§1917. Tires and wheels
................
2. Safe tires required. A motor vehicle may not be operated on a public way unless it is equipped with tires in safe operating condition. A tire mounted on a motor vehicle is not considered to be in safe operating condition unless it meets the visual and tread depth requirements set forth in subsections 3 and 4, the overall diameter of the properly mounted and inflated tire is within 2 inches of the range of sizes recommended by the manufacturer for the model vehicle and the vehicle is in compliance with the frame height requirements provided in section 1920.
[ 2009, c. 251, §8 (AMD) .]
3. Visual requirements. A tire is not in safe operating condition if that tire has:
A. A fabric break or a cut in excess of one inch in any direction as measured on the outside of the tire and deep enough to reach the body cords; [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
B. A temporary repair by the use of blowout patches or boots; [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
C. A bump, bulge or knot related to separation or partial failure of the tire structure; [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
D. A portion of the ply or cord structure exposed; or [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
E. Sidewalls damaged to the extent that the body cords are damaged. [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
[ 1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF) .]
4. Tread depth. A tire is not in safe operating condition if it is worn to the point where less than 2/32 inch of tread design remains at all points at which gauge readings are required. Tread depth must be measured as follows.
A. Tire tread depth must be measured by a tread depth gauge that is calibrated in 1/32 inch. [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
B. Readings must be taken in all major tread grooves and must include at least 2 points not closer than 15 inches. [2007, c. 348, §17 (AMD).]
C. Readings for a tire that has the tread design running across the tire or for a siped tire must be taken at or near the center of the tire at 2 points of the circumference not closer than 15 inches. [1993, c. 683, Pt. A, §2 (NEW); 1993, c. 683, Pt. B, §5 (AFF).]
