TPMS Pressure

[secstang03]

Installed 35x12.5 on the stock 20's and can not get the TPMS light to shut off.

What pressure ranges are you all running with no light>?

[smotrs]

Look on the door sticker to see what the TPMS is set for, being and F250 it's 65PSI. So if your not reasonably close to 65PSI or within 10-15% approximately, then the light will stay on.

If your Ford Dealer Tech is smart enough, (and willing) have them readjust values in IDS to the load range D tire that you are running. I was able to get mine to do it on the threat of buying our trucks elsewhere.

or buy the tpms mod with your h&s tuner and turn it off or set the psi where you want it.

Can't be done anymore. Ford updated the software that allows them to access the IDS, removing the ability to alter the lower threshold. So of they have updated their systems, then they won't beable to.

That's probably your best bet.

Tires are 'E' rated and I run Spartan. I do not think Spartan can adjust accordingly.

[smotrs]

Nope, Spartan doesn't have that ability. Are those 65 or 80PSI 'E' rated tires? I'm guessing the former as your probably wanting to air them down so they aren't so harsh.

[secstang03]

They are 65 and the door tag says 65. I do not have a gauge on me right now so I do not know what Discount put in them as I was not there when they did it.

It is not the ride that bothers me, its the light. The ride with the Icon kit actually seems better than stock. I assumed Discount put too much or too little and was curious what others were running.

[smotrs]

Mine are filled to about 50PSI but then they are also only rated for 50PSI.

It's possible they under filled or over filled them. If you find that they are at 65PSI at all 4 corners and the Light/Msg Center still reports a TPMS fault, then it's possible your system isn't recognizing the sensors, the sensors are damaged, or the sensors weren't added when they put the tires on.
