If one wants to know what @gaijin says, one should ask @gaijin
First, there are several sizes of E-Rated KO2 tires that do not have a RCTIP of 35psi - see my signature for just one example. If someone wants the RCTIP for a specific size, then feel free to ask and I will respond.
Second, you are partially correct. No LT-Metric tire, regardless of Load Rating or size, should ever be run below 35psi at highway speeds.
I'm here to help - all one has to do is ask.

Well now I feel like an imbecile, considering I'm running the exact set up in your signature and still asked for RCTIP.

Hey, there is no such thing as a dumb question - I guess my answer to your post will be no surprise.

This forum is so great, everyone is so helpful!
@gaijin generally speaking for the same size tire (e.g., 285/70/R17), are P rated tires supposed to be at a higher or lower PSI than LT rated ones? I wonder if the added stiffness of E-rated tires is partially offset by the lower PSI they can run on. And perhaps most ride harshness complaints can be explained by people inflating their tires to the max 80psi.
UPDATE: I found my answer in the Toyo doc:
WARNING! Please note that size-for-size, LT-metric tires require higher air pressures to carry equivalent loads of P-metric tires and that any failure to adjust air pressure to achieve the vehicle’s load requirements will result in tire fatigue and eventual tire failure due to excessive heat build-up. Due to the higher PSI requirements of LT-metric tires they may not be suitable for replacing O.E. P-metric tires because of the ride harshness that results from higher PSI requirements.
So with P->LT you get both stiffer tires and higher PSI.

Yes, sorry. I should have been more explicit that I was referencing 35 PSI for my LT 285/75R17 121/118S E BFG KO2s on my YM LX. I know that the RCTIP for the same exact tire can be different even for the same YM LC and it is always best to confirm rather than guess, which is why I always @ you as I certainly don't want anyone taking my word for it

They look great on the white LC. Really slick. Of course it looks much better covered in a coat of dirt

OK, "generally speaking" (and I don't like to frame any statement with that caveat), P-Metric tires will have a lower RCTIP than an LT-Metric tire of the same size.
For example:
The RCTIP for LT285/70R17 tires on an LC200 is 40psi F/R.
The RCTIP for P285/70R17 tires on an LC200 is 27psi F/R
But the world is not made up of only P-Metric and LT-Metric tires, there are also ISO-Metric tires which come in two varieties - SL (Standard Load) and XL (Extra Load or Reinforced). These may also require different RCTIP for the same size tire, but one must also know the Load Index of the tire to accurately determine that.
For example:
The RCTIP for 285/70R17 SL 116 ISO-Metric tires on an LC200 is 33psi F/R.
The RCTIP for 285/70R17 XL 121 ISO-Metric tires on an LC200 is 32psi F/R.
Not a big difference in this last example, but does not diminish the point that it is always better to determine accurately The RCTIP for a specific tire/vehicle combination than just generalize (otherwise known as "guessing").

Sorry Dangcat. I’ve been slacking off lately. This is a shot from the wilds of the San Francisco peninsula which is the best I can do today. We are heading to the mountains next week so I should have some more aesthetically pleasing shots then
You need a hybrid badge on that thing driving around SF. That, or a “This vehicle runs on organic hydrocarbons” sticker of some sort.
Beautiful!!Sorry Dangcat. I’ve been slacking off lately. This is a shot from the wilds of the San Francisco peninsula which is the best I can do today. We are heading to the mountains next week so I should have some more aesthetically pleasing shots then

I don’t hold anyone’s past against them, so don’t worry. However, from here, if you want to keep this Doctor away, then it will cost ya a picture a day!
Also, remember, it’s not the LC that compliments the background, it’s the background that compliments the LC. If I wanted to see pictures of the SF peninsula, I’d go on google and search for SF peninsula.
No brother, we come here for the pictures of the LC, it’s really a different kind of beautiful, and could care less if it’s sitting in front of a Mountain or a Toilet; those are just distractions.
Mud, I need you to back me up here, Or else deal with my wrath for the days with no pics!
7/26: 33 minutes left until the day is over, still no sign of today’s picture. 32 now. Tick Tock.

I just realized my face is hurting from smiling the whole time reading this build. 1. It's freaking awesome, well done! 2. I'm purchasing my first LX tomorrow and the lack of mods that I have found have had me 2nd guessing my choice. After reading this, I can't wait to pick it up tomorrow and get after it! Thanks for sharing. Hopefully I can do the same here one day very soon.

Thanks, and welcome to the forum. I highly recommend the Official LX Pic thread as well. You should post as soon as you get shots of your new ride.
OK, so I saw a video on YouTube just now. Is it really as simple as loosening those screws and sliding them down? Does it increase full height or does it make the normal setting higher?
Hope you don’t mind me answering this for you.
It raises all settings by up to 1.25 inches, I have seen people report different numbers, but at least .5 inches for everyone. I made a quick video a while back to show people where to find the sensors.
If you want an additional .8 inch, then the car does have a “extra high mode”, achievable through messing with settings in techstrean. @radman has a write up thread on it. There is also a good thread on getting techstream up and running in 5 mins on here.

Ha! This is the exact video I just watched. Thank you! Does alignment need to be done after doing this?
small world, and my pleasure bud!
Yes, anytime you raise or mess with the geometry you do want to re-align it. I felt a difference right away.

Don't forget to zero point calibrate after as well. The dealer should do this with each alignment.
Zero Point Calibration
It's not talked about on this site, but it's a thing in almost all Toyota/Lexus models - zero point calibration. I have not researched this topic enough to understand it fully, but it's generally recommended after any sort of suspension, alignment, steering rack work, that a zero point...

I did not know! Thanks for this as I am sure firestone did not know either. Got myself a good read for later!Don't forget to zero point calibrate after as well. The dealer should do this with each alignment.
