Not sure what you mean when you say the Ford TPMS is not flexible. I have a 213 F 150 and the manual tells you how to change it. Also just had tires installed at the dealer and they said they could change it. only thing is it has to be less than the tire pressure you are running. In other words if you're running 65 PSI front and rear then the TPMS would have to be set below that. in my case the TPMS is set at 35 but I am running my tires at 55 of course the downside is the light will not come on until the PSI gets below 35. But it will work fine when I'm not telling and have the PSI set at 35 - 40. it can be changed but it's not easy to change. That's the reason I left mine set at 35 rather than changing it back and forth.
