I have lost 25 lbs of air pressure in one tire in the past 6 weeks or so sitting in the driveway . Turned on the TPMS to check for the upcoming trip , and three were 102 psi. , the low tire was 77. ...
You didn’t say but I would air it up to at least 110 psi then put the weight down on it and then start soaping it down good.Take your time and watch very close.
