However, a few other things were mentioned that caught my eye:
-> "Reset" option in the menu
-> Green button in the glove box
-> pp 229-231 in the manual

I could not find the green button on my 2010 F250 glove box, and the manual talks about tire pressure but nothing about resetting TPMS. It is mentioned in the computer system check though. I wonder if there is some secret button push pattern you can do to reset the pressure?

For my situation, I would sure love to set the TPMS much lower. All I care about is if I have a leak and the tire is getting soft, so 30 lbs would do it for me. Still hoping to hear something good. I expect it will be something you can do through the OBD port or some hidden USB to lower the computer's threshold.

Instead of the fault coming on at anything less than 75, I had him lower it to 65. 65psi is the max for my after market tires. Light is off and does not turn on unless one of my tires is lower than 65psi.

Why would you want to disable it? If you get into an accident from a blown out tire (overheating from underinflation) and they find it has been tampered with, You would be looking at major court time even if no one gets killed.
Lowering the psi can be dangerous and expensive. Not only do you risk overheating the tires and having a failure, but at the bare min. you will decrease the life of the tire. Under inflated tires will wear faster at the edges, and the sidewall will flex more cousing it to crack and dry out reducing it's strength. I have had many cust. replace tires at half life because they were cracking and had excesive edge wear from underinflating. The center tread would still be good, but the tires can not hold air very long from the cracking sidewalls.
Lowering the pressure just isn't worth it, sure you may get a smoother ride, but you bought a FORD SUPER DUTY PICK UP not a f***ing Mercedes. The truck is made for work.

the majority of the systems available are REPROGRAMABLE. When you "RESET" the light on 90% of vehicles, it gets reprogramed to what ever pressure you currently have them at. I had a customer just today came in for an Oil change on a Toyota, the tiretech doing the oil change called me over because he noticed that one tire was at 15psi but the tpms light was not on. after talking to the cust. we found out that they learned how to reset the light and instead of checking her tires she just kept reseting the light. Turns out she had a small bolt in the tire and the system was warning her about it, but she decided to cover it up, if we did not check her pressures she very likely would have had a blow out sice she does alot of highway travel.

Tpms was made a requirement for a reason, not just for you saftey (like seat belts) but for the saftey of other peaple on the road. If you have a blow out in one of these trucks, that can lead to loss of control and possible rollover, putting others at risk.
