Hahaha omg snow chains in new jersey, this post made my night. First off I would be more concerned about your car getting hung up on the snow rather than not getting enough grip. I have run through A LOT of snow with my camaro with snow tires.
If you are really afraid of snowmageddon that route I might suggest textile snow chains. I discovered these when buying parts for my old bmw.
