Title: Tramlining
Post by: greenman on 17 July 2010, 19:34:35

What causes tramlining? I,ve noticed car seems to be veering with ruts in the road.

Also
worn (or soft) wishbone bushes
soft doughnut bushes (in the rear subframe)
worn lower balljoints
wear in any of the steering linkages

As cem pointed out though wider tyres put more off centre loads on the wheels which make any shortcomings in the suspension more obvious.

My present car has 235/45-17 tyres on it and it is a nightmare in any motorway lane that has lorry ruts. I am going to fit new wishbones and doughnut bushes in the next few days & I have hopes of a big improvement :y

I,ve fitted 245 40 18,s a couple of weeks ago so that,s probably the cause. Many thanks.

Not the cause, no, but as said above, amplifying/highlighting existing problems. You'd be well advised to thoroughly check suspension and steering bushes and wheel alignment. I've driven cars with thicker tyres than that that don't veer all over the place :)

.....falcon tyres, ESP the 912 model, similar reports on here re pirelli p zero, avoid these.

Inspect for suspension and steering  faults.

Replace as required, including any suspension upgrades if your into that

Visit wheels in motion web site for full geometric set up

Then, and only then, fit new tyres of a top end brand such as conti, Dunlop, bridgestone, don't buy anything cheaper than kumho ku31, anything cheeper has potentially catastrophic lack of grip in the wet.

Don't you mean Falken Chris? The FK452's are definitely bad for tramlining.

I second that comment.
Had some on the front of the saloon when I had it.
Swopped them to the rear (can't remember what was on the rear, but different) and tramlining stopped  :y job done.

FWIW I find this gets worse with tyre wear, so now I rotate my tyres front-to-rear so the better tyres are always on the front.

That's not ideal for other reasons but as long as the rears are changed before they get dangerously lacking in grip, it works for me.
