It is a truck...
what size tires? You know the recommended rim width range for 'that' tire?
What type of tire? Brand, model, tread
What wheels? OEM? After market and if so, what is the rim width
What model Bilstein?
Suspension lifted or any other suspension mods?
Tires are part of the spring package holding up weight. Tires have many other
duties too
I don't recommend ever airing down an LT load range E down below 65PSI...unless
going off roading and NOT going to go above 35 MPH
The TPS is mandated due to Ford, Firestone and the people (owners) who don't
understand tire pressure at the other end of the bell curve...the extreme end
that is the day Mr Murphy crosses you path.
For "Ride Quality" purposes, Ford changed their glove box tire pressure
recommendation by lowering it. One too many deaths from accidents caused by too
low tire pressure had the government stip in all the while Ford was pointing
fingers at Firestone and Firestone point fingers at Ford.
What pressures do you tow at? That is why the comment of having to reprogram
from the too low PSI to the proper towing PSI
"Ride Quality" is best with a narrower rim on 'that' tires recommended rim width range
"Performance" is best with the wider rim on 'that' tires recommended rim
width range...but then I wasn't happy. As if drove like a car and
reduced response. Could no longer 'thread the needle'...
I run my LT265/75R16E's at 80PSI when towing. Front and Rear. When
used as a 'car' run the same and know it is a truck. I also drive
very, very hard...because I enjoy driving hard.
The 'ex' didn't like it and did drop it down to 65PSI front and 70PSI rear
