for non-paved roads...
Here is the best way to determine YOUR pressure...forget the gauge:
Find a smooth level part of the road that you are comfortable to stop in for about 10 minutes. Use a nail, a knife, or a fingernail clipper to let out the air from the four tires.
Stop letting air out when you see the sidewalls START to bulge, and when you can shove the tire inwards with the palm of your hand. If you are able to push in the sidewall some, you have reached the correct pressure for your vehicle. Could be 12, 15, 18, of 20 psi. Any more than 20 is too much (unless you are driving a four ton truck with dualies). Use the gauge if you wish after the first tire, but I'll bet you that if you use the same technique on all four tires, you'll be within a pound or two between all the tires.
