Good numbers headed in right direction.
What... does the OP want.. ride comfort or "speed"? The latter is not increasing exponentially w high psi's... but the ride goes to hell.. see rough roads.
Depends on ride position.. more upright or how aggressive forward? Drop bar or ??
195 me... rear 60 front 48 Ultra ll's run TL. Mr Conti does NOT recommend that.. albeit works fine. Your weight w tubes... run same psi's range as mine. Yet.. you did not state tire brand.. another variable..........
Front sees load of around 34% of rear.. no need to run high psi to roll.. the 'pinch flat neurosis' only applies to actual flatting and failure to know when
your rubber is actually low prior to leaving.
