I am heading out for my first short tour wednesday 550 miles. I mainly been using my bike for commuting. I am using 32mm Vittoria Randonneur Cross Pro at around 85-95 PSI for commuting. Two fully loaded panniers weight 12 lbs each plus handlebar bag at 3.5 lbs and I weight 175 lbs.
Should I up the PSI fully loaded or just go by feel?
