I run 35psi all around, COLD pressure. Yields even wear and good MPG. When I got my 530i the rear tires were wearing the center heavily. Due to the high placard pressure of like 41. So that confirmed my thoughts of 41 being too high for a unloaded average driving vehicle. I put 82k on the factory cheap tiger paw tires on my company work car. Pontiac G6. It called for 32psi, I ran 35 rotated every 10k at oil changes. At 82k I was just hitting the wear indicators. All 4 tires were wearing even and flat. I had/have same excellent results with 35psi on my Lincoln MKZ (sold), 335i and wife's C300. I manage to get about 80-110k out of a set of tires on any vehicle I look after.
