M+S tires

At temperatures below 45 °F (+7 °C), use winter tires or all-season tires. Both types of tire are identified by the M+S marking.

Only winter tires bearing the snowflake snowflake symbol in addition to the M+S marking provide the best possible grip in wintry road conditions. Only these tires will allow driving safety systems such as ABS and ESP® to function optimally in winter, as these tires have been designed specifically for driving on snow.

Use M+S tires of the same make and tread on all wheels to maintain safe handling characteristics.

M+S tires with a tread depth of less than 1/6 WARNING
M+S tires with a tread depth of less than 1/6 inch (4 mm) must be replaced. They are no longer suitable for winter operation.

Always observe the maximum permissible speed specified for the M+S tires you have mounted.

Once you have mounted the winter tires:
– Check the tire pressures.
– Restart the tire pressure loss warning system.

If you mount the spare wheel when driving WARNING
If you mount the spare wheel when driving with M+S tires, bear in mind that driving stability will be impaired due to unstable cornering characteristics caused by the different tire characteristics. Adapt your style of driving accordingly.
Have the spare wheel replaced by a normal wheel with an M+S tire at the nearest Mercedes-Benz Center.
