Winter traction : effect of tread compound. Paper presented at the 52nd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1973.

Research work on traction on ice is reported. The low friction of rubber on ice arises from its self-lubricating polymer on winter traction appears to be small and the styrene butadiene rubber-butadiene rubber blinds used in North America are probably near optimum for overall performance. There appears to be a correlation between ice-friction and compound hardness with no evidence of specific polymer effects. The hardness effect is discussed as well as the effects of the use of very high poly-butadiene blends.
