Bike Tire Pressure Calculator
The Bike Tire Pressure Calculator allows cyclists to find their ideal tire pressure based on terrain and riding conditions for the route ahead for mountain bikes, gravel bikes, and fat bikes.

There are three main tire pressure calculators that I use: Vittoria, Schwalbe, and Silca. They will all give you different results. Take the average. and fine tune to your liking. You may find that one of them hits it on the nose for you. Stick with that one.

These online pressure calculators are valuable tools. But while the OP wades through them, the simplest and safest approach is to read the min and max pressures directly off the tire sidewall and start with a pressure in between.
Like the OP perhaps, I ride my commuter mostly on smooth to rough pavement and hardpack. Its 2.3" hybrid tires call for 35 to 50 psi. I find a good compromise between comfort and rolling resistance at 40 psi.
This is largely a matter of taste on an ebike with ample battery range, so best to experiment.

If 30 psi isn't too far below the minimum pressure on the sidewall, it's probably OK. But if you run tubed tires well below the minimum, you're flirting with pinch flats.

imo... The calculators are a waste of time.
Start halfway between min/max stated on the tire and adjust from there to your own personal preference.
Increase pressure if tire feels squishy or not efficient
Lower pressure if ride feels harsh

have a related question, and I thing I know know the answer but-- should I have the bike on the ground and not on a bike carrier when pumping up the tires?
I know one thing I erred was the bike carrier has straps to go around the tire between the spikes , I was not thinking and left it tight then when pumping up the tire the strap would not allow the tire to fill. I had to use a tool to hit the catch to release it, too much tension for my hand!
The hand pump I have has the reversible head and I thought I had it correctly changed to Presta valve but it would not stay on the valve.

See if there is a ring around the pump head, and tighten it a bit, but not too much. Also the ones with the lever, some lock on by pressing down on the lever, and some work by pulling up on the lever.

It doesn't matter at all whether the bike is on the ground or in a rack. Obviously, you don't want straps around the tires. I would have deflated the tire, removed strap, then refilled the tire.
As for what pressure to use, I think it's more a matter of personal judgment than something to use a calculator for. Pick a mid-range pressure, try it, adjust as needed.
