I'm surprised your max inflation pressure is only 40 psi. What type of tires are these? My Goodyear LS2 runflats need 50psi to get the advertised load rating. My non-runflats on other Bimmers are in the mid 40's. I run fronts at 40 and rears at 36 on the X5. Outside edge wear has all but disappeared.

I was wrong, when I looked at my tires this morning it says 50 psi max. Not sure where I got 40 psi
They are Pirelli SCORPION VERDE ALL SEASON RUN FLAT 255/50R19 107H XL. I just looked them up in Tirerack and here what it says:
"XL/RF tires required if 255/50-19 is used on rear axle. This requires higher tire pressure levels of 42psi for proper load."
I inflated to 40 psi all around this morning, should I go with 42 in the rear?
