The role of tread design in skid resistance under winter driving conditions. Paper presented at the 52nd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1973.

The role of tread design in skid resistance under winter driving conditions is considerable, providing the tyre is not operated at differential interface velocities that exceed the peak tractive resistance of the material on which the tyre is driven. The tyre must continue to turn if the tread design is to be meaningful in skid resistance. A figure is presented which illustrates the relative tractive performance of the same paired drive tyres over a range of specific winter environments.
