100 ton railcars. Even worse the 100 ton railcars were too tall and unstable. One turned over and killed a friend of mine.

Caterpillar used to run free “Equipment Schools” where one section was how to calculate maximum load on those HUGE haulback truck rubber tires.

CAT believed that most operators were getting less than 50% tire life. Here load and speed both contribute to internal rubber temperature, which has a sharp upper limit. Drive just 2 MPH faster and the tire self destructs.

Robot driven huge haul trucks have a “hidden advantage” that you can command a robot to never exceed a speed that human driver “Joe B. Yahoo” ignores.

My father also was a big believer that every house should have been wired for 3 Phase electrical power, and that 400 HZ 3 phase has many advantages, as the US Air Force found.

All an interesting antidotal read, but I am unconvinced there is even a correlation between EV tire wear claims and the stories shared above regarding tire temps, overloaded coal trucks off road, 2 mph speed increases, and grandfather stories from a time tire tread technology still had brand names as their tread patterns.

I've been driving an EV for 7 years now. Never noticed any issues with tire wear. The brakes last a lot longer on an EV since they use regenerative braking. I've never had to replace brakes on my EV cars even though I've driven them for years now.

read the LINKY article in my post, I'll post it again LINKY CLICK HERE

lol I guess you know more than the rest of the world. Loading makes a huge difference. Always. And he’s right spot on about the coal stuff. Leonard Lawson made a kings ransom building roads over and over and I’m sure the coal sticker for running over 80k was his idea slipped to a bought and paid for gubnor.

Needs fact checking and or BS checking but supposedly most of the info is from the "sponsoring" tire manufacture. Just FYI and I posted this in another thread so we can continue the

Good explanations in video.

Could not spot any deliberate “spin.”

( haha - spin - when subject is tire related)

Maybe those South Korean 155 mm rounds are “a blast” to fire off ?

Maybe I'm not as gullible, or I have never read about an EV overloaded with coal driven off road.

Spin or propaganda is simplistically defined as: "The Intentional selective use or distortion of facts with the primary purpose to sway, alter, or change another's opinion or position of the matter at hand,"

I watched the video and mainly focused on tire wear aspects mentioned, The only thing that caught my eye was the selective aspect, and the intentional part would hard to proven if even true.
That being said, keeping in mind my original claim stated here a couple of times "tire wear is mostly controlled by driving habits, accelerating, cornering and stopping, steady speed tire wear is not greatly affected by vehicle weight." was never addressed directly in the video.
What was touched on in the video was that a heavier vehicle of any design can have greater tire wear accelerating, stopping and cornering, or what can be called "driving habits". I can't speak for anyone else, but I would guess less than 2% mileage wise of my driving is accelerating, stopping or cornering.
It was also mentioned but not followed up that alleged EV's have narrower tires for less aero resistance, logic would suggest they comparably would wear faster by being narrower,
It was clearly noted that EV have greater instant torque, controlled by the "gas pedal", again a driving habit. It was also mentioned a EV tire with the greater weight must be able to handle a panic stop, which would incur greater tire wear in an EV, but still a driving habit related. I can't remember making a panic stop in or say 75K? miles.
I also submit if one accelerates with nearly the same energy in any vehicle of any comparable or greater weight, tire wear will be nearly the same, only the time needed to reach the target speed will differ.

PS My daughter has had a Prius for years, She loves it and drives the wheels off of the thing, way more aggressive than any petrol past vehicle, and brags about the high mileage.
I wonder with the very low COG and inherent less body roll, they develop less sense of their cornering speeds?

Nope, you just muck up threads with your rhetoric for no reason, here insinuating you know some engineering trivia the rest of the world does not. Pretty much spot on for your behavior, which has been noted here and on at least one other forum- by a jury of your peers. I have no idea how you got to an ev being loaded with coal, I do award you points for the most tortured nonsense I’ve seen posted on the internet so far this year.

So we agree then, I'm maybe less gullible then others, while we are off topic? LOL
Sorry you can't figure out my reason, even when its right in front of you.

WSJ editorial Monday:
Now the Climateers Want Your Tires.

In a nutshell,
they want the power to ban any tire that does not meet what they judge is “lowest rolling resistance.”

This could ban snow tires, mudder tires, maximum cornering tires, etc

What could possibly go wrong......

if they want my old snow, mudder, slick tires, they will have to pry them off my cold dead wheels............

Okay, here's my PROFESSIONAL experience with EVs.

As some of you may know, I'm a parts manager for a Volvo/Polestar dealership. I see the bill for every tire we sell.

EV tires are not selling appreciably faster than ICE tires.

Yes, 15,000 to 20,000 is real. That's better than what you get out of many cars. Mercedes cars with similar performance spec tires won't make it 15,000 miles. Most AMGs are done around 12,000.

Yes, heavier vehicles wear tires quicker than lighter cars. BUT....

Drivers using their brakes to slow the cars at the last moment wear their tires quicker than more gradual brakers. Many EV drivers use regen braking (one pedal drive) and that prolongs both tire and brake life. It's a gentler braking cycle.

As for driving an EV, I drove a Polestar 2 Performance Pack car for a week. I was easily able to keep up with my daily consumption using a 110 charge cable. I work 12 miles from home, drive to lunch every day, and ran errands after work.
I specifically used the 110 to test worse case common use.

I think the range anxiety issues come from seeing the remaining range in numbers instead of a gas gauge display. Seeing a number changes your perception.

Is an EV for me?

No. I'll keep my 620 hp V12.

Is an EV for you?

That's for you to decide.

JCC fits into the "common sense is not so common anymore" category...

Are we still talking about Grandpa's off road over loaded coal trucks tire wear?

sample quote

Bridgestone’s Senior Product Manager Brad Robison says the company’s internal testing shows that EVs “go through a set of tires roughly 30-40 percent more quickly than their comparable ICE counterparts.” This is because of factors like EVs extra weight, power and torque. It doesn’t seem that they actually have a way to stop this from happening, but they hope they can slow it down. To combat premature wear, Robison says Bridgestone developed PeakLife. PeakLife is described as a polymer that can both extend tread life and “deliver lower levels of rolling resistance to help increase vehicle range.”

“We see a bonding rate with silica of roughly 50 percent compared with perhaps 20 percent on conventional polymers,” Robison said. You can find this tech on the company’s aforementioned Turanza EV tire.

Other tire manufacturers more or less said the same thing.

Pirelli said that there are a few things that make a tire EV-specific, like being made with different compounds for low rolling resistance and a quieter ride. They pointed me to the company’s P Zero All Season Plus with their Elect marking. They market tires with “Elect” as being specifically developed for “high performance electric and plug-in vehicles,” supposedly able to handle high torque loads and the extra weight of EVs.

Sometimes though it was hard to get someone to explain to me just what makes a tire EV specific. Michelin’s Technical Communications Director Russell Shepherd told me the brand currently sells one EV-specific tire in the U.S. in the Pilot Sport EV. Cool, but again, what makes them EV-specific? I got an around-the-way answer that really said nothing.

The Michelin Pilot Sport EV tire is a product specifically developed for OE high-performance EV fitments. This experience confirmed our understanding of the EV tire market: Consumers of EVs have similar needs to ICE tires, quite tire, efficient, traction and with performances that last.

You don’t actually have to have an EV tire for an EV. In fact, regular tires might be a better option for your EV as Tire Rack found in their testing of EV tires.

Not only can you use an ICE tire on an EV, in many cases, it may be a preferable option. EV tires have specific characteristics to carry the vehicle load and achieve the best possible range per charge, but in many cases, we’ve found the loss in range to be minor compared to ICE tires, and the potential advantages in other characteristics like wet braking or winter performance, to be worth the exchange.
