2021 FLTRXS 114
I trust the TPMS to tell me when it's low, but not exactly what the pressure is. I have 2 pistol style gauges, 4 pencil gauges, and 3 digital gauges. They all read different. My theory is, I don't have a gauge that is calibrated, so as long as I can get it close enough to keep the low air warning off, I am good with it. When I didn't have TPMS, I only checked the pressure before long trips. On my 883, I have to check it every time I ride it (Just so it doesn't sit until I can sell it) because the front tire seems to lose a few PSI for some reason when it is parked in the garage.
