Im new to this forum but I have been riding down in miami for a bit. Tire pressure is a sensitive subject. It has to do with a variety of things that deals with weight, climate and kind of tires. I ride with michilen pilot or pilot 2ct. I weigh around 150-165. I bring the pressure to 36f 36r check them every two weeks or if the bike rides different. Once your psi is set for you, you will know when it is off. When the tire is warm to the touch of your back hand it should be around 38 or 39 and when the tire cools it will drop down to about 36. If that helps.
