P400e downsizing to 20". Suspension calibration? Pressu

Hello everybody! Surely 21s look good, but I need a bigger sidewall for the place where I live. So I decided to go to the smallest possible for p400e wheels - 255.55.20 Scorpion Zero AS LR PNCS

Can someone please advice though... Back in the l322 td6 days I remember changing rims size required air suspension calibration. Will I have to do it in l405?

Another question relates to the pressure. Sticker on the door says 2.3 front & 2.5 rear for 255.55.20, but TMPS system in the car when set to light load expects (2.4) front and 2.8 rear, so something does not match well...

Would appreciate your responses!

Stop worrying, just drive the thing.

A slight change in wheel/tyre size isn't going to be an issue, and 4 psi change in tyre pressure is nothing to worry about 👍

Gotcha, thanks! And yup, forgot to mention I'm rolling on 275.45.21 now. Online calc says its within acceptable values.
