Under such weather For example: conditions, drive, steer and brake with extreme caution. Tread wear TractionTemperature The safe speed on a wet, snow covered or icy 200 AA A road is always lower than on dry road surfaces. All passenger car tires must conform to U.S. You should pay special attention to road federal safety requirements in addition to conditions when temperatures are around these grades. the freezing point. Mercedes-Benz recommends a minimum tire Tread wear tread depth of 1/6 in (4 mm) for all four winter tires to maintain normal driving The tread wear grade is a comparative rating characteristics in winter. Winter tires can based on the wear rate of the tire when tested reduce the braking distance on snow covered under controlled conditions on a specified surfaces in comparison to summer tires. The U.S. government test track. For example, a braking distance is still much further than on tire graded 150 would wear one and one-half surfaces that are not icy or covered with times as well on the government test track as snow. Take appropriate care when driving. a tire graded 100. ! Avoid wheelspin. This can lead to damage The relative performance of tires depends to the drive train which is not covered by upon the actual conditions of their use, the Mercedes-Benz warranty conditions. however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road Temperature Tires and wheels characteristics and climate conditions. GWarning The temperature grade for this tire is Traction established for a tire that is properly inflated GWarning and not overloaded. Excessive speed, underinflation, or excessive loading, either The traction grade assigned to this tire is separately or in combination, can cause based on straight-ahead braking traction excessive heat build-up and possible tire tests, and does not include acceleration, failure. cornering, hydroplaning, or peak traction characteristics. The temperature grades are A (the highest), B, and C, representing the tire's resistance to The traction grades, from highest to lowest, the generation of heat and its ability to are AA, A, B, and C. These grades represent dissipate heat when tested under controlled the tire's ability to stop on a wet surface as conditions on a specified indoor laboratory measured under controlled conditions on test wheel. Sustained high temperature can specified government test surfaces of asphalt cause the material of the tire to degenerate and concrete. A tire marked C may have poor and reduce tire life, and excessive traction performance. temperature can lead to sudden tire failure. The grade C corresponds to a level of Z
