False Tire PSI Reading
All I can find on searches is TPMS questions and this isn't really one of those.... I don't think. We've had a cold snap and yesterday the light on my 2014 Ram started telling me I had a low tire. ...

I wonder if its just a issue with the cold temps allowing for false readings on the TPMS senders? I had many "false alarms" on my minivan with TPMS at extreme temps especially if parked up against a curb. Could there be some moisture in the valve stems causing errant readings on your gauge? Perhaps get it into a heated shop for a few hours and try your readings again. My 1 ton usually sits at 60-70psi for towing but was horrible on snow. I finally got smart and aired down to 45psi for winter driving as my contact patch at "towing specs" was tiny and dangerous! Hopefully this is just a weather issue and not batteries dying in the senders.
