Are studded tires legal in Louisiana?

Louisiana law bars studded tires, with narrow exceptions. Louisiana bars any tire with a protuberance of material other than rubber that sticks out beyond the tread, which rules out metal tire studs on the highway at any time of year. La. R.S. 32:362 reads: "B. No tire on a vehicle moved on a highway shall have on its periphery any protuberances of any material, other than rubber, which projects beyond the thread of the traction surface of the tire"

Louisiana sets no studded tire season. The statute's exceptions: Farm machinery may use tires with protuberances that will not injure the highways. The department may give emergency permission for tracked traction engines, farm tractors and other farm machinery.

Tire chains of reasonable size may be used on any vehicle when conditions make it likely to slide or skid. The statute reads: "(2) Use tire chains of reasonable proportions upon any vehicle, when required for safety because of conditions tending to cause a vehicle to slide or skid."
