§438.APPENDIX E. Tires through Wiring System

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.

 

Any tire that has body ply or belt material exposed 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.

 

Any tire that has been regrooved on the steering axle.

 

Any tire with a boot, blowout patch or other ply 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.

 

Any tire that is so mounted or inflated that it comes in contact with any part of the vehicle.

 

2)         All Tires Other Than Those Found on the Steering Axle of a Power Unit

 

PROCEDURES/SPECIFICATIONS:

 

All tires other than those found on the steering 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:

 

Inspect tire load limit to determine if weight carried exceeds limit.  This includes overloaded tire resulting from low air pressure or tires of unequal size on the same side of the axle.

 

Inspect tire for flat condition or noticeable leak (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.

 

Inspect tires to determine if they are so mounted or 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.

 

Any tire that has a cut where the ply or belt 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.

 

Any tire is marked "Not For Highway Use" or has other markings with like meaning.

 

Any tire with less than 2/32 inch tread when measured at any point on a major tread groove.
