What are other 991 GTS owners running on their 20" 245/305 PZero's for DD use?
I have backed mine off of the recommendation on the door sill to 32psi front and 41psi rear.

I think for as long as I have had a Porsche I have always driven them 32/38 cold.

But not all 991s have a 305 rear tire. And certain wheels like the Sport Techno get 'em. The wide body gets the 305 too.

If I prefer a firmer ride, would the recommendation be to de-select "Comfort pressure" and fill the tires closer to the door sill recommendation? I ran them today at 32/38 cold and it was fine, but I could possibly stand an even a firmer ride. I can obviously play around with it, but was curious what others have experimented with. I suppose I can leave the pressure at 32/38 and then select the PDCC button (although my car does not have PDCC).

Those are full load condition pressures. Read your manual for partial load pressures, and "comfort" pressures.

I have them at 34f/43r what is what the manual says for comfort. Though seems high for the rear ones. Have not tried any other pressures though. Want a comfort ride and make the tires last at least till 15k miles.

You might want to check your manual again. I don't think the comfort settings are anywhere near that high.
