Yes. You need to replicate the ZTK tyre sizing.
245/35/19 front and 255/35/19 rear - this is a 1.06% difference in rolling circumference, which technically is above the 1% that BMW apparently advise.
However, if you can, go for Michelin Pilot Sport 4S* which has some of the Cup2 compound - see link

The key point of using the star rated BMW homologated tyre is that if you dig deep enough, you will allegedly find that the rolling circumference of the star marked tyre is very slightly different to the non star rated tyre, which brings the rolling radius within the 1%. Can't verify this myself, but if BMW specify it as OEM, you can't go far wrong.
Hope this helps.
