Let's hear it for Tire Minder!

I purchase a new to me trailer, and on my first trip had a blow out, changed the tire and repaired the plastic that got pulled away from the trailer, I then purchased tst tire monitors, I checked the monitor and it showed that the tire that had the blow out that now had a brand new tire in the rim was low again. filled it up to just be safe and a few day later I had a low tire reading on the monitor. removed tire and wheel and put it in a tank of water to find that the tire had a leak from the center of the rim. I then removed the tire and found a small pin hole in a weld from the manufacturer. I silver soldered the weld area and remounted the tire and have not had a problem since, with out the tire monitor system I probably would have has another blow out. They now have nearly paid for them self in one occasions.
