Wheels and tyres
Changing wheels
– Place the jack under the jacking point and
crank it up towards the car floor. Check
that the jack sits securely in the
anchorage. Then adjust the jack so that
its foot is positioned vertically under the
anchorage. See illustration. Do not place
wood blocks or the like under the jack as
you will not achieve full bearing capacity.
WARNING!
If the jack is positioned incorrectly, the car
could fall. Risk of injury!
– Lift the car until the wheel is free.

– Remove the wheel bolts and lift off the
wheel.
Fitting the wheel
– Clean the contract surfaces on the wheel
and hub.
– Fit the wheel. Screw the wheel nuts.
– Lower the car so that the wheel cannot
rotate.
– Tighten the wheel bolts alternately and in
torque steps. Tightening torque:
140 Nm (14.0 kpm). It is important that
they are tightened to the correct torque.
Check with a torque wrench.
– Screw the jack all the way down before
returning it to the cargo compartment.
Then secure it in place.
– Check that the new tyre has the correct
amount of pressure.
NOTE! There are two different types of wheel
bolts depending on whether or not your car
has steel or aluminium rims; bolts used with
aluminium rims have a loose, rotating ring.
Bolts used with steel rims have no rotating
ring.
Make sure to use the correct type of bolt. If
you are unsure, check with the nearest Volvo
workshop.
