It's my understanding the radios in the tires have individual 'signatures', so I'm not sure why the indicator is limited to notifying us only that "something is low-- Happy checking!"

Since they are just radio signals of some sort, is there perhaps a 3rd party device that could be used to receive and provide more information? Or could such a monitor be built from parts available at Radio Shack or an electronics outlet?

Before anyone reminds me all tires should be checked, routinely AND when a warning light comes, I do. My issue is that the TPMS light (flat tire icon) comes on; I check the tires. Usually they are all within one psi of each other, and not low; I add a little air to each tire just in case; and repeat that process a couple of times a day until after a couple of days the monitor system is happy again.

Of course the light usually comes on when: I'm late; or about to begin a long drive; or it's raining, etc. As in, very inconvenient-- so having to iteratively search for the half-PSI "issue"; drive a bit and check again; repeat . . . very annoying.

So I'd like to be able to 'read' what PSI the tires are reporting. Wham, bam, low-tire issue diagnosed without playing "musical tire inflation."

FWIW, I have a good "dial" gage-- I can't imagine playing this game with a crappy little pencil gage.

Thanks for any help. JT
