tyre bead is split

In these cases, the bead, which is under great tension, can be cut

into in the direction of rotation, split and/or be pinched off down

to the core wire.

It is often possible to identify the tracks of the guide roller as it was

applied or ran off where the damage occurred.

lk

Note

Both tyre beads as well as the rim shoulders must always be

coated with assembly paste .

If fitting damage remains undetected, there is a danger that the

tyre will fail later during operation.

THEREFORE!

♦ Never fit a tyre without using assembly paste .

♦ Do not allow the bead seating pressure to exceed 3 bar.

♦ Do not allow the tyre inflation pressure to exceed 4 bar.

♦ When the tyre has been fitted, reduce the tyre pressure to the

specified value.

Useful information about rims

4.7.1

Details on rims

There are several items of information on rims. The following ex‐

ample shows the information needed for clear identification of the

rim:

Part no.:

6E0 601 027 A

Size of rim:

6 J x 15

6 - Rim width in inches

J - Shape of wheel rim flange

15 - Rim diameter in inches

Wheel offset in mm:

43

Data on hump of rim shoulder:

EH2

1

Extended Hump )

1

) Raised round hump on both rim shoulders. These ensure that

when run-flat tyres are used without air pressure, they will not slip

from rim shoulder. Rims with EH2 are required only if tyres with

run-flat properties are fitted!

4.7.3

Split rim composite wheels

Split rim alloy wheels consist of several parts.

The major parts are the rim and the wheel centre. These parts are

bolted together with special bolts using a special process. This

ensures that the wheel works properly, that it is sealed and safe

and that it runs true. These requirements are not guaranteed with

workshop materials and under workshop conditions.

WARNING

You must not dismantle or repair composite wheels!

4.7.4

Half dual spacing and wheel offset

♦ „Half dual spacing (HMA)“ refers to twin wheels and defines

dimension -A- from the centre of the rim to the outer wheel

contact surface.

♦ „Wheel offset (ET)“ is dimension -B- from the centre of the rim

of the rim to the hub-sided contact surface of the wheel.

4.7.5

Care and maintenance of alloy wheel

rims

Regular care is required to maintain the decorative appearance

of alloy wheels over a long period of time.

In particular road salt and dust from brake abrasion must be thor‐

oughly washed off every 2 weeks; otherwise the finish of the alloy

wheel will suffer.

Cleaning agents

Suitable cleaning agents:

♦ Plain water or water with soft soap

♦ Water and essence of vinegar

♦ Alloy wheel cleansers without acids or strong solvents

Do not exceed the soaking time of the cleaning agent.

The shorter the recommended soaking time, the harsher and

more aggressive the cleaning agent.

Damage to finish

If the finish is damaged, for example by stones, the damage must

be repaired as quickly as possible ⇒ page 51 .

Removing adhesive residue from glued balance weights on alloy

rims

♦ Strong solvents and acids attack the finish on alloy wheels and

the surface of the wheel becomes matt and milky. Therefore,

these substances should not be used.

♦ To remove adhesive residue on alloy wheels, use alloy cleans‐

ers or a petrol-based cleanser. Do not exceed the soaking time

of the cleaning agent.

♦ After cleaning or removing adhesive residue from wheels,

rinse them with water.

4.7.6

Restoring alloy wheels

WARNING

♦ Repairing a damaged wheel using heat treatment such as

welding or the addition or removal of material is absolutely

forbidden.

♦ Damaged or deformed wheel rims or wheel rims with

cracked or deformed wheel bolt holes may not be re‐

paired.

♦ Restoration may be undertaken only with tested and ap‐

proved Genuine paint materials ⇒ Paint repair guide .

4.7.7

The valve

1 - Valve body

2 - Valve core

3 - Valve cap

1. Valve body

The rubber valve for tubeless tyres is designed to create an air-

tight seal in the hole in the rim. The elastic material of the rubber

valve body presses tightly into the hole in the rim.

WARNING

Do not damage surface of wheel rim when removing rubber

valve (scratching/cuts on paint). On steel wheels in particular,

even the smallest notches in this area may lead to corrosion,

hairline cracks or functional impairment of the component.

In the case of valves with a threaded metal base, a rubber seal is

used to seal the rim. The lateral faces of the rim hole are sealing

surfaces. They must therefore be free of rust and dirt and must

not be damaged.

2. Valve core

The valve insert has the most important job in the valve. It creates

a seal and enables the regulation of the air pressure. The small

flat seal on the valve core can only function correctly if it is free of

foreign particles, dirt and moisture. The compressed air system

must be free of water and oil!

3. Valve cap

A valve cap must always be screwed onto the valve. It prevents

dirt from getting into the valve. Dirt which may be in the valve

would reach the seal of the valve plate when the tyre is inflated

and cause a leak.

lk

The valve must be renewed every time a new tyre is fitted.

The fitting must be performed using a commercially available

puller.

Snap-in valve must always be installed moistened with a suitable

lubricant.

If the vehicle is driven without caps on the valves, there is the

danger that dirt may get into the valve. This leads to a gradual

loss of air, which in turn can lead to the destruction of the tyre.

♦ Separation of carcass and rubber ⇒ page 46

♦ Wide, circumferential furrows near the bead ⇒ page 46

♦ Stripped tread or stripped protector ⇒ page 47

WARNING

The valve cap must be fitted tightly to ensure air-tight sealing.
