JoeR Posted June 17, 2019 Share Posted June 17, 2019 GM and Ram Pickups are capable of adjusting the desired tire pressures up or down depending on what the customer needs. For instance if you have a 3/4 ton truck but never carry anything in the bed. Having 80PSI in the back tires is not desirable. You can change that to 50 PSI, change the placard on the door, and run 50 PSI instead of 80 PSI with no TPMS light. I've never seen that ability on Ford vehicles. Am i just missing it in the IDS or is it not a function on Fords? Thanks! Joe Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted June 17, 2019 Share Posted June 17, 2019 We used to be able to change the tire pressure specs in the BCM. I think that disappeared years ago along with changing tire size by RPM. Quote Link to comment Share on other sites More sharing options...
cbriggs Posted June 18, 2019 Share Posted June 18, 2019 We have an Autel tpms tool that will adjust placard pressure on all current ford vehicles. I have some bright red labels made to put next to the load placard in the door jamb to indicate it has been lowered. Quote Link to comment Share on other sites More sharing options...
