Yeah I ran it with 40 as recommended by the service department and tyre shops. I suppose it allows for fluctuations in tyre pressure as the tyre heats and cools.

At first I ran my 18s Dunlop Sp9000s at 34psi, they started wearing slightly on the outside, then I bumped it up to 40psi as recommended by my tyre dealer, and they wore badly on the inside, especially the rears. Now running 37-38psi. So far so good. But if you push your car fairly hard through corners, closer to 40 is supposed to be better, but my car gets alot of normal daily driving..

40 is fine on the front, but will wear out the middle of your rears quicker.

Run 36 or 37 on your rears.

I run 39/36 day to day driving, 41/37 for a twisty drive, and 50/45 on the track.
