are the TPMS sensors in the 350 just monitors or do they trigger an alarm or light similar to smaller cars or trucks?
what is the standard tire pressure for the F-350?
what is the variance threshold before an alarm or light is triggered if they are more than just a sensor?

on my gmc there is about a 12lb psi allowance before a light is triggered

 

It's a warning message when you start the truck and a constant dash light. You have to acknowledge the warning message everytime you start the truck by pressing "ok". Before adjusting the threshold with FOREscan I was able to have the fronts at 55 without tripping the sensor. Had the rears down to 65 and it still tripped the sensor. I heard someone say you can go 10% below what the door jam says before tripping the sensor.

 

So if you are setting the pressures in FOREscan is that the trip threshold or the actual tire pressure.

 

The trip pressures. My sensors still show the actual pressure in each tire. Just no warnings until I get below 10% of 50 PSI

 

was that on a 350 or 250?

thanks

looks like i will be getting the set-up for FORscan and learning how to use it

 

I know nothing about it either but thanks to the forum I was able to meet up with a member who did and he helped me out.
