Hate to tell you this, but no one in Minnesota uses tires chains anymore - they are illegal on our roads. But it is crucial to have a good battery and good snow tires help. Mayo Clinic is in Rochester, MN and frequently Rochester has big snows.

We in Minnesota when traveling have emergency food, blankets, etc. in the car. Jumper cables are in most of our car trunks just in case our battery gets weak and won't start the car. At least one can get to someplace to get the battery charged or buy a new one.

If caught in a bad snowstorm stick with the car - do not try to go for help during a snowstorm here! The weather reports here are excellent and it is best to know what is being forecast for any trip that is planned.
