If the 19s are stock OEM wheels they are from an AWD R/T and will not fit your Scat Pack.
My recommendation is to get one of the 2-3 sets they sell on Tire Rack that are 18x8 and clear the 4 pot Brembos (unless you have 6 pot Brembos then you might be stuck with 20s).
There is usually 2-3 choices like Sport Edition KV5 (not the best looking but oh well). For Tires I'd recommend the Michelin XIce Snow in a 225/60/18. Don't be afraid of the smaller contact patch... that actually helps you in snow putting more lbs/sq inch for traction.
If you insist on another tire you can use 235/55/18 size too. I really love the Michelin XIce Xi3 (which was the immediate predecessor to the XIce Snow this year). The new Snow model was supposed to best the old Xi3. They have a real treadwear warranty and last a good 35-40k miles in my experience before you get closer to the snow wear bars and they start acting more like really good all seasons.
Since I have an R/T with base brakes I was able to buy some new old stock Mopar wheels from the c. 2011 Challenger Ralleye package:
