.07 Tires.

A. Tire Inspection — Steering Axle.

Procedures: Reject Vehicle If:
(1) Inspect for tire wear.
(a) Tires without tread wear indicators.
(b) Tires with tread wear indicators.
(1)
(a) Tire is worn so that less than 4/32 inch remains when measured in any two major grooves at three equally spaced intervals around circumference of a tire.
(b) Tread wear indicator contacts the road in any two adjacent major grooves at three equally spaced intervals around circumference of a tire.
(2) Inspect for tread cuts, snags, or sidewall cracks. (2) Tire has tread cuts, snags, or sidewall cracks in any direction and deep enough to expose cord fabric.
(3) Inspect for exposed cord fabric. (3) Tire has any part of the breaker strip or casing ply exposed in the tread.
(4) Inspect for bumps, bulges, or knots. (4) Tire has visible bump, bulge, or  knot related to tread or sidewall separation.
(5) Inspect for patching. (5) Tire has a boot, blowout patch, or other ply repair.
(6) Inspect for tire matching. (6) Bias ply and radial ply tires are mixed on same axle, or tires on same axle are not equivalent to size recommended by tire or vehicle manufacturer.
(7) Inspect for restricted usage. (7) Tire is labeled "Not for Highway Use" or other labeling which excludes use on a steering axle.
(8) Inspect for regrooved or recut tires. (8) Tire is regrooved or recut and regrooving or recutting is not permitted by tire manufacturer.
(9) Inspect for proper mounting. (9) Tire has tire flap protruding through valve stem slot in rim.
(10) Inspect valves and valve stems for leaks and mounting. (10) Valve stem leaks, is damaged due to misalignment, or is positioned to interfere with checking tire air pressure.
(11) Inspect for wheel and tire mounting. (11) Tire or wheel contacts vehicle chassis or body.
(12) Inspect for weight limit rating. (12) Gross vehicle axle weight exceeds tire load rating, which includes under-inflated tires.

B. Tire Inspection — Nonsteering Axle.

Procedures: Reject Vehicle If:
(1) Inspect for tire wear.
(a) Tires without tread indicators.
(b) Tires with tread wear indicators.
(1)
(a) Tire is worn so that less than 2/32 inch remains when measured in any two major grooves at three equally spaced intervals around circumference of a tire.
(b) Tread wear indicator contacts the road in any two adjacent major grooves at three equally spaced intervals around circumference of a tire.
(2) Inspect for tread cuts, snags, or sidewall cracks. (2) Tire has tread cuts, snags, or sidewall cracks in any direction and deep enough to expose cord fabric.
(3) Inspect for exposed cord fabric. (3) Tire has any part of the breaker strip or casing ply exposed in tread.
(4) Inspect for bumps, bulges, or knots. (4) Tire has visible bump, bulge, or knot related to tread or sidewall separation.
(5) Inspect for patching. (5) Tire has a boot, blowout patch, or other temporary ply repair.
(6) Inspect for tire matching. (6) Bias ply and radial ply tires are mixed on same axle, or tires on same axle are not equivalent to size recommended by tire or vehicle manufacturer.
(7) Inspect for restricted usage. (7) Tire is labeled "Not for Highway Use" or other labeling which excludes use on a highway vehicle.
(8) Inspect for regrooved or recut tires. (8) Tire is regrooved or recut and regrooving or recutting is not permitted by tire manufacturer, or vehicle is equipped with regrooved tires on the steering axle.
(9) Inspect for recapped or retreaded tires on front wheels. (9) Equipped with recapped or retreaded tires on the front wheels.
(10) Inspect for proper mounting. (10) Tire has tire flap protruding through valve stem slot in rim.
(11) Inspect valves and valve stems for leaks and mounting. (11) Valve stem leaks, is damaged due to misalignment, or is positioned to interfere with checking tire air pressure.
(12) Inspect for wheel and tire mounting. (12) Tire or wheel contacts vehicle chassis or body.
(13) Inspect for weight limit rating. (13) Gross vehicle axle weight exceeds tire load rating, which includes under-inflated tires.
(14) Inspect spare tire storage (if equipped). (14) A spare tire is not properly secured.
