C43 normal tires sizes 225/40/19 and 255/35/19
If you now take 225/35/20 and 265/30/20, that is also good for the F / R ratio 4 matic.
Can you also take 235/35/20 and 265/30/20? can't you have any problems with that?

Tire size calculator apps or websites always recommend being within 3% of F/R tire diameter ratio. So, for as long as it’s within that range and still fits, it should be ok.
All those sizes you mentioned are within 3%, btw.
