Hi All,
Does anyone out there have any knowledge of what are the significant factors that cause tramlining ?
The following are things that i believe effect it but are there any others ? And Which of these are the most significant ?
Wheel Size
Tyre Size
Tyre Pressure ( Under or over ?)
What about:
Geometry (Standard v ProDrive and/or Camber v Caster)

Too many trams!
If only we really knew!
Geometry is clearly one - tyre construction and size is very significant.
Wear in steering system
And all others you mention
Tyres and geometry are easy to check

Andy,
I've had my car from new(Aug 97) and have slowly improved it from then. Fist was a set of 17" wheels(from 15") with 215/40/17. This improved the handling by reducing body roll slightly/better turn in and improving grip a bit. But the downside was I had a lot more tramlining.
I then upgraded the suspension to Leda B and this eliminated the tramlining. The geometry was changed at that time - did the suspension or the geometry make the bigeer difference ??

I'm agree with Brendan 100% on this, changed from he 010's to F1's and virtually eliminated it, my f1's have now done 16K and no noticeable tramlining!

Uneven tyre wear certainly makes it worse. My P-Zeroes on the front were getting a bit 'cone-shaped', with the tread reducing evenly towards the inside (due to Prodrive camber settings).
The tramlining was getting really annoying. I swapped the tyres front-to-back and that pretty well eliminated the problem.
I'd get the bumpsteer mod done to sort the geometry out once and for all, but Admiral said they wouldn't insure me if I did....

AWD makes it worse (no not you AWD - get back to the Muppet forum) because all four wheels are seaching for grip on frequently uneven/differing surfaces.
