For those who live in the Chicago/Suburbs. What is your schedule for changing tires? When do you swap to Winter Tires and until when do you keep them on for? This will be my first time ever I will have a set of winter tires. I usually have all seasons. However, with a Model S, I'm not going to mess around. And do you use all season for summer or do you stick with "summer" tires for summer time?
