My tyres on the back seem to be wearing on the inside edge ,more than the rest. I suspect the camber is too far out, but I do know that Vauxhall set it like that for better handling, the question is - just how much should the wheels lean in? I suggest measurements at the rim, and please include wheel sizes. I haven't measured mine yet but am sure they are out. I have 16" Elite alloys on, and had the camber checked about two years ago, and have just replaced a broken spring, otherwise would not have noticed anything wrong.

You need the expertise of Tony (Wheels InMotion). You should visit his website http://www.wheels-inmotion.co.uk/ which is  very informative. Hopefully he'll see this post and advise you. You could also try sending him a PM.

He is THE top man for geometry matters.

I assume 0 degree would be dead straight for all the wheels,
On my Scoob I used to have all the wheels set at -1 degree, and what an amazing difference with the car that made, even with the four wheel drive I noticed the difference immediately.

BUT I guess that the wear on the inside edge is always going to happen over time, depending on how hard you drive the car, I used to change a set of tyres roughly every couple of years, which I didn't think was too bad.

Looking at my Omega, especially the rear wheels they look like they are also set around the -1 degree, I will probably do the fronts to -1 in the near future, especially as winter is on us!!!!!!!!!!!!!!!!!

I'm sure as mentioned earlier the expert will be along, but Agemo you didn't mention how long your tyres have been on your car?

Not entirely sure the rear camber is directly adjustable on Omega. Wheels-InMotion would know...

There is only one adjustment which sets toe but also has some effect on camber. Before taking it for a geometry check, have a good look at the rear tie rods and make sure that they are straight (can get bent if sliding into a kerb etc) and check the ball joint and bush. If OK free off the adjusters (lots of heat & force applied when in vice).

Thanx for the answers lads, mine are probably more than a degree out. The tie rods are straight. I will try Wheels in motion. It is interesting to note that the tie rods do toe-in, but have an affect on camber, Haynes just say rear camber IS adjustable, but of course would not dream of telling you how.

Yep, rear toe is adjustable with a small effect on camber....seem to recall the target camber setting for the front is -1deg 20sec

The broken spring explains the reason for the tyre wear as mechanical not geometrical.... Did you replace one or two coils?

Hello Wheels in motion, I was hoping you would read this. I appreciate your advice. Only one spring was broken, and the back of the car is now at the correct ride height, however the negative camber looks far too much to me. I have looked at the bushes, trailing arms, subframe, and everywhere else, and can't see any broken or bent components. I can supply pics if it will help.

I assume from your original post that both tyres are wearing? if yes then the broken spring would not be the criminal, although not entirely without blame. According to the data i have available your car has adjustable rear camber but i confess i have never had to adjust the rear camber on an Omega so i cannot validate the data. If you can make pictures available this would help since camber wear is very distinctive.
