Hi guys was just about to start a new post on tyre pressure and seen this thread, thought I would do a few checks today tyre pressure oil etc, on checking the rear tyres they were 51 psi, I am right in that they should be 37 psi on all tyres front and back and up to 41psi on rears if doing over 155mph lol, I have been driving around with massively over inflated rear tyres as I have presumed that the dealer I bought the car from would have checked them before driving the car 220 miles to deliver it. Just goes to show its wise to do your own checks.
