Tires, Wheels and Loading Note: Some spare tires operate at a higher inflation pressure than the other tires. For T-type/mini-spare tires (see the Dissimilar spare tire/wheel information section for description): Store and maintain at 60 psi (4.15 bar). For Full Size and Dissimilar spare tires (see the Dissimilar spare tire/wheel information section for description): Store and maintain at the higher of the front and rear inflation pressure as shown on the Tire Label. 6. Visually inspect the tires to make sure there are no nails or other objects embedded that could poke a hole in the tire and cause an air leak. 7. Check the sidewalls to make sure there are no gouges, cuts or bulges. Tire inflation information All tires with Steel Carcass Plies (if equipped): This type of tire utilizes steel cords in the sidewalls. As such, they cannot be treated like normal light truck tires. Tire service, including adjusting tire pressure, must be performed by personnel trained, supervised and equipped according to Federal Occupational Safety and Health Administration (OSHA) regulations. For example, during any procedure involving tire inflation, the technician or individual must utilize a remote inflation device, and ensure that all persons are clear of the trajectory area. WARNING: An inflated tire and rim can be very dangerous if improperly used, serviced or maintained. To reduce the risk of serious injury, never attempt to re-inflate a tire which has been run flat or seriously under-inflated without first removing the tire from the wheel assembly for inspection. Do not attempt to add air to tires or replace tires or wheels without first taking precautions to protect persons and property. 232 2009 F-250/350/450/550 (f23) Owners Guide, 3rd Printing USA (fus)
