Around 70psi on the front and 72 at the back. Sometimes slightly less if I ride rough stuff like cobbles much.
Are you running tubeless ?
I'm using Vittoria Corsa tires with tubes & Rhinodillo liners
Vittoria Rubino Pro IV Graphene 2.0 Tire Set with Inner Tubes - Includes 2 Performance Road Bike Tires (700x25c)
I am at 100psi front & rear, mainly because I am heavy @ 167lbs & any lower psi results in pinch flats.
Other bikes in the house at the same psi are running Conti GP 5000
