WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Avoid wheelspin. This can lead to damage to the drive train.
The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on a wet surface as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
The safe speed on a wet, snow covered or icy road is always lower than on dry road surfaces.
You should pay special attention to road conditions when temperatures are around freezing point.
Mercedes-Benz recommends a minimum tread depth of 1/6 in (4 mm) on all four winter tires. Observe the legally required minimum tire tread depth . Winter tires can reduce the braking distance on snow-covered surfaces in comparison with summer tires.
The braking distance is still much further than on surfaces that are not icy or covered with snow. Take appropriate care when driving.
