I just bought a 2014 with sport package and will be driving in the winter as well, but I won't be daily driving it (I take the train to work every day) so I can choose when I want to take her out.
No TPMS
I personally went with these rims in 18x8
DAI Alloys Razor
And for tires I went with Michelin X-ice Xi3. Reason being they are supposedly excellent on ice (we get alot in Montreal) and dry roads, but not very good in 5+ inches of snow. Don't really care since the car probably won't clear 5 inch of snow anyway and i'd just be plowing the roads, so I'll just wait for the real snow plows to do the work.
