green means it is "in spec"

Nope! Well, not to wims spec. As said previosly camber should be- 1.10, yours is almost one entire degree too aggressive. 60 minutes to 1degree so 0.50 too much camber. I hope that is a before reading, not after set up...?

Toe settings show the steering wheel to be off centre. But when driven straight the combined toe of -16 is not too far off the desire -10 mins. There is an allowed error of +or- 10mins. So although can be improved, it is acceptable. Bar the off centre steering wheel.

So as said, excess camber caused your tyre wear issue.

Appologies, re read the toe settings. Miss read the scale on the right. +22 is not good either.

Yes - green is within somebody's spec, probably even within Vauxhall's spec for a new car.  But I can tell you from personal experience that -2 degrees front camber will definitely wear the insides off your front tyres.

The toe doesn't look that bad. As said, most of the "massive error" they are worrying about is because the steering wheel has been clamped in a slightly different position to when it was last set up.

22 mins on one side and -9 on the other, so in the true ahead position there's 13 mins of total toe in, or 6.5' ish each side.

Camber, on the other hand, whilst in the "green", experience says that is likely to cause rapid wear on an Omega with well bedded-in suspension.

STS on the A30 in Blackwater are a WIM franchise. I have used them but only for tyres. I would probably go to Chesham for alignment, TBH.

I have a matching set of tyres like yours


break me, camber is way off, and exactly matches the damage to the tyres.  This is the problem with people who don't know what they are doing.

I suggest a visit to WIM in Chesham, and when you book (booking is essential), mention OOF for our club discount (only available at Chesham)


No amount of tracking adjustments will cure that problem, no matter what garages say about 'within spec'

I am a little concerned that we are comparing apples with apples. I am quite happy to trot off to Chesham but am just checking whether there are any differences between the late model Elite V6 which has a "Sports Suspension" and earlier Elite models as VX are admant the camber setting is correct for my chassis number

The GM figures are wrong . Thats the issue. And that is what has ruined your tyres.

Been there myself, wrecking tyres in 6k, plenty on tread, but canvas on inner shoulder edge. Everyone failed to resolve it, except WIM.

Go to Wim.


 We've all been there and got the t shirt re tyre wear issues.

Car model makes no odds. Vx settings are so wide a tolerance as to be worse than useless. This whole story is as old as the hills.

Wim will account for set up for any sports suspension.

Std is -1.10.
Sports -1.20 maybe more depending.


Wim! Job done! Although get them to check bushes and ball joints etc just to be sure. Never trust a vx hoody!

The suggested GM settings work fine when the car is newish, as the suspension ages the coils become much more fluid thus adding dynamic gains to the camber position.

In addition the front camber tolerance is vast, oddly vast, so there's loads of opportunity for the final positions to be too deep if the technician only looks at the colours.

The front camber on the Omega is adjustable so all we are really interested in is the target position not the tolerance.

Years back i researched a new front camber position that would encompass most cars in the realm of "worn" suspension. After about a year the final position of -1 degree 10' with the car unladen worked.

The OEM suggestion is -1 degree 40' with 140kg added in the car. It could be said setting the chassis to -1 degree 10' unladen would be deeper than the 1 degree 40' loaded but this does not take into account the fluid dynamics on worn coils.

Hope that helps?

Thanks for all the input - I will have to make the Chesham trip
