You are spot on Tuareg, to hear somebody say regen braking has minimal effect, it definitely has a direct effect, if your body can feel the deceleration as with regen left on the default 'high' setting, it definitely will have a considerable impact.
I reckon the important order of wear is.
1. Rapid acceleration, but predominantly on the drive axle.
2. Hard cornering, especially roundabouts will affect all tyre wear.
3.Hard braking, will affect all tyres.
4. Regenerative braking, wiil only affect the drive axle, my Trophy LR, is wearing poorly, especially the rear (drive axle) I may make 11000 miles if I'm careful.
Probably missed something
I knew all EV's are heavy on tyre wear, but I wasn't expecting it to be this poor.
My guess is it's the cheap crap tyres fitted from new, that said it's a great inexpensive car.
