Operator's Manual Vehicle Maintenance
VN, VHD 127
DANGER
DO NOT install tires with a load rating that is less than stated on the Certification
Label in the door frame. The tire could be unintentionally overloaded, leading to
an accident, causing serious personal injury or death.
DANGER
DO NOT use mismatched tires on the same axle. Always use the same type (radial
or bias ply) or size. Mixing tires on the same axle will affect the roadholding and
can lead to an accident, and serious personal injury or death.
Wheels
DANGER
Before checking the wheels, set the parking brakes, place the transmission in
neutral and chock the wheels. Failure to do so can result in unexpected vehicle
movement and can cause serious personal injury or death.
DANGER
Wheels must be serviced only by a qualified technician. DO NOT do this work
yourself. Inflated tires on wheels contain compressed air and if suddenly released,
do so with an explosive force, resulting in serious personal injury or death.
Check wheels for signs of rust streaks around the wheel nuts. This indicates looseness
(steel rims). Inspect all types of rims for cracks. Cracks can appear in many places
but typically radiate out from where a load is applied. Inspect closely around wheel
nuts, hand holes and inside circumference.
