UPDATE
Many thanks to all for the comments. I forked out £65 for a complete alignment.
The Toe was way out on the rear wheels. The spec is 0deg10 to 0deg20 and one was -0deg32 the other -0deg35.
There is an adjustment for toe which which the tyre specialists discovered when they were doing the job.
Thanks again to everyone.
Hi,
Can anyone help with the following problem on my 2.0L HDI 110.
New Pirelli P6000's have now done about 7000 miles and the rears now have 7mm tread on the outer edge and 3mm on the inner. The pressures are as per Peugeot.
Thanks.

Not sure if the 406's use the Stub Axle back system like the 306's... but looking from the rear are the wheels sloping inwards or outwards?
IE ... (excuse the drawing)
\---/ or /---\ not |---| ???

Hi, They sit very slightly /---\.
A bit more info.....The vehicle has done 80K, previous tyres did at least 20k (on the vehicle when I got it) 95% of my driving is Mway.
Thanks for helping, Malcolm

Well on my old 306 they sloped inwards...
Can you hear any rubbing when you corner hard (say around a roundabout or the like?)

Go to a good tyre place and get the geometry checked on all four wheels on one of those lasar things. The money it costs you will be easily saved in increased tyre life.
One of the rear wheels on my 406 estate was a mile out of line. It had done about 90k at the time and I recall it was toeing out very badly.

Assuming the 406 has the common trailing arm setup used on BX / Xantia / ZX etc it could be the trailing arm bearings. If it is bad enough to show uneven tyre wear then it will need complete new arms.
Adjusting the tracking will do no good without fixing the bearings.

It hasn't. 406 rear suspension is quite different.

Different to the 306 setup also?

I would say the rear tie bars are worn on this 406, Not unusual as the mileage gets higher, Have a look & stick a pair of new ones on, They are cheap & easy to do.
Also I only managed 6K miles out of 4 x Pirelli P6000s on my 405, I even swopped them front to rear. The Michelin Pilot Primacy tyres that I replaced them with last a good 25K miles & I dont hang about either.
The 406 uses a multi link rear suspension setup, Theres coil springs on the back too. Its not the normal torsion bar assembly like the older PSA cars.
