Miami Herald has article about short life of E.V. tires

[PandaBear]

I have friends with track cars chewing up tires every 1-2 track days. If you put a track tire on a road car and run it like a track car it will get horrible tire life. The big torque of a heavy EV like Tesla with dual motors or plaid will need contact patch that's much stronger than a Prius driver hypermiling for 60mpg.

The other thing is the market for these tires are smaller than Camry or Corolla, so they are going to target their racing / track / drag race on the street customers and make those tires trade off for that size. Who would make and who would buy a 80k UTQG model 3 plaid size tire with no traction? They would buy the 20k UTQG tire of the same size with maximum traction instead.

It is not the weight, pickup truck and SUVs have no problem with tires. It is the way it is used and the torque.

500# just isn't killing tires, lol. Maybe a hair worse wear, but its not earthshattering.

I dont see where the EV9 model is listed, there are many different models of it. Including two "light" versions.
The publication is about speed in a SUV truck. I get that, it's really the only thing that can beat out the ICE, other than that, it cant offer anything else if someone wants a truck.

Not sure with the EV9 limits on towing and convieance of recharging, how much acceleration matters.
Durango tows 8,700 Lbs
All models of the EV9 tow a max of 5000 Lbs.

If you've ever owned a HEMI powered vehicle, then you know what an EV offers over it, lol!

The model in the article was the AWD GT Line model.

You mean a lower tow rating for the EV and short driving range for the EV and LONG recharging time vs filling with gas?

I guess if you tow a large boat or camping vehicle, you would know how much better the hemi is over the EV
But you don’t even need the hemi the regular tow rating for the smaller engine is still 40% more towing capacity over the EV

The EV is helpful if you wanted to drag race on a straight track with an SUV

I suppose one thing that could be done is that there be some sort of tire saving mode that reduces wheel slip. A ton of tire wear comes from burning rubber, as we can see tire marks left on almost any street or freeway. There's just so much control that can be done with an EV that's just not possible with an ICE and a transmission to decrease wheel slip.

Right now a lot of EVs are tuned for where I could see a lot of premature tire wear for anyone with a heavy foot. Howevever, I've heard of people getting 30-40K miles on their Tesla Model 3s. I noted a loaner that looked like it had 5 year old factory tires at about 50K miles. They were close to the wear bars though. I imagine that there weren't a lot of people driving the loaner really hard for fear of damaging it.

Chill mode does reduce the initial power hit. I personally still use the more aggressive setting and am just lighter on the throttle. I want the immediate hit on occasion and then I’m just more gentle with my inputs. I just wonder if the average driver doesn’t consider tire damage to avoid it or if that many people really want to fly around. Here I see burnout marks but most of the time you see it happen it’s hopped up trucks and performance cars, people intentionally doing it. I wouldn’t say the average person drives fast here, but I see just the opposite when I’m in big cities.

I guess it depends on what I needed to do. If I needed to take a boat 30 miles I’d have no problem doing that with an EV properly rated for it. 300-500 miles? Who’s got time for that?

Towing is for sure its weak point, but for a people hauler, $85 > $600 monthly fuel cost.

One guy on the ev6 forum gets like 75k miles per tire change. Has 156k mi on his car. Rwd and he is conservative with throttle.

It's got to be stupid people doing stupid tricks or really cheap tires.

What dawned on me when reading this thread. It’s as if we live in a world without 10th grade physics. Is the earth really devoid of this science, or have people simply chosen to ignore it, who knows anymore.

More like deny it.
