As I'm sure most people know, ideal camber setting is -1.10. Mine is set to -1.15 which is normal with sports/ lowered suspension.

With those settings you might expect to see the majority of the wear on the inner edge, by the time the tyre is worn out.

So, question is, why is there more outside edge wear?which is shown at the bottom edge of the tyre in the pic.


The type of wear is different as you can see. The inner edge (top) is normal camber wear we're familiar with. But the outer edge wear (bottom) is different. More of a scrub, like a toe issue IMO.


Car is 30mm lowered, with front polys only. Rear bush is normal gm rubber.

Thoughts?

Heres a side on shot of outer edge with tyre size.

Hi cornering speed are both front tyres the same?

Yes. Fitted in pairs. At the same time. Same model.

One might argue, that given the wear, the settings are prety good, as the wear is even, ish.

My only real issue is, with -1.15 the straight line stability is not as good as -1.10. It's still good/acceptable, but it's noticeably less stable.

With a slight reservation on the toe setting for part poly. I suspect this is probably as good as it gets. Given the wear shown.

What about the wear? Or is it only nearside

Sorry , yes. Within reason, the wear is almost identical on both front wheels. If being really picky, the outside edge wear on this tyre is fractionally worse.

Tyre shown is drivers side.

Only thing of note is, these tyres had a faulty steering idler fitted to the car for about 6months.

Get your self one of these. Save fuel and tyre wear.

Which would cause toe deflection beyond the normal geometric tolerances of the suspension can't quite visualise the effect though...

Constant adjustment of the steering to account for a varying toe setting/flapping pas side wheel.

So the toe is varying constantly. And excessively. Add in a possibly excess standard setting of -0.5 each side given the polys, and add in a corner....

That sweeping left hander as you come of the M4 won't be helping any

To Not Reading? Yes won't help at all.

But it's usually queued back with traffic.

When was the last time you had geomatry checked?

[omega3000]

had exactly the same on my old elite when i bought it , changed the drop links and track rod ends and had no more issues .
