Hey guys does a car have to be on an even, flat level when checking tire pressure, or is it independent of the weight distribution?

It's just that I don't have an even driveway (live on a hill), so I am wondering if I can trust the gauge readings.

From my little work experience at Sears auto center I remember hearing it should be on as level ground as possible. I might be mistaken, though.

I would say pretty even, as long as the hill is flat so that no tires are on a big bumps I would say safe but who knows.

hmm that was my thinking but a guy on a different forum said:
"Maybe this will help. I was checking the air in my tires today and just did a test for you. I set the front tires on my Silverado at 45psi this morning using an Accutire MS-5510B tire gauge.
I went out, jacked one tire up, and checked it again and got 45.2psi The sun is currently shining on the tires when it wasn't this morning so I think thats where the extra .2psi came from.
Either way I basically got the same reading with/without load so it shouldn't matter how its parked."

its not going to make a huge difference if you can't get to a level surface. But, a good solution is to take a jack, and jack one tire up then fill.
