Hey all you guys who have a 350z, do you know the tire pressure gauge on your gauge as an option. how do you get it to check your tire pressure? I have a flat tire and it says nothing. what do you guys know of that?

 

Depending on the model year and trim of your Z, you may not even have TPMS.

The sensors only read when the car is moving, if you have a flat, you're not moving so you won't get a reading.
