Emergency Braking Test of the Ice and Snow Tires on Iced Drum Tester

This paper describes a test method that evaluates the emergency braking capability of a tire on ice using an ice-covered drum tester. The value of the braking force is affected by the amount of crushed ice stuck to the tire. With a low rotation speed for the tire, this effect can be reduced.

Utilizing this technique, braking force - velocity characteristics on ice at various temperature are obtained.
