Kenda Booster 700x45c OEM tires that came with the Scott hybrid bike. Note this is not Booster Pro and I cannot find link to this anywhere. Printed on the tires are 45 min - 60 max psi.
Kenda K935 700x40c cheap replacement tires. Printed on the tires are 50 min - 85 max psi. https://www.amazon.com/Kenda-K935-Kh.../dp/B01LW99YYX
Schwalbe Road Cruiser K-Guard 700x32c. Website lists max and min pressure. 65 min - 95 max psi. https://www.schwalbetires.com/Road-Cruiser-11101273

(Edit: had to correct Schwalbe link as there are many sizes on that same page)

I used your tire info and the Silca calculator, making some reasonable assumptions for the input fields the calculator requires, and indeed, the pressures suggested by the calculator are 15-25% lower than the minimum pressure listed on your tires. If I were you I’d inflate the tires to the minimum pressure listed on the tires, or slightly higher, and call it a day.
