Okay, about what I figured. If one does lower the pressure significantly, some have mentioned the TPMS light coming on every time the truck is started and one must manually click that off. The question I have...if there is a failure, will the TPMS still notify the driver even though it was shut off at startup.
A small light stays on even after the larger alert is cleared. At start up you are just acknowledging the message by pressing ok, it isn't necessarily turning off future alerts. Not sure what kind of failure it would alert to anyway.
You can lower the pressures approximately 20% bellow what the sticker says before the light will come on. So in the rear, with a suggested 80psi, somewhere around 64 is where it might come on.
I have been running 60 front and 50 rear on tremor tires 285/75-18. I have almost 20k on these Duratracs and they are wearing nice and even. If you get the ForScan adapter and download the program to your laptop you can go in and change the TPMS settings. I and many others have done so. I think I set mine at 45 fr and 40 rr. The TPMS warning light will still function normally should the pressure drop below the settings. Leaving 70-80 psi in the rears kills the ride if the truck is empty.

You should just adjust it. Tire shops can do it. Call around. My 2013 f250 came with 80psi rear and I changed to a higher rated tire and run them at 53 and a tire shop set that for me. No issues as it doesn’t gooseneck haul or anything.
I plan to set my dually rears at 44 and run 40 as I want it to warn me quicker when the psi drops in the rear as these aluminum rims leak.

Not sure on the tire squat/bulge on rear daul but keep an eye on spacing so not to get tire rub. Something to think about.
I'm talking about the gap between the 2 rear tires as you air down it could close the space. I don't air down so don't know if at a low pressure you might run at will do this. Just something to be aware of.

This is an excellent point and those with DRW should also keep and eye, and feel, out for foreign debris that can get stuck between the duals. It happens and lower pressures may make it easier to get debris stuck in there.
