As others have said in past threads on this, it is a matter of driving habits, how you like your vehicle to ride, and the vehicle itself.
IMHO, relying on the door sticker PSI recommendation as the 'standard' or any tire you chose to mount on the vehicle, is not a 'rule' I chose to follow. How can one assume that the proper tire pressure for the Bridgestone H/T is the same for any other brand or tire type. Look at what happened with the Firestone/Explorer tire issue. The Ford thecommended tire pressures for the Explorer were chosen for vehicle ride reasons, not safety or tire wear. I'm not saying that Toyota is recommending a tire pressure that is unsafe, but it is only an average number, and can't possibly be correct for all tire types, and driving conditions. It is up to the user to do their homework, and come to a PSI setting that best meets the needs of the tire, and their driving style. Toyota knows that most users aren't going to take the time to do the homework, so they make an average choice for them. Hell, the average user probably doesn't know what their present tire pressure is, and most likely checks it less than twice a year.
I run my oem H/T's at 37, and my Revo's at 35. In my testing, I have found those numbers are the best settings for each tire, based on what I have determined for the vehicle handling control I prefer, and acceptable tire wear.
Others may find that a different number will work best for their situation, and that's fine. I just don't think the number on the door sticker should be touted as the 'holy grail', must be followed rule. end all answer.
