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 ã in (4 mm) on all four winter

tires. Observe the legally required minimum

tire tread depth (

Y

page 249). 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.

Temperature

G

WARNING

The temperature grade for this tire is

established for a tire that is properly inflated

and not overloaded. Excessive speed,

underinflation, or excessive loading, either

separately or in combination, can cause

excessive heat build-up and possible tire

failure.

The temperature grades are A (the highest),

B, and C. They represent the tire's resistance

to the generation of heat and its ability to

dissipate heat when tested under controlled

conditions on a specified indoor laboratory

test wheel. Sustained high temperature can

cause the material of the tire to degenerate

and reduce tire life, and excessive

temperature can lead to sudden tire failure.

The grade C corresponds to a level of

performance which all passenger car tires

must meet under the Federal Motor Vehicle

Safety Standard No. 109. Grades B and A

represent higher levels of performance on the

laboratory test wheel than the minimum

required by law.
