Hi Guys, quick question. My Omega is absolutely eating tyres on the edges.

Question is this - would knackered wishbone bushes, and a cacked steering idler cause this problem, as well as geometry?

At the moment, I don't want to risk the 150mile drive to WIM until I can get it much better, the handling is quite... scary!!

More info please, small band on the inside or outside edge?

All over the tread?

Any feathering to the inside or outside tread?

It's a tricky one, because the previous owner seems to have swapped wheels around

The fronts are wearing on the inner edge - they're probably not far from the canvas on the inner edge but the rest of the tread, incl outer edge, is fine.

The rears seem to have wear on both edges, moreso inner...

At a guess

Rears are or have been under inflated.

Fronts have the camber out

So, camber is more related to strutt length than wishbones (which I suspet will ahev more impact on Caster and Toe) and will be due to the springs weakening with age (not an issue)

Do you still think it's the wishbone bushes that's causing it to feel all over the place?
I feel like whenever the car hits a rut or a line in the road, it tries to take the steering wheel off me - it's like driving with a very underinflated pair of tyres!

[JamesV6CDX]

I can't seem to make the steering idler move, what's the best way to prod it around to check for play?

[Marks DTM Calib]

Wishbones are causing bump steer so yes, they are an issue, tyre wear wont be directly caused by wishbones though

[Marks DTM Calib]

Your looking for vertical play in the idler when wiggling the passenger wheel in the 3-9 Oclock positions

Excellent - as long as I can get the handling so it feels safe, I will then drive it to WIM to be finished off

Perfect. I'll just finish me cuppa and go out there with the jack

Shame buypartsby sent me the wrong bones, I would have had them fitted today

You have discribed my car,nsf tyre outside edge osf inside edge and all over the place on uneven surfaces.
On Friday had wishbones changed (bushes shot) also offside track rod also shot
 I have just had it tracked and it was 10 degrees  tow in ?
Now its a dream and no rattles

Sadly, they wont have checked and adjusted the camber which will have been a major contributor to the tyre wear.

Agreed, I phoned a few places yesterday.

Me: "Can you do full geometry on my Omega"
Them: "Sure, sir, no problem".
Me "Can you confirm if this includes camber?
Them: "Afraid not sir, that's too tricky"
Me: Well it's not full geometry then, is it!

First place I took mine to didn't adjust the camber, and then, as I was leaving, said "oh, you might find you get inner shoulder wear cos there's quite a lot of camber". When I asked why they didn't adjust it - "oh, we have a policy of not adjusting anything that's "in the green".



Change the wishbones then take it to WIM. In the meanwhile you might be able to effect a rough camber adjustment that'll stop it eating the tyres so badly using a flat surface, a spirit level and a bit of trigonometry.

Do you still fancy doing both cars together?
I could drive it up the M4 when it's quiet
