Yes. I've been using the same 15x6 steel wheels for my snowtires since my 2005 Prius. I know that for 2016 the stock 15" rims are 15x6.5, but the 15x6 seems to work fine. I currently have 185-65-15 tires on them which is about 2% smaller than the stock 15 or 17 inch tires for 2016, so my speedo reads about 2% low. The blizzaks are almost worn anyway so I'll replace them with the correct size tire, (195-65-15) soon.
This is what I'm using on third gen, believe 4th gen is the same: Corolla 15" black steel rims p/n: 42611-02471 With lug nuts p/n: 90942-01007
