WHEELS
General
Due to the size, equipment needed and the procedures used to change
wheels, this should be done through the Volvo Truck dealer. By having
an expert technician perform this procedure, personal injury and
property damage may be avoided.
When replacing the wheel equipment or tires, use the
same size wheels or tires as originally manufactured.
Changing the tire or wheel size will affect brake
performance. If changing tire size, ABS and
speedometer must be recalibrated.
Check Wheel Nuts Torque
Failure to properly tighten the wheel nuts can
result in the breakage of wheel studs and the
subsequent loss of wheels. Loss of vehicle control
and serious personal injury or death can occur.
Check all wheel nuts torque after the first 80 to 160 km (50 to
100 miles) and the first 80 to 160 km (50 to 100 miles) after each tire
service. This applies to both single and dual wheels in connection with
normal service but should be performed at least every six months.
The torque check is particularly important when rims or brake drums
are newly painted. Paint can flake off from these surfaces, causing the
nuts to lose their grip and the wheel to loosen.
See the Operator's Manual Vehicle Maintenance for correct procedures
on tightening the wheel nuts.
