Make and model tire makes no difference to the responses here. Every LT285/70R17 tire in any load is the same for the 200.
edit, going to add this to the post to add some more data so people don’t think I’m saying every tire with 285/70r17 has the same RCTIP.
the details do matter on whether it is a P Metric, LT Metric, or ISO Metric (Load index rather than size is what matters) tire. There is a table starting at that post with most every size tire for LC and LX.

Pretty sure it's been answered but couldn't find it what is the recommended pressure for the 285/70R17 on a LX570 ?

Link to very handy tire pressure calculator when changing tire size and type....

@gaijin I’ve run my tires per this table for a couple years now, just switched to 295/70R18s that will run at 35PSI. However, do you (or anyone really) have a general rule of thumb for airing down? IE what percentage of normal operating pressure, or a certain number of PSI to start with? Somewhat new to trails requiring airing down, and have just dropped pressure by 10PSI with ok results, not sure if there’s better wisdom here.
Edit: I’m probably overthinking it.

One good rule of thumb is to air down to 1/2 the RCTIP (Recommended Cold Tire Inflation Pressure) and then fine tune from there based on terrain, speed, etc.

Appreciate the guidance, will start there going forward.
If pulling a weight-distributed 5,000 lb trailer, would you recommend upping the PSI a bit?
My LX manual recommends adding 2-6 PSI (depending on which OE tires it came with) to the rear when towing. I don’t have an LC Manila to compare but you might look in yours. It won’t hurt you at all to add a few pounds.

LC200 or LX570? What model year? Petrol or diesel?
Oh I didn’t know all that was needed. It’s a Gx460, Gasoline

Sorry, I can only help with LC200/LX570 models.
You can always find the RCTIP yourself by using the calculator link posted above by @brian az :

Or you can learn all about it by reading an excellent monograph published by Toyo Tires found here:
