You may recall my recent post about a tire problem on the new Mae. I recounted the experience in detail as to how I changed the tire myself (unheard of) and purchased a new tire from Discount Tire in Elkhart. (I found out later that the tire they installed was not the one I ordered, so I have a bit of a beef with them when we run across another of their stores.)
After getting back on the road leaving Elkhart, I was surprised to notice that the new tire also was leaking, but very slowly this time. We were in the middle of nowhere, so I kept going, keeping my eye on the tire pressure and airing it up as needed. In Butte, Montana, I had the new tire removed and checked, and the tire shop there couldn't find anything wrong with it. Assuming that I had yet another defective tire, I had another new tire installed in its place, thinking that getting two defective tires in a row was just an unbelievable coincidence. I returned to the RV park and hooked up to Phannie, and we drove off. Soon after I pulled away, the pressure alarm went off again on the second new tire. Imagine my surprise and angst after having unhooked and hooked Mae about four times in dealing with this tire!
When the alarm went off this time, it was definitely an "Aha!" moment. In a sudden fit of lucidity, I realized that the problem had not been with the tires! Wouldn't it have been handy if I had thought of this earlier? I decided to do some troubleshooting and removed the screw-on pressure sensor from the leaking tire's valve stem. Then I waited the better part of an hour and rechecked the tire pressure; it was right where it was when I removed the pressure sensor! The problem never had been the tires; it was the pressure sensor that was leaking! It never crossed my mind until now that such a thing could happen. Luckily, I happened to have a spare pressure sensor, so I installed it and have had no more problems.
This leads me to ponder a couple of things: 1) Should I have admitted publicly to being so dense, and 2) Since the pressure sensor remained on the tires when they were changed, why didn't the tire shop techs think of the pressure sensor as a potential problem, since they know a lot more about tires than I do? I guess I'll never know.
Does anyone need a couple of almost new tires?
Thank you, Lord, for this wonderful life; please forgive me if I don't appreciate it enough each day.
