+1. I like to run mine as low as possible for a comfy ride without going so low that potholes and such will ruin my rim or cause snakebite on the tubes so at 200lbs I will usually run around 110psi. Obviously the OP could go lower being half of my less than svelte weight. If you like to use lower pressure just notice if it feels like your tire is bottoming out over bad road surfaces and add air as necessary. It takes getting a few miles in to find the sweetspot for yourself.
