The one thing that hasn't been mentioned is that every vehicle has a vehicle tire placard that lists the original tire size and the proper pressure for that size. If you are using the tire size listed there, then that pressure has been tested by the vehicle manufacturer.
Personally, I think that is the correct pressure to use - unless there is a specific reason to deviate from that.
That's true and usually good advice. However there are other factors. The tires themselves for example. A deviation from OEM tires may not give you the same results, even at the same tire size. I put Firestone Destination LE tires on my Trailblazer. The first thing I noticed was that my mileage dropped, until I put 3 extra PSI in them. OEM pressure in the door is 30 front, 35 rear. With our new HTT I have to run 40psi in the rear and 35 in front. It made a huge difference in the towing experience and in towing mileage.
True, but you have a Trailblazer. Just as when I used a Suburban, I weighed my truck and adjusted my tire pressures according to the weight at the axles. The suburban was 32 all around, but the tires would squat a lot, which would be dangerous for stability and a possible blow out.
