Tire Condition Awareness Program

2

In the following pages you will learn about tires and why tires fail. Recognizing tire condition and failures can avoid down time, Road Service

Calls, and can Reduce cost Associated with tire issues.

The condition of equipment at interchange is important. Interchange of equipment with a

railroad is governed by American Association of Railroads (AAR) TOFC/COFC Interchange Rules. Interchange of equipment with a steamship line is governed by IICL rules, as well as rules agreed upon between the trucker and the Equipment provider.

Suggested Motor Carrier actions are also provided. These recommendations are important because a Motor Carrier can save money and time, and protect himself by following these recommendations. Always have a tire replaced at the terminal instead of suffering the lost time and increased cost of having the tire replaced while on the road. Also please note that even if a tire condition is noted on the interchange inspection, if a Motor Carrier abuses the tire while on the road (turning a separated cap into a run flat by not stopping promptly for example), the responsibility becomes that of the Motor Carrier.

The intermodal industry has acquired thousands of new pieces of equipment equipped with radial tires and pressure maintenance systems, but still widely uses 10.00 X 20 bias ply tube type tires. Running any tire on low air pressure, with excessively weathered or dry rotted sidewalls, or with channel cracks will raise the risk of failure.

Recognizing tire issues will save down time and Service Calls

Damage to Mark on J-1

• It’s recommended to Mark this condition on J- 1 to avoid possible Re-bill issue.

• Unless cut is through to the cords and cords are showing, tire is considered road worthy.

• Cut in Sidewall• Why made = 14

Damage to Mark on J1

• It’s recommended to Mark this condition on J- 1 to avoid possible Re-bill issue.

• Unless cut is through to the cords and cords are showing, tire is considered road worthy.

• Cut in sidewall• Why made = 14

6

Damage

• This tire is cut - torn• Have this tire replaced

before leaving the Intermodal Facility.

• Cut – Torn Tire• Why made = 14

7

Damage

• Skid flat tires are considered Damage.

• Have this tire replaced before leaving the Intermodal Facility.

• The tread depth of the tire should be taken in three different places on the tire to obtain an average tread depth. If the difference between the average tread depth and the skid spot is 4/32nds or greater this tire should be replaced.

• Skid Flat Tire• Why made = 34

8

Damage

• It is possible to have one skid flat tire on one axle.

• AAR rules do not allow replacement due to mismatched tire heights

• A new tire or new recap could have been placed next to a worn tire causing this condition.


• Skid Flat Tires• Why made = 34

9

Damage

• Run Flat Tire• Why made = 13

• Replace tire before leaving Intermodal Facility.

The heat from a run flat is better seen on the inside! Rubber melted onto the rim

10

Damage

• Discoloration is a good indication of being run flat.



11

Damage• This is obvious, but both of

these tires need to be replaced before leaving the Intermodal Facility


12

Normal Wear and Tear

• Tires under inflated beyond 20% of the normal spec’, is considered FLAT by (OSHA).

• Example: If normal inflation is 100 PSI and tire is at 79 PSI or less, the tire should be broken down and repaired.

• Have this repaired or replaced before leaving the Intermodal Facility

• SEE CHART ON NEXT SLIDE FOR YOUR FLEET’S PSI SPECIFICATION.

• Flat Tires• Why made = 16

13

Fleet PSI Specification

• If a tire is less than 20% under inflated the tire should be aired up to the fleet spec’ and returned to service.

• If a tire is under inflated beyond 20% - The tire should be broke down and repaired before returning to service.

• See AAR Rule 99 decal on unit for fleet spec’s

Fleet Spec' 20 Percent Considered as

PSI Flat tire PSI

100 80 7995 76 7590 72 7185 68 67

14


• DOT requirements state. Tires must have 2/32” of tread or more to be street legal.

• Only tires with less than 2/32” of tread need to be replaced

• Have this tire replaced before leaving Intermodal Facility.

• Worn out Tire• Why made = 09

15


• AAR Rules call for weather checking not to exceed 1/32” deep.

• This condition could weaken the tire. Weight, speed or impact could cause this tire to fail


• Deteriorated Casing• Why made = 17

16


• AAR Rules call for weather checking not to exceed 1/32” deep.




17


• Deteriorated casing• Why made = 17 • This condition could

weaken the tire. Weight, speed or impact could cause this tire to fail.


18


• Channel cracks.




19


• Channel cracks.

• This condition weakens tires, and with speed and weight, or impact the tire could fail.



20


• Channel cracks.

• This condition weakens tires, and with speed and weight, or impact the tire could fail.


• Deteriorated casing• Why made = 17

21


• This cap is separating.• With weight and speed

it’s probable this condition will cause a tire failure.


• Separated Cap• Why made = 10

22


• This tire should be replaced before leaving the Intermodal Facility.

• Separated Cap• Why made = 10

23


• This cap is separating.


• Separated cap• Why made = 10

24

PSI Information

• This unit is equipped with an automatic tire inflation system.

• Tires will be airedautomatically when air is applied to the glad hands.

• Equipped with PSI

25

PSI Information

• Correct application of feed hoses.

• Incorrect application of feed hoses.

Disconnected or missing feed hoses should be repaired or replaced before leaving the

Intermodal Facility

Feed hoses should be connected at both ends.
