How so? And does that mean the rims would actually take a wider tyre......?
Looking at your picture, you seem to have the wheels with part number 4E0 601 025 BD.

This wheel has an ETR of 45 and is 9J x 20H. In the Audi Wheel and Tyre Guide, there are 6 '9J x20H' wheels; 4 have ETR of 46 and 2 have ETR of 45. [ETR is the hub offset].

Audi tyre sizes for them are:
9J x 20H - ETR 46 - 275/35 R20
9J x 20H - ETR 45 - 265/35 R20

Presumably to allow for prevention of 'rub against the arch' for the ETR 45s
