All that effort for nothing... you should've known better than to expect most the people on this forum to look at a nice spreadsheet when they can just ask and have someone answer lol.

If you mean the Cooper Discoverer S/T Maxx LT305/60R18 121/118Q Load Range E tire, then:
The RCTIP for those LT305/60R18 tires on your LC200 is 41psi F/R.

Hi Gaijin! thank you so much in advance for all of your help.
Forgive me if this question has already been asked but I didn't see my tire + vehicle setup mentioned. If I should be looking somewhere specific for this information to, happy to be redirected.
I have Toyo Open Country AT3 LT275/70/18 125/122S on 2008 LX570. What should my cold tire pressure be? 41 as well? Also not sure if this makes a difference. It's currently running on LC200 suspension, not AHC.
Thanks a bunch in advance and your continued contribution to help us newbies and more seasoned folk with your expertise.
36 PSI for a LX and that tire size, but since you don’t have stock suspension, Im not qualified to make a good recommendation.

Given your unusual circumstances, I would suggest you run a Cold Tire Pressure of 41psi - better safe than sorry, eh?

Hah, absolutely yes. Better safe than sorry. That's great that's what I kind of guessed but I'd rather lean on the experts.
Thanks again!
Thanks for providing your insights as well lx200inAR! For my own learning/understanding. Why would the LX with AHC take a lower PSI? I would have assumed the opposite, higher since in theory or at least in my mind AHC could accommodate a stiffer ride but that may have nothing to do with it lol.
I run an odd size tire. Dug around some and found a 'rule of thumb', which is temperature based. Increase your 'cold' pressure until your 'hot' pressure is 10% more. That is the minimum cold pressure you can run. Since the TPMS reports relative pressures pretty repeatably, it only takes a few days of experimentation to find the floor. After that season with pressure until you like the ride.
For me 35 psi is the floor based on load rating. 36 or 37 is the floor based on tire psi change, and 37 is where it rides best.
All provisios and at your own risks apply.

LC200 4.7 Petrol with AHC, 2008.
I have BlackBear AT2 LT 3PMSF 285/55R20 117/114S. What should my cold tire pressure be? Thanks
Please post a picture of the door stickers that show the stock tire size and inflation pressure as well as GVWR, GAWR (GVM) numbers.
That should give us enough info to make a valid recommendation.

Got it!
The RCTIP for those LT285/55R20 tires on your LC200 is 45psi F/R.
Thanks for the interesting question!

Thank you so much, have a great one!
VERY helpful -- thank you gaijin. And, thanks for all of the Mud members you've helped over the years. This thread is such a great resource.
I'm a little embarrassed that this is my 2nd post on Mud after 3 LC 200s and years of lurking. This thread pulled me in. I've officially joined the cult.
I think what your saying makes perfect sense. So that and 5 bucks and you can get coffee at the little window.
Do people realize that correct air pressure is not one fixed psi ? It depends on your terrain and even more the vehicle loading and in many cases the skill level of the driver.

Can I assume that the RCTIP for the LT285/65R18E Bridgestone A/T Revo 3 tires on my stock 2019 is also 42psi F/R?
Road tripping next week and will be hitting some logging/rutted roads where we're going. Is 42psi best for that? Should I air down some then go back to 42 for highway?
Thanks for this all this amazing help, great thread.
