Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
This is not a problem at all, as long as they're original Porsche wheels, and tires
as they will have the correct overall rolling diameter, which will match what you already have
If you're looking to go with a custom, non-porsche setup, then sizes, offsets, and bolt pattern are critical
here are recommended sizesOffset: 51mmBackspacing: 6.81"Bolt Pattern: 5-130Rec. Tire Size:235/35-19
for the front
And for the rear:Offset: 56mmBackspacing: 8.19"Bolt Pattern: 5-130Rec. Tire Size:265/35-19
