Best tires and wheel size to quiet road noise?
I would go with the original specified tires for the car and choose a highly recommended tire like Continental, Michelin or something similar. Remember, the problem with Michelin tires is they make a lot of different grades in different price points. Select one of their better grades; the devil is in the details. Some people think that Continental tires are not very good, they are mistaken.

Link wouldn't function, perhaps too old. Why not switch to 17" wheel, same as on the 2.5 version of car?
Try the link I just posted. Why are you looking to replace these tires so quickly? It's a 2015 model? Check your owner's manual.
