AH40.10-P-9411-01MCU Information On Tires / Rims

^ Replace valve, general.
^ 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 by means of a colored dot on the outboard side of the tire
- on sheet steel disk wheel, by color dot or punch mark on the outboard side of wheel
- on light alloy disk wheel, generally at valve hole

^ Always provide all disk wheels with tires of the same construction, same make and same design.
^ Tires approved for higher speeds may be used.
^ Handed tires must be installed according to the arrow on the side wall of the tire.
^ 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.

Tires
^ For service conversions, the tire/disk wheel specifications driver and dimensions should be compared with the entries in the registration papers.
^ Damaged and defective tires must always be replaced. The repair methods employed in the tire trade are not approved by DaimlerChrysler. Small nicks (< 0.8 mm) on the side wall of the tire do not usually pose a cause for concern, and continued use of such tires is approved.
^ Only use tires listed in the valid Service Information bulletins and repair instructions.

Tire pressure
(specified values, see tire pressure chart in door cutout on driver and 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. When using flat jet nozzles, observe the following instructions:
^ Maintain a distance of at least 300 mm
^ Do not direct the water jet at a single point on the surface of the tire for any length of time

Bearing system
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. The effects of sunlight, heat, moving air and ozone cause the rubber to lose its elasticity and strength, it ages faster and cracks. Storage areas should be dry, cool and dark. Avoid drafts by keeping doors and windows closed as much as possible. Do not allow tires to come into contact with gasoline, oil or greases as these can dissolve the rubber.

Disposal
Collection, storage and disposal should be performed in accordance with the legal requirements and the company's own regulations.

Rims
For safety reasons, damaged or deformed rims must not be repaired.

^ When changing wheels, e.g. from light-alloy to steel rims, ensure that the necessary wheel bolts for the spare tire are provided in an easily visible location.
^ Only use approved DaimlerChrysler rims of the same version.
^ Reinforced steel rims are identified by a sticker on the wheel disc.
^ The wheel bolts on steel and light-alloy rims should always be tightened to the specified tightening torque using a torque wrench.
Retightening the wheel bolts after approx. 60 to 300 miles is not required.
^ The seat for the tire bead must display no corrosion pits.

Vehicles with tire pressure monitor
^ Before replacing a tire, check the manufacture date of the wheel sensor. Wheel sensors, which are more than 10 years old, must be replaced.
^ Use STAR DIAGNOSIS to read out the actual values for the tire pressure monitoring system. Check the remaining life of the wheel sensor battery, replace the wheel sensor if necessary.
