Outside edge drivers side tire wear on a wagon

[vc commodore]

I know they were 60% worn but they weren’t shouldered at all, it was just depth of tread. I’ll swap em side to side and see what happens.

It's either the old tyres had the shoulder wear or you have a problem in the rear of the car, like a bent axle.

Maybe post a picture up of the rear of the car, directly from behind and from the side, showing how the rear tyres are standing....Might be able to pick if there is a problem with the axles, as that is the only thing that can cause the problem you are describing, from a suspension point of view

Will do tomorrow.
I’ve been thinking about how to measure if toe angle is out. I think I’ll put the rear wheels up on blocks so I can measure the outer edges of the axle position relative to some point under the car. Who know if the fronts are where they are meant to be or if body panels are equal side to side on a 30 year old battle axe.

Any reason a wheel alignment shop can't measure the toe in? They do it on my VQ rears.

You may then find the other wheel already has wear on the inside and if so, then you have possibly done a centre pin on the leaf springs and it is crabbing down the road.

Coil sprung rear, so I think we can discount that...

Will be interested to get pictures from behind and beside the car to see how the wheel is sitting

I wish I could say the same....

I used to swap my rear tyres from left to right to try mitigate camber wear, I was told once a tyre wears in a particular spot, it will continue to deteriorate faster in that spot regardless of road contact.

VQ is IRS. Wagon will be live. adjustable panhard is about the extent of adjustments.

If the tyre had edge wear enough it will keep getting worse even when thrown on the back. You normally have to get to the side wear fairly early on to stop it progressing.
