slightly different size for rear tyres than factory spec possible?

[TaYcanAficionado]

I have 21' taycan exclusive summers on my 2021 4s and, since winters are not that harsh in my country, I am thinking of going with a second set using 19' rims for the winter period with all season tyres. I prefer 19' over 20' to maybe win a bit of range - which we lose anyway because of the winter temps. Mine doesn't have the PCCB brakes so 19' rims can fit.
Rear tyres factory spec for 19' rims is 275/45r19, which is close to inexistent in Europe for all-seasons (only options for summer/winter tyres available). On the other hand, I can find premium all seasons with very good reviews in the 285/45r19 size. Front tyres are not an issue - easy to find all season for the factory spec.
It seems that 285/45r19 is very close in diameter and overall size (https://www.calculator.net/tire-siz...5&car2=45&cws2=19&ctype=2&x=Calculate#compare)

Do you think it's doable? Any thoughts?

I would buy 19' for the second set (all season ). Factory spec of course. my summers are 21'

Haven't bought it yet... But I'll definitely go with the factory spec 19 rim, meaning
19 inches - 10.0 J, ET 47.0, 5/130

Thanks - my experience from other cars is that as long as you lie within a 3% in tyre size difference you are fine in 99% of the cases. No problems with the Esp nor braking etc. Just wanted to make sure that 285/45r19 isn't a "no-go" for any not-so-obvious reason on the taycan. Pity there aren't any all season options for the factory spec 275/45r19 in Europe....
Would prefer to go 19' instead of 20' for the all season, to win some range in the winter period...there are B class energy efficient tyres in Europe for 285/45r19, like the Michelin crossclimate2 which has a lot of positive reviews

During my visit to the Taycan factory tour, I was surprised to see a significant number of cars leaving the production line with 19-inch wheels fitted. I had assumed that this would be rare, but it seemed that most rear-wheel-drive Taycans on the day I visited had 19-inch wheels, with Hankook iON NF0 tyres being particularly popular.

Doesn't make any difference.
The front and rear motor aren't physically connected to each other.
With ICE 4WD car that's a real issue (outside tolerance that is), not with electric cars.
Inverters/motors are torque-driven and not speed-driven.
