§ 11.60.270. Tires.

(a)

Every solid rubber tire on a vehicle shall have rubber on its entire traction surface at least one inch thick above the edge of the flange of the entire periphery.

(b)

No person shall operate or move on any highway any motor vehicle, trailer or semitrailer having any metal tire in contact with the roadway.

(c)

No tire on a vehicle moved on a highway shall have on its periphery any block, stud, flange, cleat or spike or any other protuberances of any material other than rubber which projects beyond the tread of the traction surface of the tire, except that it shall be permissible to use farm machinery with tires having protuberances which will not injure the highway, and except that it shall be permissible to use tire chains of reasonable proportions upon any vehicle when required for safety because of snow, ice or other conditions tending to cause a vehicle to skid, and except that the State Highway Commission is authorized to approve tires with metallic or nonmetallic studs which will not injure the highway and to issue and enforce regulations establishing standards and specifications for the approval of such studs.

(d)

The city manager may, in his discretion, issue special permits authorizing the operation upon a highway of traction engines or tractors having movable tracks with transverse corrugations upon the periphery of such movable tracks or farm tractors or other farm machinery, the operation of which upon a highway would otherwise be prohibited under this chapter.

(e)

It is unlawful for any person to operate a motor vehicle having one or more tires in an unsafe condition. A solid rubber tire shall be deemed to be in an unsafe condition if it does not comply with the provisions of subsection (a) of this section. A pneumatic tire shall be deemed to be in an unsafe condition if it has:

(1)

Any part of the ply or cord exposed;

(2)

Any bump, bulge or separation;

(3)

A tread design depth of less than one-sixteenth of an inch measured in any two or more adjacent tread grooves, exclusive of tie bars, or for those tires with tread wear indicators worn to the level of the tread wear indicators in any two tread grooves;

(4)

A marking "not for highway use" or "for racing purposes only" or "unsafe for highway use";

(5)

Tread or sidewall cracks, cuts or snags deep enough to expose the body cord;

(6)

Been regrooved or recut below the original tread design depth, excepting special taxi tires which have extra undertread rubber and are identified as such; or

(7)

Such other conditions as may be reasonably demonstrated to render it unsafe.

(f)

A person in the business of selling tires shall not sell or offer for sale for highway use any tire which is in an unsafe condition or which has a tread depth of less than two thirty-seconds inch measured as specified in subsection (e) of this section.
