Rims to fit RS4 B8

[FatDumbHappy]

Hi,

I'm very new to this, so I apologize if this question has been breached before.
I have a 2014 RS4 B8, which I love (dream car). I'm moving to a country where the roads are slightly worse and taking the car with.
I'm thinking of changing FROM the 20" rims running 265/30 TO 19" 255/40.
I'm needing the slightly extra profile on the tyre. I know the 20" look the business, so it's a shame to have to try look for 19"rims.

I'd really appreciate if anyone give me some advice on IF 19" rims can fit, and if so which ones?

Kind regards
FDH
