just keep experimenting until u find one that you like.. its also high dependant on the tire and the tire model and tire manufacturer as well i would say
just bring a tire gauge and drive around for aweek and keep on tweaking

It also depends on the size of your rims/tires.
If you're running a REALLY big rim, like 19s, you would want to maintain a higher tire pressure (closer to maximum) while w/ the stock rims, you can maintain a pressure close to 32 to 34.
The risk of overinflating tires are:
lack of proper tire contact to the ground, resulting in loss of traction and tire wear closer to the center of your wheels.
The risk of underinflated tires are:
Increased probability of actually denting your rim when encountering potholes. Actually driving on the sidewalls of your tires.
Improperly inflated tires all result in poor fuel economy and will exhibit less than ideal handling.

I use 30 all around.
I figure since the weight balance is almost exactly 50/50 the pressure should stay the same all around.
However perhaps 30 is low & I should try 32 instead?

Recommended tire pressures for stock wheels should be listed on a label in the drivers side door jam. If not, try looking in the drivers manual, there may be something in there. The tires manufacturer may also have a web site with suggested pressures for that specific tire.

I own ES100s and the are rated at 44psi max. I keep them at 40 psi in the summer and 35-37 in the rainy season. This helps wet weather traction. Not sure if 40psi is too high, but I know every tire shop only inflates the tires to 35 psi. I think that was under inflated in some tires. When I run lower pressure in my tires I can feel the side walls or "roll" my and ealier then with higher psi. I don't know if 40 is too much but it is not over the manf. recommended psi.

P.S. I run equal pressure on all four. And the stock tire presures in the door are thrown out once you replace them with non stock tires. I would think the higher tire pressure would yeild better gas mileage and a low one like 30 may harm gas mileage.
