Rims and wheel nuts
Standard (1) and bulge acorn (2) wheel nuts
Only use rims that are tested and approved
by Volvo and which are Volvo genuine acces-
sories. There are two types of wheel nut,
depending on whether the rims are made of
steel or aluminium. Tighten the wheel nuts to
130 Nm. Check the torque with a torque
wrench.
Steel rims – standard wheel nuts (1)
Steel rims are normally mounted with the
standard wheel nuts, but the bulge acorn
variety may also be used.
Aluminium rims – bulge acorn wheel
nuts (2)
Only use the bulge acorn variety of nuts with
aluminium rims. These differ from other nut
types as they have a rotating conical washer.
Locking wheel nuts
Locking wheel nuts can be used on both alu-
minium and steel rims. If steel rims with lock-
ing nuts are used in combination with wheel
covers, the locking wheel nut should be
mounted on the bolt nearest the air valve.
Otherwise the wheel cover cannot be fitted to
the rim.
Spare wheel Temporary Spare
The spare wheel 1 is only intended to be used
for the short time it takes to get the normal
wheel replaced or repaired. Replace the
spare wheel as soon as possible with a nor-
mal wheel. The car’s handling may be altered
by the use of the spare wheel.
Never drive faster than 80 km/h with a spare
wheel on the car.
IMPORTANT
The wheel nuts should be tightened to
130 Nm. Overtightening can damage the
nuts and the bolts.
