tire pressure recommendations for these

I pretty much always run them lower than what one would consider normal, especially on the back but then I watch the tread wear as time goes by and adjust it so the tread is wearing evenly across the tire.
Worn more in the center means too much pressure, and more wear on the edges means not enough.
That usually ends up around 30-35 in the fronts and 30 in the rear because the rear end is lighter than the front.
