I am running GP 5000 tires with silica latex tubes. Measured installed width is 23 mm. weight 145lbs with approximately 20lbs of Trek Speed Concept.

I have been running 90lbs in front and rear in training on mixed surface but all good roads. I know this cannot be completely accurate but what ball park PSI would you suggest erring on the low side of the break point?

BTW... the mavic app says 107 front and 112 rear. Based on what I have read here, that is about 25 PSI too high
