I keep front and rear between 34 and 36 PSI. Currently running Metzler tires, which are rated at 44 PSI.

Also for every 10 degrees of tire temp change the PSI will increase or decrease approximately 1 PSI. So, if you add air to increase the tire pressure to 36 PSI, and the tire temp is 80 degrees. Then you go for a long hard ride and the tire temp goes up to 100 degrees, the corresponding tire pressure should be approximately 38 PSI.
