SERVICING YOUR TIRES
Tire inflation information
The E550 vehicles are equipped with a tire that is an all-steel radial.
All-steel radial tires utilize steel cords in the sidewalls, and also require
increased inflation pressures of up to 95 psi. 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 insure that all persons are clear of the trajectory
area.
WARNINGAn 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.
