Hubs should not have anything to do with TPMS.
But temperatures can and will cause the tire pressure to fluctuate.
65 PSI is the BOTTOM LIMIT of your vehicles tire pressure, if your tire is set to 65 at say 70F then it IS possible that the pressure will drop to 62 PSI at 20F which WILL trigger the TPMS light.
My 2013 F250 triggers at 63 PSI and goes off around 70 PSI.
For winter you NEED to ensure ALL tires are at 67-69 PSI at the ambient temps you have at the time in order to not get an alarm at 20F or lower.
Running empty I keep my fronts at 69 PSI and the rears at 67 PSI and I don't get TPMS lights during winter.
