I find the KO3 in an LT-Metric size LT285/60R18 118/115S Load Range D.
If that is your tire, then the RCTIP (Recommended Cold* Tire Inflation Pressure) for those LT285/60R18 tires on your LC200 is 46psi F/R.
* According to Toyota:
Tire Pressure vs. Tire Temperature
Tire temperature is dependent on “cold” tire pressure, driving distance and speed, ambient temperature and road surface temperature. As the temperature of the tire changes, air in the tire expands and contracts, changing the tire’s air pressure. The cold tire pressure for all Toyota models will vary and will need to be adjusted accordingly.
“Cold” tire pressure, as shown on the tire pressure label on our vehicles, is generally considered to be the pressure in a tire that has not been driven in the past 4 hours and has been parked outdoors.
And don't forget to re-initialize your TPMS system.
