Another poster helpfully pointed out to me that the ID.4 has different tire/wheel sets front and rear, thus precluding ordinary tire rotation practices.
Specifically, from the specs buried in the bowels of VWs website:
Wheels :
20-in x 8J in front & 20-in x 9J in rear
Tires:
235/50 R20 104T XL in front 255/45 R20 105T XL in rear
The ID.4 is basically a rear-wheel drive vehicle. I would guess the AWD version, correct me if I'm wrong, will have a computer send power to the front motor as required for traction or power demands (the reverse of a Subaru or most other AWD cars).
I presume that the reason the rear tires are wider has to do the car's basic rear drive design.
(Haven't done the math, but I'd guess the actual sidewall heights are about the same.)
Still, I don't get it. Why would having slightly wider rear tires and wheels be worth disallowing wear saving tire rotations and the near certainty of having front and rear tires wear at different rates, possibly requiring annoying two-at-a-time tire replacements?
After all, we're not talking a monster power car here, like a Vette or a dragster or the like. This is a "family" car.
So what is the logic behind this set-up?
Are there any automotive engineers here who can 'splain?
