OBTW there have been a few threads abou the accuracy of the system.
My system (and a lot of others ) is ALWAYS a couple pounds higher than the good digital gage I use to set tire pressure. Not a problem if you know the difference is there, you just allow for it.

I use a Joes Racing analog gauge with a bleeder valve when setting mine. Over inflate a PSI or two and bleed it down to the exact pressure. TPMS agrees exactly.

I have my 2019 Vette's tire pressure at 30lbs. I really don't have to worry about high temperatures in Juneau. It hit 82 last month but that was the highest it has been all Summer The garage I keep the car in has a steady temperature of about 55 even in the Winter unless some one leaves the door open
