TPMS showing different readings than manual gauge?

My TPMS on my 07 type-s is showing ~3lbs less tire pressure for each tire than what my Craftsman gauge shows. I have 255/40-17s. Any reason to be concerned? I'm trying to get my PSI on all of my tires as pinpoint to 35/33 as I can for front and rear.

The TPMS isn't an accurate reading, they are there to provide you with a general idea of how much PSI so you don't get a slow leaking flat, when the PSI gets below a certain point it will warn you on the dash. For pinpoint results, use your manual gauge.
