Va. Code § 46.2-1044
No tire on a vehicle moved on a highway shall have on its periphery any block, stud, flange, cleat, spike, or any other protuberance of any material other than rubber which projects beyond the tread of the traction surface of the tire. It shall be permissible, however, to use on the highways farm machinery having protuberances which will not injure the highway and to use tire chains of reasonable proportions when required for safety because of snow, ice, or other conditions tending to cause a vehicle to slide or skid. It shall also be permissible to use on any vehicle whose gross weight does not exceed 10,000 pounds tires with studs which project no more than one-sixteenth of an inch beyond the tread of the traction surface of the tire when compressed if the studs cover no more than three percent of the traction surface of the tire.
The use of studded tires shall be permissible only from October 15 to April 15.
The provisions of this section shall not apply to any (i) law-enforcement vehicle operated by or under the direction of a federal, state, or local law-enforcement officer; (ii) vehicle used to fight fire, including publicly owned state forest warden vehicles; (iii) emergency medical services vehicle; or (iv) vehicle owned or operated by the Virginia Department of Transportation or its contractors in maintenance and emergency response operations.
