17 or 18 inchers will fit nicely with a good choice of tyres at sensible money.
VW, AUDI or Porsche 4x4 wheels with 5x130 PCD will be fine. There are many threads on tyres and wheels - look them up.
I strongly recommend Michelin Latitude Cross - excellent grip, quiet, comfortable and long lasting too. These are a good tyre to run year round on your Tdi.
You were misinformed on minimum wheel sizes elsewhere!
