Current through Register Vol. 48, No. 28, July 12, 2024
a) TIRES
1) Tires on Any Steering Axle of a Power Unit
PROCEDURES/SPECIFICATIONS:
All tires on any steering axle of a power unit must
				be in good condition and used correctly. There must be at least 4/32 inch tread
				depth without any mixing of tire construction on the same axle. Buses must not
				be equipped with recapped or retreaded tires on any steering axle.
The following procedures apply only to tires found
				on any steering axle of a power unit:
Measure the tread depth at any point on a major
				tread groove for at least 4/32 inch tread.
Inspect tread or sidewall for exposed body ply or
				belt material.
Inspect tread or sidewall for separation.
Inspect tire for cuts that expose ply or belt
				material.
Inspect tire for the label "Not For Highway Use" or
				any other marking that would exclude its use on a steering axle.
Inspect tire to determine if it is a "tube-type
				radial". If it is, it must have "radial tube stem" markings. These markings
				include a red band around the tube stem, the word "radial" embossed in metal
				stems, or the word "radial" molded in rubber stems.
Inspect for any mixing of bias and radial tires on
				the same axle.
Inspect for tire flap that protrudes through the
				valve slot in rim and touches the stem.
Inspect for regrooved tires.
Inspect tire for boot, blowout patch or other ply
				repair.
Inspect tire load limit to determine if weight
				carried exceeds limit. This includes overloaded tire resulting from low air
				pressure.
Inspect tire for flat condition or noticeable leak
				(i.e., can be heard or felt).
Inspect buses for recapped or retreaded tires on
				steering axle.
Inspect tires to determine if they are so mounted or
				inflated that they come in contact with any part of the vehicle.
REJECT VEHICLE IF:
The following criteria apply only to tires found on
				any steering axle of a power unit:
Any tire with less than 4/32 inch tread when
				measured at any point on a major tread groove.

				through the tread or sidewall.
Any tire that has any tread or sidewall
				separation.
Any tire that has a cut where the ply or belt
				material is exposed.
Any tire that is labeled "Not for Highway Use" or
				displaying other marking which would exclude its use on a steering axle.
Any tire with a tube-type radial tire without radial
				tube stem markings. These markings include a red band around the tube stem, the
				word "radial" embossed in metal stems, or the word "radial" molded in rubber
				stems.
Any tire has bias and radial tires mixed on the same
				axle.
Any tire where the tire flap protrudes through the
				valve slot in the rim and touches the stems.

				repair.
Any tire in which the weight carried exceeds tire
				load limit. This includes overloaded tires resulting from low air
				pressure.
Any tire that is flat or has a noticeable leak
				(i.e., can be heard or felt).
Any tire on the steering axle of a bus that is
				recapped or retreaded.

				axle of a power unit must have at least 2/32 inch tread depth, be in good
				condition and be used correctly.
The following procedures apply to all tires other
				than those found on the steering axle of a power unit:

				carried exceeds limit. This includes overloaded tire resulting from low air
				pressure or tires of unequal size on the same side of the axle.

				(i.e., can be heard or felt).
Inspect tread or sidewall for exposed body ply or
				belt material.
Inspect tread or sidewall for separation.
Inspect tire for cuts that expose ply or belt
				material.

				inflated that they come in contact with any part of the vehicle, including a
				tire that contacts its mate.
Inspect tire for the marking "Not For Highway Use"
				or other marking having like meaning.
Measure tread depth at any point on a major tread
				groove for at least 2/32 inch tread.
REJECT VEHICLE IF:
The following criteria applies to all tires other
				than those found on the steering axle of a power unit:
Any tire in which the weight carried exceeds tire
				load limit. This includes overloaded tires resulting from low air pressure or
				tires of unequal size on the same side of the axle.
Any tire that is flat or has a noticeable leak
				(i.e., can be heard or felt).
Any tire that has body ply or belt material exposed
				through the tread of sidewall.
Any tire that has tread or sidewall
				separation.

				material is exposed.
Any tire that is so mounted or inflated that it
				comes in contact with any part of the vehicle, including any tire that contacts
				its mate.
