Ford F-650 2008 User Manual page 201

Use only the same type and style wheels and mounting hardware
to replace original parts. Failure to do so may result in an
assembly that looks fine, but does not fit together properly. This could
possibly cause wheel or fastener failures which could result in property
damage, personal injury or death.
Note: Do not attempt to mix stud-piloted wheels or fasteners with
hub-piloted wheels or fasteners.
Note: Do not change from aluminum wheels to steel wheels or
vice-versa without changing the mounting hardware required or, with
flange-nut mounting systems, changing the hub and stud assembly.
WHEEL NUT TORQUE
Size Nut mounting
22 mm Flange
Note: Do not use lubrication on dry threads. Where excessive corrosion
exists, a light coat of lubricant on the first three threads of the stud bolt
is permitted. Keep lubricant away from:
• Hex nut and rim clamp contact surfaces.
• Cap nut ball face and ball seat on the disc wheel.
• Flange nut washer surface and flat on the disc wheel.
TIRE INFORMATION
Inflation
Always maintain your tires in good condition. Frequently check
and maintain correct inflation pressures as specified by tire
manufacturers. Inspect periodically for abnormal wear patterns and

trained personnel with proper equipment and correct procedures to
mount or remove tires and wheels. Failure to adhere to these warnings
could result in wheel or tire malfunction, damage to your vehicle,
personal injury, or death.
