Um, well, uh see, I just, well I, I dunno.

I run mine 1 psi more in the front than the rear, (31/32) but I probably don't have to. The main reason I do is to compensate for the slight amount of weight bias that the engine has on the front end.
Plus the down force on the front end from aerodynamics.
Plus the weight transfer to the front wheels when you apply the brakes.
Plus the quicker response you get from the steering wheel.
Plus the cornering forces are greater on the front tires.
Plus running slightly lower pressures in the rear tires can USUALLY (not always) increase traction and acceleration.

There is probably a lot of testing that's been done, but the findings may not have a good effort-to-results ratio.

Plus I may be talking out my a$$. I could be totally wrong. I've never owned a car long enough to see what kind of wear patterns the tires had after running them that way. I average a car a year.

 

I run mine at 30psi and I get the correct tire wear. For a 245/50ZR16. This also seems to be the ideal tire pressure for performance.

 

I use 35psi front, 30psi rear on 235/50 R16 tires.

34 front / 29-30 rear with 245/50-15's on 15x8.5 rims on the Malibu (see sig). Tire wear is even with about 1/2* negative camber. I still corner it hard whenever the opportunity presents itself.

I run 37PSI in the front and 40PSI in the rear, the max PSI for my tires though is 52psi.

 

I put 36 all around. But when I SCCA race. I up all of them to 45. And when I drag race. I put 50 in the front and 30 or less in the back.

on the street i run 34psi in the front and 36psi in the rear on the track i run 60 psi in the front and 22-27psi in the rear. that is with slicks and front runners.
