EV thread

A Rivian YouTube video popped up in my feed. Video claimed used ones were in the low 30s. I watched the video and was surprised by the tire cost.

And the fun part is that tires on EVs don't last long at all!
 
How many miles? What is he doing to burn so many tires, or is it just part of the weight penalty?

He bought a replacement set of 21" tires , then a set of 20" wheels and snow tires , and a set of 20" street tires .
The " pickup " is pig heavy and weights 7300 lbs. empty , and we live in the mountains with steep grades and lots of curves . He only has 14,000 miles on it.
The weird 21" EV spec tires cost over $ 700 each.

The " cost per mile " number would be high when you figure $97,000 purchase price and tires.

How does an EV spec tire differ form a regular tire?
 
Not really just the way the electric engines deliver torque

That doesn't make sense. If that was the specific cause of rapid tire wear, then modern diesel trucks would be experiencing similar issues, seeing as most of them are hammering out 700+ lbs/ft of torque right off idle and quickly heading to 1,000lbs/ft+.

I think it's more likely that these EVs are trying to run tires too soft, too small, and not at their weight requirements.

There's also the option that it just takes that much effort to move smug douchebags around. :sneaky:

I did find this torque graph in an older Tesla article. It's interesting, but misleading.

Lower rolling resistance , yet strong enough to deal with a 7300 lb. vehicle.

I'm not fully educated on it but I've read that EV specific tires are built with stiffer sidewalls and acoustic dampening materials like foams inside the tires.

Without knowing or digging very deep, I'm guessing the manufacturers are utilizing the lightest load rated tires to provide a soft feel for these passenger vehicles. They're probably hemmed in between passenger comfort demands and physical size limitations considering how big the brakes and wheels have to be, yet how small the tires need to be for the vehicle. A 33" tall tire on a Model 3 probably won't work for most people.
