tire pressure

[Jayeffel]

It has been a while since I rode my Giant e-bike and seeking info on what tire pressure would be best for regulars roads and hard ground rail trails. Right now at 30 psi,

Depends.

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.

thanks, the electric air ump I have only goes to 30 lb psi I think, have a hand pump that will not stay on the valve. So stuck at 30 psi now, I think max is 60 psi on the tire.

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

45 psi is about right for that bike. Every month it will drop to about 41 so pump it up. The 30-day average will about 43. Get a new pump or just the pump head.
