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. ...
Spend $15 and have the rim cleaned, the tire remounted and sealed at a local tire shop. I would never head out with a tire that is leaking. Just an accident waiting to happen.
