I generally run mine at 32-34psi~ right in that range. Keep an eye on wear and adjust as needed. More air = more middle tire wear, less air = more outside edge wear. Also an alignment has to be kept up~

You'll want to keep the tire pressure at the car's recommended pressure which is usually located on a sticker inside the door jam. You do not want to exceed the posted tire pressure on the tires though.

i usually go at 34ish. higher tire pressure also yields better gas mileage - just dont go too high.

The PSI number listed on the side of the tires = the maximum pressure for the tires, not the recommended pressure for driving
For daily driving I run ~32 PSI, if I'm going to the track I drop the rears down to ~28 if I'm going to drive spiritedly on the street, I bump it up to 35 or 36 all 4

Different tires won't matter regarding the correct tire pressure unless you are running special tires or are filling them up to a specific pressure for performance. Just as long as you don't exceed the maximum tire pressure that's printed on the tirewall.
