General information on rim/tire conversions - AH40.10-P-1050-01A

MODEL 124, 129, 140, 163, 164, 166, 168, 169, 170, 171, 199, 201, 202, 203, 204, 207, 208, 209, 210, 211, 212, 215, 216, 219, 220, 221, 230, 240, 245, 251, 292, 461, 463, 906 

On vehicles with vehicle documents up to 30.9.05 

When tires of dimensions other than those listed as standard in the vehicle documents are mounted within the Federal Republic of Germany, the department of motor vehicles must enter the dimensions of the non-standard tires in the vehicle's registration slip and title. The condition for this approval is a prior positive appraisal issued by a technical officer at an officially recognized vehicle inspection station (TUV). In most cases, the testing stations already have such appraisals for the tire change options approved by Mercedes-Benz.

Always observe all national and local regulations when mounting tires in other countries.

Light alloy wheels are only compulsory when the vehicle documents at Sub-section 33 to Sub-section 20 to 23 contain the restriction A. LM. Felge.

The entry "A.Felge" in the vehicle documents merely stands for "Auf Felge," or "on rim," and does not indicate that aluminum wheels are required.

On vehicles with vehicle documents as of 1.10.05 

With wheel/tire dimensions which are not entered in the vehicle documents, either a COC paper (certificate of conformity) or a corresponding expert's report on the parts must be available. The permissible wheel/tire combination must be listed in the homologation certificate Part 1 under number 15 or in the certificate of conformity (COC) paper under number 32 and 50 or in the required Technical Inspection Association report.

For all vehicles 

General Operating Permit (GOP) is issued for each individual custom wheel by the Federal Office for Motor Vehicles (KBA); approval is always issued in combination with a specific vehicle type. It is usually supplied at the same time as the wheel is purchased and is a precondition for the preparation of the appraisal.

With many rim/tire/combination conditions listed in the GOP are to be taken into account (e.g. body change, vehicle modification).

The assignment of the speed rating of the tires is based on the vehicle's maximum permissible speed.

On winter tires with a speed index V (up to 240 km/h) it is to be observed that these have a lower load capacity. These tires are thus not approved for all applications. The reduction in axle load allowance may lead to a lower permissible maximum speed.

These facts should be pointed out to customers whose vehicle is equipped with V-tires.

Retail tire suppliers have access to load reduction tables.
