Rear Tyres Wearing on Inside Shoulder
Has anyone experienced their rear tyres wearing on the inside shoulder ?.
The car has had an easy 76,000km so it is not suspension wear.
The boot has some weight in it at times but not over loaded.
Majority of use is on the freeway.
We have half a mile of steep loose sharp blue metal ( basalt) track to the house so some slight scratching occurs.
I am a conservative driver at roundabouts & corners. ( not always the case) so outer shoulders not worn.
The last camber readings were left -1' 27 .right -1'13. I believe the target data is 0' 30 .I think the car has too much negative camber.
The ER 300 OEM Bridgestone's disintegrate , with severe cracking on the inner shoulder with at least 3/32 ' wear left above the wear limit.
There is no camber adjustment available ,just toe in.
I wonder whether my driving style & driving conditions exacerbate the problem ?
Comments & ideas welcome.

John, Benz at one time had some fluted bolts & 3 way bushes for the rear camber arm similar to front. They are as rare as rocking horse crap.
On stock cars if the rear toe is correctly set then it is usually a sign of bush wear on the top camber arm. If new bushes don't resolve then there are easy aftermarket solutions. Adjustable camber arms (only really needed if lowered) or KMac makes ecentric bush/bolt arrangements that make for easy adjustment.

K-MAC manufacture front Camber and Caster kits and rear Camber and Toe adjuster kits to properly compensate for premature edge tire wear and improve traction. Currently front and rear Toe only adjustment is available OEM on virtually all Mercedes models.

At US$450 for a rear set they sound very expensive.

I was looking at the Renntech site and theirs is almost $1400!
At K-Mac you'll find a product with years of background and many satisfied customers ready to verify they work as promised.
Not much for your Peugeot, however...
