The majority of states regulate when residents can use studded tires, generally limiting their use to the winter months. The most common regulation allows for studded tire use from October and November through March and April to help combat treacherous road conditions. Other states base their regulations on the size of the studs or type of vehicle used. For example, South Carolina allows studs less than 1/16th of an inch, while North Dakota and South Dakota allow studs on municipal vehicles, such as mail trucks, school buses and plow trucks.

Some states have no restrictions on the use of studded tires at all. Colorado, Kentucky, New Hampshire, New Mexico, North Carolina and Vermont are the only states that allow studded tires with no stipulations. Other states, such as Alaska, Alabama, Florida and Louisiana, allow studs made out of rubber materials so they do not cause any damage to roads and highways.
