No tire on any vehicle on any city highway shall have on its
periphery any block, stud, flange, cleat, ridge, bead or other protuberance
of metal or wood projecting beyond the tread of the traction surface
of the tire. The tracks of a crawler-type vehicle shall be considered
a tire within the meaning of this chapter.
(Prior code § 70.30)
The foregoing section shall not apply to:
A. The
use of tire chains of reasonable size to prevent skidding on surfaces
or on snow or ice;
B. The
use of pneumatic tires which have embedded in them wire not to exceed
0.075 inches in diameter and which are so constructed that under no
conditions will the percentage of metal in contact with the roadway
exceed five percent of the total tire area in contact with the roadway;
but during the first 1,000 miles of use or operation of these tires
the metal in contact with the roadway may exceed five percent of this
area, but shall in no event exceed 20% of the area;
C. Vehicles
operated on unimproved roadways when necessary in the construction
or repair of highways;
D. Traction
engines or tractors when operated under the conditions of a permit
first obtained from the public works director;
E. Pneumatic
tires containing metal-type studs of tungsten carbide or other suitable
material that are so inserted or constructed that under no conditions
will the number of studs or the percentage of metal in contact with
the roadway exceed three percent of the total tire area in contact
with the roadway, between November 1st and April 30th of each year.
The commissioner, after consultation with the Department of Transportation,
may extend the period during which studded pneumatic tires may be
used in any area of the state for the protection of the public because
of adverse weather conditions;
F. Pneumatic tires used on an authorized emergency vehicle, as defined in California
Vehicle Code Section 165, containing metal-type studs of tungsten carbide or other suitable material if the studs are so inserted or constructed that under no conditions will the number of studs or the percentage of metal in contact with the roadway exceed three percent of the total tire area in contact with the roadway. Notwithstanding subsection
E of this section, authorized emergency vehicles are permitted the unrestricted use of studded pneumatic tires throughout the year.
(Prior code § 70.31; Ord. 01-191 § 9)
No equipment attached to any vehicle such as discs, harrows,
scarifiers or other implements of agriculture or construction that
may scratch, cut, gouge, or otherwise mark a pavement, shall be allowed
to come in contact with any city highway; but the public works director
may permit the use of such equipment on a city highway on the filing
of an application for a permit, which he or she may issue with the
imposition of reasonable conditions that may be required to protect
the city highway.
