35A
aIn some countries, the use of lead weights is forbid-
den; in this case it is recommended to use ZAMAK
weights instead.
Only use weights provided by the Parts Department.
aRemove the wheels (see 35A, Wheels and tyres,
Wheel: Removal - Refitting, page 35A-1) .
aAlways clean the wheel, disc, and hub bearing sur-
faces.
III - PROCEDURE FOR BALANCING THE WHEEL IN
QUESTION
aMake sure that the wheel balancer bearing surface
and all the centring equipment (ring, thrust plate,
etc.) are kept clean.
aTry not to scratch the (alloy) wheel rim with the
wheel tightening device.aThe wheel is fitted on the wheel balancer as follows:
- (5) ring,
- (6) wheel balancer back-plate,
- (7) wheel tightening device (certain alloy wheels
require a device 200 mm in diameter to ensure that
the wheel has been correctly tightened),
- (8) outer wheel plane,
- (9) wheel.
aPlace the wheel on the wheel balancer, with the
valve at the top, then lock the wheel in place.
aRemove any stones trapped in the tyre tread.

aEnter the specific wheel parameters when starting
the wheel balancer.
aStart the wheel balancer and check the wheel bal-
ance, which should be 0 g on each plane of the
wheel.
aIf this is not the case, remove the old wheel balanc-
ing weights and repeat the wheel balancing proce-
dure, checking that the wheel balance equals 0 on
each wheel plane.
IV - FINAL OPERATION
aRefit the wheel (see 35A, Wheels and tyres,
Wheel: Removal - Refitting, page 35A-1) . WARNING
To avoid detachment of the balance weights, use
only weights which correspond to the vehicle
wheel rims.

REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aRemove:
-the wheel in question (see 35A, Wheels and tyres,
Wheel: Removal - Refitting, page 35A-1) ,
-the balance weights,
-the valve mechanism.
II - OPERATION FOR REMOVAL OF PART
CONCERNED
aDetach:
-the bead from the outside of the tyre, starting with
the side opposite the valve,
-the bead from the inside of the tyre.aPosition the tyre lever approximately 15 cm from the
valve on the outside of the wheel rim in order to re-
move the exterior bead from the tyre.
aRemove the exterior bead of the tyre, finishing at the
valve.
aPosition the tyre lever approximately 15 cm from the
valve on the outside of the wheel rim in order to re-
move the bead from inside the tyre.
aRemove the interior bead of the tyre, finishing at the
valve.
REFITTING
I - REFITTING PREPARATION OPERATION
aparts always to be replaced: Tyre valve
aLubricate the two tyre beads correctly using the
TYRE PASTE (see Vehicle: Parts and consum-
ables for the repair) (04B, Consumables - Prod-
ucts).
II - REFITTING OPERATION FOR PART
CONCERNED
aEngage the lower tyre bead approximately 15 cm af-
ter the valve.
aFinish fitting the tyre at the valve.
aFit the exterior bead approximately 15 cm after the
valve using the tyre lever.
aInflate the tyre to 3.5 bar to press the tyre beads
against the wheel rim.

tion, page 35A-10) .
aBalance the wheel (see 35A, Wheels and tyres,
Wheel: Balancing, page 35A-4) .
aRefit the wheel in question (see 35A, Wheels and
tyres, Wheel: Removal - Refitting, page 35A-1) . Note:
It is not necessary to drive the vehicle before and
after a new wheel is balanced.

IDENTIFICATION
1 - Marking
There are two types of identification marking on the
wheel rims:
-engraved marking for steel wheel rims,
-cast marking for alloy wheel rims.
The marking gives the main dimensional specifications
of the wheel rim.
This marking may be:
-complete, for example 6 J 15 5 CH 36,
-simplified, for example 6 J 15.
There are 3 types of wheel rim edges (2) :
-those with two flat edges,
-those with two raised edges,
-those with one flat edge and one raised edge.2 - Installation diameter for the wheel bolts
The wheel bolts are positioned with a pitch circle dia-
meter of:
-5 holes: 108 mm,
-4 holes: 100 mm.
3 - Rim run-out
The maximum run-out is measured at the wheel rim
edge (7) .
Steel wheel rims: 0.8 mm
Alloy wheel rims: 0.3 mm
4 - Out-of-roundness
The maximum out-of-round value is measured on the
tyre bead bearing surface.
