I have a set of wheels with these rims and utlegra hubs 32 hole. I like the rims 23 25 mm profile. As usual when I got them I did do a quick go around to make sure spoke tension ok. So after maybe 2300 miles they are doing great. My question is maybe I can ride at lower PSI and I don't give it a chance.

I run these at about 100 psi on the rear and maybe 93 ish on the front. No pinch flats I am 6'1 and about 170 pounds. What PSI would you ride these at? Sure I could just keep dropping the psi in till I go overboard but now another question.

I run Conti PR 4000 II 23mm presently. I am an old school mind and the 25 just don't want to stick in my brain. Since I am due for a new set of tires should I go 25 they seem to inflate pretty close to the stated width. Then could I get even lower PSI and be better of than the 23's. I am I trying to split hairs and it does not matter. I do like a smooth ride but of course speed always in the back of my mind hate to ride slow if I can go faster.

Which rim? Archetype? 23mm width? 80 PSI would be plenty for you. HED would recommend 70-80 psi for your weight on a Plus (25mm) rim with 23mm tires.. Not much info on H Plus Son site. HED has maximum inflation on the Ardennes Plus of 90psi and minimum 23mm tire size. For the same rim in the 23mm size, they limit inflation to 100psi. Low pressure seems to be the flavor of the week.
