It's not the weight. It's the torque.

[–] Ulrich@feddit.org 8 points 4 weeks ago

Pretty sure the weight has a significant impact on tire wear...

[–] NotJohnSmith@feddit.uk 3 points 4 weeks ago

Is there an argument that with regen in EVs there is a smoother transition in speed continuing to less wear to tyres/roads?

I certainly drive my EV more calmly than ICE due to the relaxed vibe of an EV

[–] bufalo1973@piefed.social 1 points 4 weeks ago (2 children)

And EVs don't have to change gear¹, so smoother driving and less wear.

¹ automatic also has gears.

[–] frongt@lemmy.zip 4 points 4 weeks ago

A lot of cars have CVTs. No changing gears on those.

[–] Ozymandias1688@feddit.org 1 points 4 weeks ago (1 children)

not necessarily. Toyota uses planetary gears which also change transmission without discrete "gear shifting". Although going fully EV removes that necessity of course.

[–] Ulrich@feddit.org 3 points 4 weeks ago (1 children)

Planetary gears have been used in automatic transmissions for as long as they have existed. I think you're thinking of CVTs.

[–] Ozymandias1688@feddit.org 2 points 4 weeks ago* (last edited 4 weeks ago) (1 children)

Yes, exactly! Thanks! EDIT: According to Wikipedia, the CVT in Toyotas is based on planetary gears, so both seems correct.

[–] Ulrich@feddit.org 1 points 3 weeks ago

I don't think you understand. Planetary gears have nothing to do with how the vehicle shifts.
