I am curious, at what pressure will the TPMS fire up a warning signal that you have a "flat" ?

Mine triggered today at 27 psi, but I found no nails or any other puncture in any tires. I will be bringing my MO to the local GoodYear dealer for them to check the tires out tomorrow.

Just want to get a feel for what you guys have experienced.

Doesn't signal a "flat". Signal is for underinflated tire. 27psi sounds about right.

My aftermarket TPMS is designed to signal when pressure falls 5 psi below the set pressure. I am assuming the OEM is the same way. So if tires have to be at 33, then 27 or 28 is when the alarm will sound.

Mine signalled at 27 and it said it was flat. I reinflated to 34 and the message went away. Must have been that winter air I had installed in March!

Yup, 27. I remember it being so cold this past winter that it thought all my tires were flat when I got going in the morning
