Default More TPMS Questions ?

Hi everyone!

The tire pressure display shows five readings, which one on your car is the spare tire?

On mine it is the middle one, the third, that makes sense the factory would set it like that so it never changes regardless of tire changes?

There does not seem to be a definite pattern to knowing which display relates to which tire, you have to take the time to figure it out yourself?

Ok last question, back to the accuracy of the TPMS versus hand held gauges. I have tried two digital and two sliding stick hand gauges and they consistently read about one a half to two pounds higher than what the display says the tire pressures are, this your experience too?

I note this difference also my 2012 Toyota Camry Hybrid, hand gauges read two pounds more pressure than the car's display.

They both can't be right, anyone tell me which is correct, and if you say the car is always right as some maintain then why is that? Thanks for your comments!

What year ? My 2007, it's a guessing game, I understand on the newer ones (2013+ ?) that they will show exactly what tire is low.

I tried a bunch of gages... the $2.99 digital one I have is about 1 to 2 PSI off, the others vary too much. I ended up sticking with the cheap-o one and it seems to do me.

My gauge also reads 1-2 pounds higher.
