Just been reading a few threads in this forum where tramlining is mentioned. I'm not familiar with the term...could someone enlighten me? Thanks in advance.

Tramlining is when the cars steering takes on a life of its own and steers along grooves or ruts in the road, hence tramlining effect.

It is most noticeable when driving slowly, say up to a set of traffic lights on a badly made road, if you take your hands off the wheel it will pull in the direction of the marks in the road.

I hope this helps.

Ahhh...now I understand. Many thanks for the clear explanation Ian. I'm not entirely sure if I'm experiencing the effect or it's just the wider (225) tyres but I've had that happen on occasion, just not all the time.

Wider tyres will make the car tramline more.
Best method to over come it is to drive slightly off line - hence missing the worn parts of the road.
The only down side to this is that you spray a lot of loose stones / debris up the side of the car - so fit mudflaps ! (stops tailgaters in their tracks :D)
