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 included in the Volvo
genuine accessories range. There are two
types of wheel nut, depending on whether
the rims are made of steel or aluminium.
Tighten the wheel nuts to 90 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 va-
riety may also be used.
Aluminium rims – bulge acorn wheel
nuts
(2)
Only use the bulge acorn variety of nuts with
aluminium rims. These differ markedly from
other nut types as they have a rotating coni-
cal washer.
Locking wheel nuts
Locking wheel nuts can be used on both alu-
minium and steel rims. If steel rims with lock-
ing wheel 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 ordinary
wheel replaced or repaired. Replace the
spare wheel with a normal wheel as soon as
possible. 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
90 Nm. Overtightening can damage the
nuts and the bolts.
WARNING
Never use standard nuts for aluminium
rims. The wheel could come loose.
NOTE
These nuts may also be used with steel
rims.

IMPORTANT
The car must never be driven fitted with
more than one "Temporary Spare" wheel.
