tram-lining is when the tires follow ruts/ imperfections in the road surface, yanking the steering wheel back and forth. It is exacerbated by the toe setting (much worse with toe-out).

Generally the grippier the tires, the more they are prone to tram-lining. And the more aggressive the front-end set-up (i.e., skewed towards track), the more it will tram-line.
