embedded that could poke a hole in the tire and cause an air leak.

Tire Inflation Information
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.
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 regulations. For example, during any procedure involving
tire inflation, the technician or individual must utilize a remote inflation
device, and make sure that all persons are clear of the trajectory area.
