Wear and maintenanceThe correct tyre pressure results in more even
wear, see page 301. Driving style, tyre pres-
sure, climate and road condition affect how
quickly your tyres age and wear. To avoid dif-
ferences in tread depth and to prevent wear
patterns arising, the front and rear wheels can
be switched with each other. A suitable dis-
tance for the first change is approx. 5000 km
and then at 10 000 km intervals. Volvo recom-
mends that you contact an authorised Volvo
workshop for checking if you are uncertain
about tread depth. If significant differences in
wear (>1 mm difference in tread depth)
between tyres have already occurred, the least
worn tyres must always be placed on the rear.
Understeer is normally easier to correct than
oversteer, and leads to the car continuing for-
wards in a straight line rather than having the
rear end skidding to one side, resulting in pos-
sible complete loss of control over the car. This
is why it is important for the rear wheels never
to lose grip before the front wheels.
Wheels should be stored lying down or hanging
up - and not standing up.
WARNING
A damaged tyre can lead to loss of control
of the car.
Tyres with tread wear indicators
G021829
Tread wear indicators.
Tread wear indicators are narrow treadless
bands across the width of the tread. On the
side of the tyre are the letters TWI (Tread Wear
Indicator). When the tyre's tread depth is down
to 1.6 mm, the tread depth will be level in height
with the tread wear indicators. Change to new
tyres as soon as possible. Remember that
tyres with little tread depth provide very poor
grip in rain and snow.
Rims and wheel bolts
IMPORTANT
The wheel bolts must be tightened to
140 Nm. Overtightening can damage the
nuts and the bolts.
Only use rims that are tested and approved by
Volvo and which are Volvo genuine accesso-
ries. Check the torque with a torque wrench.
Locking wheel bolts*Locking wheel bolts* can be used on both alu-
minium and steel rims. Under the cargo area
floor there is space for the sleeve for the lock-
able wheel bolts.
Tools
Located under the cargo area floor are the
car's towing eye, jack* and wheel wrench*.
There is also space for the sleeve for the lock-
able wheel bolts.

jack down so it is pressed squarely on the
ground.
IMPORTANT
The ground must be firm, smooth and level.
8. Lift the car so that the wheel is free.
Remove the wheel bolts and lift off the
wheel.
Installation
1. Clean the contact surfaces between wheel
and hub.
2. Put on the wheel. Tighten the wheel bolts
thoroughly.3. Lower the car so that the wheels cannot
rotate.
4. Tighten the wheel bolts crosswise. It is
important that the wheel bolts are tight-
ened properly. Tighten to 140 Nm. Check
the torque with a torque wrench.
5. Refit any full wheel covers.
NOTE
The wheel cover outlet for the valve must be
positioned over the valve on the wheel rim
during fitting.
WARNING
Never crawl under the car when it is raised
on the jack.
Passengers must leave the car when it is
raised on the jack.
Park the car so that passengers have the car
- or preferably a crash barrier - between
them and the road.
Spare wheel*
The spare wheel (Temporary spare) is only
intended for use temporarily and must be
replaced by an ordinary wheel as soon as pos-
sible. The car's handling may be altered by the
use of the spare wheel. The spare wheel is
smaller than the normal wheel. The car's
ground clearance is affected accordingly. Pay
attention to high kerbs and do not machine
wash the car. If the spare wheel is fitted on the
front axle, you cannot use snow chains at the
same time. On all-wheel drive cars the drive on
the rear axle can be disconnected. The spare
wheel must not be repaired. The correct tyre
pressure for the spare wheel is stated in the
tyre pressure table, see page 366.
