This is not the term tramlining mate.
Tramlining is where a car follows the dips and grooves worn into any road, be it a long groove, or simply a section of dips in the road, its called tramlining as trams can only go where the rails go, in effect being led by the tram lines, which the term is carried over with road vehicles if they do the above.
Wider tyres can cause more tramlining as the size a weight of the tyre will always try to follow the natual line in the road which is why a car will always fall a groove in the road.
Thats what he meant...The lorrys create ruts in the road which the car dips in and out of as it tramlines. Nearly every car will do it though as the roads are so bad!
I put 215's on my civic (std are 205's) which made it grip more but the lower profile made it ride alot worse. I ran 235's/265's on the M3 (std are 225/255) and turn in was better but overall grip wasn't because i went from michelins to Falkens. They looked good but were crap! If you're running cheap tyres, simply buying the same size top spec ones will make more difference! Or try wheel spacers for extra track...But extra weight on the end of the axle!
Remember its iilegal for the tyre to stick out further than the arches. That impreza would be illegal over here...And looks crap!
