Changing TPMS Pressure
I have 35x12.5-20 Toyos on my F350 which have a max pressure of 65psi. I like running them at 60psi.
I initially had a lot of problems getting the TPMS sensors trained to the truck after installing the wheels/tires but now that I have that sorted out I have the "Low Tire Pressure" telltale on the Message Center.
The tech at the dealer told me that the SJB learns the pressure from what they're set at during the training but obviously that isn't the case.
I've read in a few places that the SJB can be re-programmed for whatever pressure you want it to be, but it has to be with the Ford IDS diagnostic equipment. However, noone posted the procedure for doing this with the IDS and the tech doesn't know either.
Does anyone know what has to be done to make the truck want 60psi in all 4 tires instead of 65psi in the fronts and 80 rear like the door sticker says?
