Tram Tracking???

[BA.]

Tramlining happens alot with wider tires. Not much to be done about it, certain tread patterns tramline less than others, but it's mostly down to the individual vehicle/suspension/tire combo. Even new cars suffer from this, proper suspension tuning and tire selection can reduce it but never get rid of it entirely.

My car suffered terribly in Denver from the worn road lanes that are used the most (center lane) in winter.
In any case, I had Goodyear directional tires (245s) and tried adding 2 lbs of air, it helped a little, I had the car aligned by a shop that knew what they were doing (most shops would only work to factory specs). The alignment helped a lot, I also adjusted the on-center nut on the steering box, but switching to another brand tire cured the problem (non-directionals too BTW).
Years later I replaced a slightly worn steering rag joint which I am sure compounded some of the problems.
I since have moved from Colorado, so I could not confirm if that fully solved all the issues.
HTH

My experience is the same as these 2 guys. Changing of tire brand/model does and can make a difference, and alignment settings can also help. (of course worn out suspension components will exacerbate the issue)

I had the issue, and read up on it a lot at ClubLexus.com for my GS400 and also read some others' comments at TireRack.com.



Good Luck getting it sorted out.
