Your own placard is the authority. You will find it on the printed on the tyre sidewall, next to the pressure range. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tyre.
What changes on this bike
Both the derailleur Como 4.0 and the hub-gear Como 4.0 IGH use the Pathfinder Sport Reflect 650Bx2.3 front and rear, so one size covers the range.
The Como is the upright, step-through sibling of the Vado and carries a 27 kg-rated rear rack, fenders and lights as standard; a loaded rack plus rider is the case for keeping the tyres near the top of their 35-65 psi band.
Specialized gives only the inch size; 58-584 is the ETRTO conversion for a 2.3in 650B tyre, and the sidewall is the place to confirm it before buying a replacement.
