1928 Holt & Cooke in Bur. Standards Jrnl. Res. I. 25 A considerable part of tread wear may be caused by the slipping of portions of the tread over the road surface in changing from the normal to the deflected condition and vice versa. This might be termed a scuffing action.

1955 W. H. Crouse Automotive Chassis & Body vi. 157 High-speed operation causes much more rapid tire wear because of the high temperature and greater amount of scuffing and rapid flexing to which the tires are subjected.

3. Engineering. The roughening of a metal surface designed to rub against another when the lubrication is inadequate to prevent local fusion and tearing of the two surfaces.

1941 Engineering 11 Apr. 286/1 Should a local breakdown of the lubricating-oil film occur, the two surfaces may momentarily become fused. With the reciprocating movement of the parts, a shearing action takes place,..causing disruption of the surfaces. An example of this effect, which is known as piston-ring ‘scuffing’, is seen in Fig. 1, which shows the surface of a scuffed piston ring.
