I was told by a friend they're IS250 shows the actual tire pressure number on the small display in the dash. For the life of me I researched and couldn't find what they were talking about. I've had my car for some time and i know for the 2014 models, the 3IS, it shows the actual number. Am I wrong here to say that a 2007 Lexus IS250 (unsure if it's RWD or AWD, they didn't know) DOES NOT have the ability to give you an ACTUAL number for your PSI?

There is no actual tire pressure reading. It will only warn you if your tires are dangerously low.

Correct, there is no way to view the actual output of the TPMS sensors without connecting a diagnostic tool to the DLC2 port and reading them that way. You cannot view pressures or temperatures in the tires on the dash on any 2IS models.
