Studded snow tires are still legal in New Jersey between November 15 and April 1. I used to run studded snows in the bad ol' days when I needed to get out of bed before the salt truck drivers.
The racket drove me crazy and my wife said she could hear my car from blocks away. The car's handling on dry pavement was atrocious.
But they were fantastic on ice!
