Final answer:
In New Jersey, studded snow tires are permitted for use from November 15 to April 1 to ensure safe driving during winter conditions.
Step-by-step explanation:
In New Jersey, studded snow tires can legally be used from November 15 to April 1. This is to accommodate for winter weather conditions where the extra traction provided by studs can be beneficial for safe driving on ice and snow-covered roads. Studded tires are specifically designed for these conditions and using them outside the specified dates can cause excessive wear on dry pavement and can be illegal.
