Indiana Tire Regulations

When required for safety because of snow, ice or other conditions, tire chains of reasonable proportions may be used on the highways. From October 1 to May 1, tires in which ice grips or tire studs of wear-resisting materials have been inserted may be used.

Metal tires

A solid tire made of rubber on a vehicle must have rubber on the tire's entire traction surface at least one (1) inch thick above the edge of the flange of the entire periphery. A person may not operate or move on a highway a motor vehicle, trailer, or semitrailer having a metal tire in contact with the roadway.

Protuberances on tires

(a) Except as provided in subsections (b) through (e), a tire on a vehicle moved on a highway may not have on the tire's periphery a block, stud, flange, cleat, or spike or any other protuberance of any material other than rubber that projects beyond the tread of the traction surface of the tire.
(b) Implements of agriculture may use tires having protuberances that will not injure the highway.
(c) Tire chains of reasonable proportions may be used upon a vehicle when required for safety because of snow, ice, or other conditions tending to cause a vehicle to skid.
(d) From October 1 to the following May 1, a vehicle may use tires in which have been inserted ice grips or tire studs, including retractable tire studs, that:
(1) are of wear-resisting material;
(2) are installed in a manner that provides resiliency upon contact with the road;
(3) have projections that do not exceed three thirty-seconds (3/32) of an inch beyond the tread of the traction surface of the tire; and
(4) are constructed to prevent any appreciable damage to the road surface.
(e) Notwithstanding subsection (d), a vehicle may be equipped year-round with tires that have retractable tire studs if the tire studs remain retracted from May 2 to September 30 of each year.
