slippage mark

slippage mark

A small white mark (1” to 1½” wide) painted on the sidewalls of a newly fitted tire and continued to the wheel rim. This white mark detects the movement of the tire in relation to the wheel. If the mark on the tire is not aligned with the mark on the wheel, it shows that the tire has slipped on the wheel. In such a case, the tire should be removed, as the valve in the tube is likely to be damaged. Also called creep marks
