| As of 01.05.2006, a change to the German road traffic regulations (StVO) came into force which caused the following supplement to be made: "The equipment in motor vehicles has to be adapted to the weather conditions. In particular, this includes suitable tyres and antifreeze in the windscreen washing system." |
| Please point out to customers that, since May 1st 2006, they are legally obliged to adapt their vehicle's equipment, particularly the tyres, to winter weather conditions. |
| For driving in winter, we recommend that the vehicle be equipped with winter tyres in the sizes recommended in table 2 of the parts certificates. |
| All tyre sizes listed in the vehicle documents can also be used as winter tyres. |
| The handling characteristics may be affected by the use of winter tyres and the possible change in the dimensions of the wheel and tyre. Therefore, when using winter tyres, you must adapt your speed to the changed handling characteristics and to the road conditions. |
| To achieve the best possible handling, winter tyres must be fitted on all wheels. |
| If the vehicle is equipped with rims other than the factory-fitted rims, you must take the following into consideration when you fit winter tyres: |
| t
| Wheels and wheel bolts are matched. |
| t
| Whenever the wheels are changed, corresponding wheel bolts of the correct length and with the correctly shaped tapered seats are used → Remark. The secure fit of the wheels and the functioning of the brakes depends this. |
| t
| The suitability of winter tyres with less than 4…5 mm tread depth for winter operation is limited. |
| t
| Some countries require winter tyres to have a tread depth of at least 4 mm. |
| t
| We recommend that winter tyres be replaced after no more than six years. The special „winter properties“ of these tyres decline with age, regardless of how much they are used. |

| A spherical cap is the curved surface of a section of a sphere cut by a plane. The tapered seats on the wheel bolt and in the wheel (rim) in the wheel bolt holes are spherical caps. |
