257.710 Tires; studs or other traction devices; rules; exceptions; use or sale of unsafe tires
prohibited.
Sec. 710. (a) A person shall not operate on a public highway of this state a vehicle or special mobile
equipment which has metal or plastic track or a tire which is equipped with metal that comes in contact with
the surface of the road or which has a partial contact of metal or plastic with the surface of the road, except as
provided in subsections (c), (d), and (e).
(b) A person shall not operate on a highway a vehicle which has a tire that has on its periphery a block,
stud, flange, cleat, spike, or other protuberance of a material other than rubber which projects beyond the
tread of the traction surface of the tire, except as provided in subsections (c), (d), and (e). A person may,
however, use farm machinery with a tire having a protuberance which will not injure a highway. A person
may also use a tire chain of reasonable proportion upon a vehicle when required for safety because of snow,
ice, or other condition tending to cause a vehicle to skid.
(c) A person may operate on a highway a vehicle which has a pneumatic tire in which wire of .075 inches
in diameter or less is embedded if the tire is constructed so that the percent of metal in contact with the
highway does not exceed 5% of the total tire area in contact with the roadway, except that during the first
1,000 miles of use or operation of the tire the metal in contact with the highway shall not exceed 20% of the
area.
(d) The department of state highways and transportation shall promulgate rules establishing acceptable
standards to permit the use of a tire with studs or other traction devices to be used on a street or highway after
April 1, 1975. The rules shall make separate provision for the extreme winter snow and ice conditions of the
Upper Peninsula and the northern Lower Peninsula. The rules shall include a restriction on the amount and
dimension of protrusions that may be allowed on a tire, the type of material that may be used in a stud,
traction device, or tire, and the amount of road wear that a tire with studs or other traction devices may cause
on a street or highway.
(e) A person may operate on a highway a vehicle which has a pneumatic tire in which are inserted ice grips
or tire studs if the person is a law enforcement officer operating a vehicle owned by a law enforcement
agency, a person operating an ambulance, or a United States postal service rural carrier driving a vehicle the
rural carrier owns and maintains as a prerequisite to employment in the postal service.

provided in subsection (h).
