There are pictures that show three different versions of the b-pillar sticker. 19" specs are given on two of them, but I'm not sure the size is that same as what you're running...

I put 32F/35R.
For staggered 18 RFTs (550) they are:
Below 100mph
All loads - 30F/35R
Above 100mph
Light load - 29F/32R
Heavy load - 33F/38R
Yeah, right. Say I am about to get into a race with that punk in G35 coupe. What I am supposed to do? Tell him ?wait for a second I need to let some air out of my tires to go faster than 100 mph??
To be serious though, the above advice is controversial. Before BMW suggested higher pressure for higher load. Now it is the same pressure for speeds below 100mph but if you want to drive faster you should add/loose air based on load. Does not make much sense to me. Also the new numbers are much lower than 2005 545 numbers. Plus I just can't stand softer tires. With all that said I use 38F/40R.

For my 2007 550 I decided to ignore BMW suggestions for tires pressure. Their recommendations are very confusing to say the least.

Above 100mph

1. Off AC
2. Off DSC/DTC
3. D->DS if you have steptronic
4. now one more step lower tire pressure.
I don't know if your opponent will wait for you....
