Tires

D
For service conversions, the tire/disc wheel specifications and

dimensions should be compared with the entries in the
registration papers.

D
When mounting tires, the tires and rims must be carefully

matched in order to guarantee the concentricity of the wheel.

Identification of matching points on:

- Tires with a colored dot on the outside of the tire,

- Sheet steel disk wheel by a colored dot or punch mark on the

outside of the wheel,

- Perform this operation at the valve stem hole on light-alloy

disk wheels

With an additional paint spot or punch mark in the rim base

for the 140 Model Series.

D
Always replace the rubber valve.

-----------------------------------------------------------------------------------------
D

Damaged and defective tires must always be replaced. The

repair methods employed in the tire trade are not approved by

Mercedes-Benz. Small nicks (<0.8mm) on the tire's sidewall do

not usually pose a cause for concern, and continued use of

such tires is approved

D When replacing just one tire, install it on the front of the vehicle.

This does not apply to vehicles with different tires of varying

specifications on the front and rear wheels.

D
Only use tires listed in the valid Service Information bulletins

and repair instructions.

D
If the permissible maximum speed of an M+S tire is below the

maximum speed of the vehicle, an appropriate adhesive plate

must be attached in the driver's field of view.

-----------------------------------------------------------------------------------------

D
Tires permissible for higher speeds may be used.

D
Always fit all rims with tires of the same design, make and

version.

-----------------------------------------------------------------------------------------
D

Run in new tires for approx. 100 km at moderate speed.

D
Handed tires must be installed according to the arrow on the

side wall of the tire.

D
Tires are subject to an aging process with negative effects on

the properties of the tire. In order to ensure optimum

effectiveness in winter, M+S tires should not be used for longer

than 3 years.

-----------------------------------------------------------------------------------------

Tire pressure

(For specified values see tire pressure table in the fuel filler flap, on

the Vaneo BM 414 see B-pillar on the passenger side).
Too low tire pressure increases the rolling resistance and increases

the flexing energy of the tire. This causes the critical temperature limit

to be exceeded (carcass detachment) and destroys the tire. Respond

to loss of tire pressure by determining the source and replacing the

tire as indicated.

Cleaning

Using a spray wand with high-pressure nozzles to clean the wheel

can lead to tire damage. Such damage occurs especially on the tire

side walls. The following should be observed when using flat jet

nozzles:

D
Maintain a minimum distance of 300 mm

D
Do not direct the water jet at a single point on the surface of the

tire for any length of time.

-----------------------------------------------------------------------------------------
Mounting in bearings

Before putting into storage, clean tires thoroughly and check for
damage and adequate tread depth. Mark the position and running

direction of the tires with chalk. Do not store tires outdoors. Under the

influence of sunlight, heat, moving air and ozone the rubber looses

elasticity and strength, ages more quickly and becomes cracked.

Storage areas should be dry, cool and dark. Avoid drafts by keeping

doors and windows closed as much as possible. Do not bring tires

into contact with gasoline, oil or other greases as they dissolve the

rubber.

Disposal

Collection, storage and disposal should be performed in accordance

with the legal requirements and the company's own regulations.

Rims
D
When changing wheels, for instance, when replacing steel

wheels with light-alloy rims, ensure that the wheel bolts

required for the spare wheel are stored in a clearly visible

location.

D
Since December 1994 models 202 and 124 with special

equipment light alloy disk wheels, are supplied with a sheet

steel spare wheel instead of a light alloy spare wheel. The

necessary wheel bolts are included with the steel spare wheel.

D
Only use approved Mercedes-Benz rims of the same version.

D
Reinforced steel rims are identified by a sticker on the wheel

disc.

D
The wheel bolts on steel and light-alloy rims should always be

tightened to the specified tightening torque using a torque
wrench.

It is not necessary to retorque the lug bolts after approximately

100 to 500 km.
D

The seat for the tire bead must display no corrosion marks.

D
Before inserting a new rubber valve, clean the contact surfaces

on the disk wheel.

On sheet steel-disk wheel wheel trims must be fitted to support

the rubber valve.


Damaged or deformed rims must not be repaired.

Tire pressure monitor
D
Before replacing a tire, check the date of manufacturer of the

wheel sensor: wheel sensors which are more than 5 years old

must be replaced.

D
Use STAR DIAGNOSIS to read out the actual values of the tire

pressure monitor. Check the remaining life of the wheel sensor

battery, replace the wheel sensor if necessary.
