A few years ago I had a sudden blow out due to a faulty tire on the trailer....not fun and expensive. This got me looking into TPMS systems. Will it warn me about a faulty tire that is about to blow out? Maybe.
Here is what it did warn me about so far:
1st. Had a rear caliper seize on my diesel. Temperature alarm on inner dually tire went off and there it was at 190. 30 minutes and one caliper later. Problem solved.
2nd. Recent trip noticed 3 trailer tires were at 90 degrees and one had climbed to 160 degrees. No alarm but a good indication to pull in the rest area that was coming up in 2 miles. A trip to Statesville NC Camping world and brake assembly later....back on the road. Big thanks from me and my family to Camping World for keeping the lights on for me to get the parts!!!! And thanks to NC troopers for not towing my un hitched trailer from the rest stop.
The Dill system is expensive and I questioned if it was worth it. Now I think it should be law to have new trailers (including equipment trailers) to have TPMS). A professional driver that stopped next to me and kindly offered me some GoJo to clean my hands after the brake job said that it is very common on the 18 wheelers now. I also place a value of being able to not have to check tire pressure in the rain ($20, 5 a tire).

I bought mine from Tim at Eastmen Tire Supplies in Bulter PA. Very helpful when I expanded the system from the standard 4 to include the 6 extra tires of the dually. All around good guy, consider giving him your business.
