This annual topic has been discussed before ad nauseum.
Answer 1: My Z doesn't even go outside unless it's over 70F, cloudless skies, and all the streets along the route have previously been street-cleaned in the last 2 days. On any day that doesn't meet these criteria, I ride a bicycle or stay home.
Answer 2: On days with any wintery precipitation, I instead drive a junkyard-salvaged SUV with bald tires that I've somehow rationalized is safer than driving the Z with snow tires.
Answer 3: I equip my Z with tank treads and routinely drive it into the Himalayas as I've found it handles better in snow than an M1A1 tank.
