this is more complicated than just using whats inside the door. it depends on your tires, how much cargo/people travel with you, how you drive...etc.
Some tires are designed to work on 35psi max cold (anything BFG for example), others are high as 44psi cold (Dunlop A2's, many bridgestones). With a 35 pound tire you are probably safe to go as low as 30...you could maybe go a pound or two lower in the back cause there is less weight on them. With a 44 pound tire probably 38-40 is minimum...I run my A2's at 42psi all around....the ride isn't bad either because the tire has a soft sidewall design. the Bridgestones on my truck are the same way...they actually ride better at 44 pounds than my BFG's did at 33-35 and get better mileage.
if your vehicle is loaded up with people or cargo you should fill the tires up closer to their rating. The tire will last its longest and work its best when at its max pressure, but the ride may suffer....lower pressures in a tire cycles the steel belts in the tires more and can cause failures....ie: firestone/explorer.

Was using 32-33 psi all around and have found that the ride is too harsh and causes vibration at high speeds. Reduced psi to manufacturer's recommended 29 psi all around and found the ride to be much more comfortable, controlled, and less shimmy at high speeds. I was also told by a friend who worked for Firestone/Bridgestone as one of their top salesman that you always go with the automobile manufacturer's recommended psi, as this ensures the best ride possible.

WHAT?
after this I went and check the pressure on mine and I have 45f and 35r is that OK? the tires are the ones STOCK I recently got my MAX so I just found out about this --- I ride alone all the time every now and then someone is in the passanger but that's about it.
Should I lower the pressure to 29 all around?

Yup. 37 up front to give good enhanced road feel. 32 in back because there's not too much weight back there, and the lower rear pressure helps keep the back planted, like a mini RSB effect.
