Tire performance on iced road depends on the characteristics of the ice on roads. Caused by the prohibition of application of the studded tires on the winter roads (1990-), the condition of the tires and winter roads have been varied extremely. AIST had developed the In-Door Tire Tester to study and clarify the characteristics of tires on iced roads. This paper describes an outline of this In-Door Tire Tester and inter-esting tire phenomena on iced roads obtained through the studies on this tester. One phenomenon is characteristics on the smooth ice surface and the other is the one on the rough ice surface. Namely: (1) The tire characteristics on the smooth ice depends on ice temperature and the electric conductivity of the ice for the test. (2) Braking force coefficients on the rough ice surface depend on the texture of the ice surface (amplitude and wavelength of the surface roughness).
