That is why I typically take a marker to the tire on the car I want replaced, and I write "SCRAP" on the outside. Sharpie markers don't always show up, so if it is not raining, use Chalk. Otherwise, I use one of those junkyard pens that are really permanent.
This tread has veered way of track from Eric Z's slow tire leaks to cutting off the wrong leg! I understand Eric O has worked on a lady's fake leg once and Eric the Car Guy is likely to pull your leg. Here we get Fuzzy logic and Sammy Rickles insulting everybody for the fun of it. Meanwhile two slow leaks have become mysteries of the universe. Maybe we need Jason from Engineering Explained to fill four white boards to define the physics of the problem. While we wait for the exciting conclusion, Happy Holidays!
I hope the tire pressure issue have been resolved by now .. If it hasn't and want to DIY, then the best way and I have recently helped a friend with is to take rim off car then lay it down to the ground and spry soapy water to rim/tire and tire valve/tpms sensor for air leak.. I found 2 Valve/tpms sensor leak, and replaced valve core seal/nut after cleaned out corrosion build up to rim... Problem solved after... Good luck Posted via the PriusChat mobile app.
This same thing happened to my Goldwing....... took the tire off and cleaned the rim with 0000 steel wool.....
Thanks for the advice. It did turn out to be two slow leaks. I never did find them myself, but I ended up taking it to Goodyear, and they were able to fix the leaks, and the two tires have been holding their pressure for weeks now.
Many thanks for the update. Too often, we don't hear the final resolution, so don't get guidance for future similar questions.
