I agree with blindside, always a cold measure. You have to keep in mind when you run your tires for a while the increased heat will bump up the pressure about +2 psi. That is an average I have noticed in both my trucks even though they both have different brands of tires on them (both stock Bridgestone and Dunlops respectively). Even more so in hotter weather, especially up there in Sac. Invest in a good high quality tire pressure gauge and always keep it in the truck.
You may also want to inflate the spare to about 37 or so. Most people don't check their spare or forget to and when they need it, it's under pressure. Not something you want to find out on the side of the road. With it slightly over, it's easier to bleed it down than have to inflate it up. For me, I also carry a portable air compressor in case I want to air down for a beach visit and then air back up for pavement. An air compressor for your garage is also a great investment. No more waiting at the gas station for crappy broken air lines with inaccurate gauges.

You should check them when the tires are cold. I believe for every 10*F in temperature drop there's a 1psi drop. I've noticed a 1psi difference on the side in the sun when I have my cars parked on the driveway. This is after I just check the pressure before the sun got around to that side of the car.
Don't rely on the gauge built into the air chuck at the gas station. They're not very accurate. I also wouldn't rely on the pen types with a pop piece that has the PSI markings either.
Check your pressure with an accurate gauge when the tires are cold and make a note of the difference from the pressure you want to be at. When you get to the gas station check the pressure again and then the add the difference you got earlier when the tires were cold. (i.e., Cold pressure is 30psi, you want to be at 35psi. Now at the gas station you're at 33psi. Add 5psi of air, to 38psi.)

Ok, problem fellas...
After about 300 miles on the new tires, i got the tire pressure service light up on me...
I checked the air pressure, and i was still at 33 psi. Yet the light is still on. I don't know if i should inflate or what. The sidewall of the tire says the MAXIMUM psi is 35.
should i take my 4R to the dealer like the owner's manual says?

Will anyone see this old thread? How low
Seen many many comments on acceptable LOW tire pressure, for 17” tires.
My recently acquired 5th gen limited really likes to venture off-road. I have not been able to find lower advisable limits for the 20” standard 245x60 Michelin defender ltx ms or yoko geo lander 96 for any non-pavement use.
Since I will stay with this size, knowing how low psi can be used would be appreciated. Doubt you can go to 8 psi, but can or should you go to 18 psi?
Haven’t seen any sites address this. Surely others don’t mind getting these dirty.
Thanks.

What happens if it blinks for awhile then goes solid? And all tires are good to go pressure wise.
My assumption is bad sensor(s) but haven't had time to dig into it.

Most Likely a Bad Sensor when it goes Solid after Blinking. 99% of the time that's what it was

The best thing to do is experiment and find out. Your specific tires, weight of the rig and driving style all come into play.
I've seen guys run down to ten psi on non-beadlocked rims and have no issues, have also seen guys running twenty pounds consistently de-bead tires.
Losing a bead on the trail is just about expected in CERTAIN SITUATIONS and not that big a deal. A ratchet strap and decent air compressor will likely be enough to re set. If not there is always the old flammable aerosol can method, I'm a pretty big fan of that actually, kind of fun to fix things with fire.
Start airing down until you see sidewall deflection, check your psi, drive it and see what it does. Drop two psi and try again if you need more traction. You will probably damage the rims off road.
Thanks, appreciate the input. I will experiment. Just have seen virtually no info on the 20 inch tires specifically. Tons of input on 16 an 17 inch rim size, but nada on 20 inch 245x60. Wondering if any folks have any observations or experience about what psi you can go down to with the skinny Limited standard gen 5 tires and wheels.
