Its spring now, so you've probably already done what ya need to do, but I just discovered this board... But if you're still looking, I've been running Scorpion winter 295/45 R 20s on my '15 SRT and its unstoppable in snow. I'm about to trade that in for a new TH and I'll definitely be getting the 3 season scorpions and switch em out again come December. You can buy em from Bar in Chicago!
