"born yesterday"' 's answer was nonsense. That lift has inflated tires. I would imagine that it would need at least 100 PSI.
Phone a fork lift dealer or repair shop and ask them. Too high a pressure could be dangerous.
According to the chart on the link below, 150 psi sounds correct

A forklift uses solid tires which do not require inflation.
If someone has installed wheels with valve stems;
remove the wheels and examine both sides of the tire wall
closely.
Even a solid wheel will display a maximum load rating.
Verify the rating is adequate for your application.
If you have an inflatable tire, it must be marked for maximum
and minimum inflation pressure. If a valve stem is present
on the wheel, but the tire is unmarked; contact Nissan promptly.
There are two pressures to worry about. The max tire pressure and the optimal pressure recommended by the car maker.
As long as you are using the correct tires for your vehicle, you should be fine with the max tire pressure.
The pressure you want to use will be found on the label on the inside edge of the driver side door or in your cars manual.
about 60 psi
I have Nissan Forklift - 3 ton capacity Model No. - YG1F2A30U, i want to know how much air pressure suitable for that TIRE bacuase there is no writing any PSI.
