Tyre pressures

[stx133]

i have 225/40 tyres on my 540. currently running 36 psi all round. having issues with rear inside edge of tyres wearing prematurely.
options.
change pressure (up/down)
rebuild rear suspension to lift and try and reduce rear camber
accept the cost an enjoy the ride.

Im running 17 on my 95 540i with the suspension mods. The tires say 51 psi max pressure and that would be at full ride load. I have been running the air pressure 38 or 40 psi. The ride changes quite a bit to me between those two pressures. I think 40 is where I will be keeping it as it rides pretty darn good except for the worst roads, or the train tracks out here at least. I have been watching for tire wear and haven't seen anything as of yet. The tires only have about 4K miles on them but I would think if there was an issue it would be visible by now.

It isn't tire pressure
and probably not camber either.
