While I don't agree with/believe this generalisation, I did note that last time I changed the tyres on our Merc ML430 the tyre fitters (a large national chain in Australia) inflated the tyres to about 38 PSI, they said the tyres would last longer. However the ride was too hard so I deflated them to about 30 psi.
Mercedes recommend 29 psi, but that is for the tyres that were fitted to the car when it was new.
Back to camber on the 411. The 411 was originally set up with zero camber and generally speaking it is not adjustable. At least not without disassembly of the front suspension and drilling new holes for the fulcrum brackets, which are bolted to the front crossmember and govern the camber. Castor is 1 degree and "toe in" one eight of an inch.
Janne, I suggest you get the front suspension geometry checked. Tyre fitters should have the equipment to do it.
If the camber is wrong, it's possible that some of the suspension bushes are badly worn, or perhaps the front suspension has been dismantled previously and the wishbone arms have been swapped around (that is assuming the wishbone arms are not exactly the same). The latter is a bit of a long shot, but when I disassembled mine Brian Marelli advised me to mark all the components so that all the wishbone arms etc were put back in exactly the same position.
Unfortunately it's difficult to determine the condition of the front suspension bushes without dismantling the suspension!
