2012 F-250 Gasser tire PSI

If this has been discussed please forgive me. I did a search it didn't find much specific to my TV.

I have a 2012 F-250 CC SB 4x4 with a new set of Toyo Open Country AT's. I have recently replaced the shocks with Bilsteins and they definitely helped. But it's still a very rough ride. I'm well aware of the fact that number one it's a gas truck and its lighter and will ride differently than the 05 diesel I came from. And number two its a 3/4 ton SD truck and not going to ride like a car.

But....it's rough! I have played around with tire pressure's some and its helped. But in order to get a half way decent ride, I have to drop them into the mid 50 psi (not loaded or towing) range which sets of the TPMS. The tires are LRE with a 80psi max rating. Right now I'm at 65psi on all 4 corners to shut up the TPMS and for towing the 5th which weighs in at around 9500# loaded and ready.

So my question's are... What are you guys with similar rigs running? Can I reprogram the TPMS to accept a lower psi when empty (don't see anything about this in the manual)? And could it just be I selected a hard tire (after extensive research, and toyos being highly regarded)?

I of course will readjust pressures when planning to tow/and haul as this isn't a problem having a compressor in the shop. I know I want my cake and eat it too, but when the DW ain't happy with the ride....well you know the rest!

Thanks,
Scott

  • A good place to start is to reference the appropriate tire inflation chart to ensure your tire pressure is safe for the load.

    Sample Michelin Inflation Chart

    I have not run through the procedure myself on my F-150, but here is the procedure I found referenced. I believe you will find this in the manual, but the manual neglects to mention you need a tool to identify each tire. Here is a link with the procedure.

    2012 F-250 TPMS Training

    And lastly, here is the tool required to help train the tires.

    ATEQ Tire Training Tool

    As stated above I have not done this procedure myself on my truck, I had just done similar research. Please do your own homework to satisfy yourself that this will work for you. You may want to check with a local tire shop and they may help you out.

    They make inflation charts for a reason. Seems to me you inflate to the load you are carrying. A buddy of mine was a fleet manager for 30 years and did the same thing on their rigs.

    Good luck to you,

  • Here's a thread on 350 rough ride.

    Advanced search, keyword= ride, subject only, tow vehicles.

    About the only way I know to help the ride is to install Link air ride or eq. Get rid of the leafs.
  • 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
  • I have never heard that the Ford TPMS can be adjusted.

    I run 65 in mine and yes it rides like a tank. My Bilsteins helped marginally unloaded and quite a bit loaded. After 5 years and 80K miles you could say we are used to it.
  • Not from actual experience, but yes, that is my understanding after talking with my dealer.

    Well Scott, I think if you can get by running 65 all around, and satisfy the TPMS, that is about as good as it gets.

    AFAIK, the TPMS can be adjusted, but you would have to do so, every time you towed, and again non towing.

    Jerry,
    Thanks for the reply. One question though. If I reprogram to accept a lower psi, lets say 55, it will activate when I raise the psi say 10-15psi to 65-70 for towing?
