I recently switched over to Michelin PR4's and was hoping that I could get some advice about tire pressures. Michelin recommends 2.5 Bar front and back which is 36 PSI. They seem a little rough on some of the sharper bumps and was considering lowering the front down to around 32 PSI. I'm slightly nervous about overworking the front tire. My DVT is my first non-sport bike and this thing is a little porky. On previous bikes I wouldn't even think twice about it as I have always had good luck running lower pressures on Michelins.
