RedWhite, sorry, I did not mean to imply that the reduced weight had something to do with the overinflation. I was actually applauding you because the two together are more energy efficient for saving fuel. Less weight and less rolling resistence means better fuel economy. The downside to overinflation is the bumpy ride because you get no flex in the tire sides (especially if you have low profiles).
Take a look at tirerack.com. Everyone really likes these tires (as they rate them on tirerack). The tires are very cheap, and really good (and they come in a lot of sizes). Also check out some of the threads here on the GEs.
Good luck with your next set of tires.

I run 30lbs cold air pressure in my front and 32 cold air pressure in my rears on my 2004 e60 530i, and my Bridgstones are wearing even, so far!! Hope this helps...

Do you have the sport package?
I have to think 30 front and 32 rear is much to low especially if you have sport package. They recomend 32 and 36 with sport package plus run flats. Run flats are stiffer and they tuned and recomended pressure based on this so 32 and 36 is already on the soft side for a regular tire.
If you have non-run flats and a sport package I guess lower pressure will give you a comfy ride but I would think the tires would feel a bit soft-I guess depends on what kind of driving you do but to save my tires I may try that! thanks

From: Europe, Netherlands, Near the (German) Autobahn
My Ride: 525d E60
checked my tyres today:
front 2.3 left was fine, right had lost .2
rear 2.6 both fine.
front tyres will be replaced next week, will ask if worn wrongly (other than the sides being 'chipped') and if what you mention is a know issue here (Netherlands)
100 lbs (is 50 kg right?) won't make a difference, even your fuel tank full or empty is more than that.
but from the above, should I conclude that ROF (run-on-flat) tyres on big wheels (17") should be driven with lower pressures if comfort is required?
I find them very uncomfortable to drive: hard on bumps and very sensible to (whatever you call those ruts in the road caused by trucks). But cannot compare the same car on non-ROF's only different cars.
