When spring time rolls around sell your 205/55/16 summer tires and purchase a set of new/used 18 or 19 rims along with summer tires. Actually you can start looking at your summer set during the winter season, I am sure you can get a better price during the off season.
Second this option... I would look during the winter for a set of summers... just because around January people sell off a whole bunch of things to pay the Christmas debt off...
