TPMS question
 

I have a 2013 F350 CC 4x4 with 275/70/18 tires. I would like to reduce some tire pressure but I don't know how low I can go without alerting the TPMS. Anybody know? Thanks.

on my F250 the rear calls for 70 psi and I can run 60psi with no light.

Suggest trial and error.

my door sticker says 65 psi. In the morning there down to 57 psi and no light! 2013 F250 with 18s from the factory.

that TPMS is easily programmable if the tech knows his stuff.

However they did charge 1/2 hour to reprogrm mine to 55psi

I dropped mine to 60 psi in the front and 65 psi in the rear. We will see what happens.

I don't know where you guys are finding techs willing to put the dealer on the hook for reprogramming tpms. The fines are atmospheric and the potential liability is huge. Not a one here will touch it.

Might find some ideas here....

I just drove 20 miles and no light, yet. Keeping my fingers crossed.

Well...it happened. The dealer refused to reset. Either live with the light or the higher pressure.
