288 MAINTENANCE AND LUBRICATION
Tires
DANGER
Tires used on multipiece rims must be assembled and inflated only by experienced,
qualified personnel. Tires must be inflated in a safety cage whenever possible. If,
however, a safety cage is not available, use a portable lock-ring guard. The tire
must be deflated prior to removal of the tire-and-rim assembly from the vehicle.
Remove the valve core to ensure complete deflation.
DANGER
NEVER position your body in front of the rim during inflation.
CAUTION
NEVER use water-based sealants, puncture proofing, or liquid balance materials
containing water in All-Steel Radial Ply truck tires.
Inflation Pressure
To ensure maximum mileage and overall performance from your tires, it is
essential that they operate at the correct inflation pressure for the load carried.
Inflation pressure should be checked daily while the tires are cold. Always use
an accurate tire pressure gauge. NEVER bleed air from a hot tire, as it will
then be underinflated. Refer to the specific tire manufacturer’s data books, or
to the vehicle certification label for a complete listing of tire inflation pressures.
For additional information concerning tire care, refer to the
Maintenance and
Lubrication Manual .
WARNING
UNDER NO CIRCUMSTANCES should you drive on underinflated or
overloaded tires. A tire in this condition builds up excessive heat which can
result in sudden tire destruction, property damage and personal injury.
