The rubbing with a tire with a greater volume than 25 mm or 26 mm, is that happening with the 622 x 15C wheel?

You should not have expected the above to work. Either a wider wheel or a wider tire alone increases tire volume, both together would have increased tire volume by even more. Probably the best you can hope for is a 25 mm tire on a 622 x 17C wheel.
