2022 F250 TPMS Low pressure trigger
Does anyone know how low you can go on the tire pressure for a 2022 F250 before the TPMS triggers an alert for low pressure? Factory recommendation is 60 psi front/65 psi rear. I would like to go 55 psi front/60 psi rear. Thanks!

I want to say they trip at 15 or 20% below the value on your door sticker or something to that effect. You can adjust the values with Forscan. I'm sure the real answer is in a thread here on the forum but you get the idea. I run mine at 60 and used Forscan, my sticker is 75F 80R

Just had a screw go into my rear tire and I wasn't getting any warning while driving my truck, when I got into it the next day, the warning was flashing 38 Psi, from 80 Psi. It seemed to be loosing a Psi an Hr. while I was driving it the next day...

My 22 F250 XLT is rated the same as yours. I have ran mine in the low 50's without any warning light coming on. Currently mine are 54 all around.

less than 80% of the target value is when the light will come on.
When I'm not towing, I run set the tires at 50. I used forscan to set the new target value from 65 to 50.

Why not just lower the pressure in one tire and see when the warning comes on...

I'm now running 54F and 59R. I would like to run a little lower but don't want to bump up too close against the warning light trigger. I would like to adjust the limits a little lower with forescan but don't want to set it up just for this. If there is anyone in the NW burbs of Chicagoland that is set up and knows how to make the TPMS adjustment, PM me and maybe we can see what we can work out to have it done. Thanks to everyone for your input.
