This happened on my 2003 SRi DTi. Exactly as you describe. It was way before I got the car. I know the previous owner, just advised her to get two new rear tyres and an alignment check. Alignment was only millimetres out, this was sorted, and 21k miles later, the tyres are fine too

Also check the rear shockers and springs too

Make sure it is a full four wheel alignment check, that includes the rear camber
Have this performed at next tyre renewal

How long have the rear tyres been on the car?

Do have a rear knock?

I would like to thank all the contributors on the thread. Following your tips has helped me and I hope it may help other members with a similar problem to pass on how I got it sorted.
My model is a 1.9cdti 120 estate and the problem was - steering wheel off level - car pulling to the left - with uneven wear taking the inside edge tread off both front tyres and feathering on both rear tyres.

First the guys are right - don't waste your money a basic front wheel tracking at a tyre depot. Pay the extra and get a four wheel alignment with a specialist firm that use a 'Hunter' laser. My original Vauxhall springs had been replaced with Eibachs and being 30mm lower I was concerned about what settings they would use for the laser set up. But m8internet's technical know-how reassured me and just as he said the computer adopted the 'sport suspension' set up.

The diagnostic found my problem was caused by front wheels out on toe and rear wheels out on toe and camber. The reset to spec has given me a level steering wheel and a car that now drives to a straight line. The total cost was £80 but worth it for the transformation to the car's handling and hopefully I should save that with better tyre wear. Thanks again to all the members who share their technical knowledge on the forum.

yes my rear tyres wore down on the inside,, new rear upper control arms ,,,, sorted.

rear inner tyre wear is nearly always caused by rear upper control arms. Simple check to do and here is a video showing you http://www.youtube.com/watch?v=h-LF-qQY-Lc

There should be no movement when you do this check

Stand well back from the rear of the car, I wouldn't be surprised if the rear wheels have too much negative camber (wheels point in at the top).
