Mercedes-Benz GL-Class: Traction
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.
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.
WARNING
If ice has formed on the road, tire traction will
be substantially reduced. Under such weather
conditions, drive, steer and brake with
extreme caution.
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 the freezing point.
Mercedes-Benz recommends a minimum tire tread depth of 1/6 in (4 mm) for all four winter tires to maintain normal driving characteristics in winter. Winter tires can reduce the braking distance on snow covered surfaces in comparison to summer tires.
Stopping distance, however, is still considerably greater than when the road is not covered with ice or snow. Take appropriate care when driving.
Avoid wheelspin. This can lead to damage to the drive train.
Tread wear
