You can google and find the install sheet for the RW wheels. Toyota recommends 46 psi for these wheels and 285/70R17 tires. I bought a set of new RW wheels for my 2019 200 and that’s what it said. 46psi.

RW 46psi.
It’s been addressed on here multiple times, but Toyota’s stated 46 PSI is actually incorrect.

Okay, my turn. Whats the recommended cold psi for BFG AT T/A KO2 LT285/70/R17 on a 17x8.5 wheel? I'm currently running 38psi cold.

And that install sheet is wrong. The correct Recommended Cold Tire INflation Pressure for LT285/70R17 tires on a LC200 is 40psi F/R.
Here is a link to the original install sheet: Original TRD 17" Install Sheet
Please note on page 5 of 12 the recommended cold tire inflation pressure is 40psi F/R.
Toyota later determined that since the TPMS sensors will not trigger a low pressure warning until the set pressure had decreased by 25%, this recommended inflation pressure could allow the tires to run at 30psi before a TPMS warning which might be interpreted as a violation of FMVSS (Federal Motor Vehicle Safety Standards) which require a minimum allowable inflation pressure of 35psi for LT-Metric tires.
To avoid potential fines and possible litigation, Toyota changed the recommended cold tire inflation pressure to 46psi. Here is a link to the revised install sheet that reflects this change on page 5 of 12: Revised TRD 17" Install Sheet
This revised pressure of 46psi results in a TPMS low warning trigger pressure of 35psi which is consistent with FMVSS minimum requirement of 35psi.
Thus, 46psi is not a "correct" pressure, it is a "CYA" pressure.
Run whatever you want. Believe whatever source you want. But 40psi is the pressure that yields the performance designed into the LC200.

Very cool thread. I think I learned something. Using that Toyo tires link I cross checked my FJC's stock load rating per the 32PSI door sticker at 2425, and then checking the LT tables for my 295/75/16s I need to fill them to 40PSI to be properly inflated (2460). I think they are down at 33 at the moment....

Sorry, @grinchy - I have nothing for you; can't find that size anywhere in the published Load/Inflation charts. I purchase new Yearbooks from the TRA (Tire and Rim Association) every 3 years, so my latest is 2017 - maybe it will be in the 2020 Yearbook.
As an aside, when I hear "200 series" I take that to mean either a LC200 or LX570. The LC200 is URJ200 and the LX570 is URJ201 - both in the 200 series (200, 201). Since RCTIP's are different for a LC200 and an LX570, it is helpful to be specific about which we are talking about. No bearing on this case, however - just FYI.

That's great...appreciate the rapid response, expert explanations and walking through the calculations in previous posts. Thank you!

Well, I must congratulate you on finding a way to force me to make a pressure recommendation for something other than a LC200/LX570 - warning to others: this will not happen again.
I think you are misreading/misusing the charts. Your stock tires are P265/70R17 113S @ 32psi which equals 2425 lbs. So far so good.
For an LT-Metric tire, you must divide 2424 by 1.1 to compensate for the different construction, 2424/1.1=2204 lbs.
When we look this up in the tables, we find the Recommended Cold Tire Inflation Pressure for the LT295/75R16 tires on your FJ Cruiser is 35psi F/R.
BTW, 35psi is the MINIMUM recommended pressure for ANY LT-Metric tire on any vehicle.

Ahha. I guess if the 1.1 thing was in the Toyo article I totally missed it. Good info!. Ill add a few lbs to them!
It's an LX 570. I'll look for another size in 129q and try that inflation.
295/70r18 nitto ridge grappler are 129q.

That's the outdated(2015) version of the tables published by Toyo.
Here's the link for the 2017 version which I have referenced many times: 2017 Toyo Tables
