Tyre pressures
Two days after I got my car, I checked the tyre-pressures. It was on the weekend (ie. very warm) but still the 4 teres returned 28psi forst thing in the morning. No wonder my tyrers felt like they are scrubbing hard on the front when pushed into a corner. I have raised them to 36psi (cold) all around and will see how it goes.
Anyone tried staggered pressures (ie. more/less pressure at the front/back)? I had staggered pressures on the MR2 as it has more weight in the rear, but also on the S2000 (even though it has 50/50 weight distribution) as the fronts required +3psi over the back to balance the car (to my liking).

To be honest, I havent played around with my pressures at all. I set them at 36 front and back and that's where I've left them.
The only time I will probably ever adjust them is when I go to the track and I might drop them 3 - 4 PSI.
BTW the tyre plackard (under console lid) states 35 PSI front and rear.
As always

I'm not sure if you just wrote that wrong, but for the track you usually increase the pressures. I usually go on the track with 35 - 40psi in the tyres. I would not recommend any less than 35psi with road-spec tyres. Part of the reason is that with less pressures you will overheat them more (and road tyres don't have much grip when overheated ... which is not hard to do on the track). The other reason (and to a degree more important) is that with low pressures you are running a risk of stripping the tyres of the rim ... whether it is when cornering hard, sliding or actually sliding off/on the road.
ps. When you do an advanced driving or racing course, then the instructors will usually tell you to pump up the tyres to 50psi. Though, good cars with good rims/tyres will be very happy in the 35 - 40psi range.
