Front / Rear
30 PSI 35- Max
20 PSI 26- Economy. Which seems kinda low.
So if you are running say 30 PSI front and rear that translates to roughly 2.10 BAR

FYI: I've noticed...the higher the PSI/Bar....the more my kidneys scream at me!
The car is so light, I keep them at 28 front/26 rear.
My SRX weighs 2,000 more lbs....I keep them at 32 front 30 rear.

You could always chalk test them and dial in the perfect pressure.

Doorgunner gives good info.
if you give max permissable axle-weights and yourtire specifications this " pigheaded Dutch selfdeclared tyrepressure-specialist" will calculate highest pressure with still acceptable comfort and gripp, for fully loaded. And , because of the lightweight car with oversised tires, it will be in the 20 to 26 psi range.
in Europe official system, I once got hold of and went running with, gives 1.5 bar is 21 psi as lowest to go. But in time I concluded this was to prefent tires coming from rimm in curves, and nowadays most rimms have 2 humps to prevent that, so lower is to laws of nature possible.

I find with no power steering and the 454 in my '70 that the higher front tire pressure certainly helps to turn the wheel when below 5 mph!

Not sure what stock tires you have but for 225s, the door label shows:
Front / Rear
30 PSI 35- Max
20 PSI 26- Economy. Which seems kinda low.
So if you are running say 30 PSI front and rear that translates to roughly 2.10 BAR

I like to run my tires on the low side it helps the tires with bite on the launch. 5 psi seems to work good for me anything lower and he car gets squirrelly on the top end
