You don't need to put the snow tires on till there's actual snow on the ground and I've personally never used them. Also if you can avoid it don't drive during the first winter storm of the season as everyone seems to forget how to drive in wintery conditions during the summer

Invest in a good warm set of winter gear to include: coat, hat/ear muffs, gloves/mittens, and snow boots and it wouldn't hurt to keep a blanket in your car
