With more "go" capability, you have more chance to be going faster than you should in icy conditions. Most of the cars I see off the side of a highway in a snow storm are 4wd/SUVs. Too many people don't have good sense. You're an experienced driver, so if you're fine with your car's rear end coming around on a curve, okay. Just don't kill anyone else. You did fine for 50 years without snow tires but have a new found liking of snow because you have front drive traction with decent tires up front. Do you have 50 years of experience driving with unbalanced traction?
