Would love to have a TPMS, but as many have said, the leaking aspect overshadows that. I may try to pick up an infrared thermometer. I trucked for a few years in a former life and blew a couple of recaps off the trailer. That was in the day when the 'cold caps' were all the rage. They were fine until one turned loose - then it was not pretty!
never had a leak....in fact the only problem i did have was a cracked valve stem (should have had 'em change 'em when they put new tires on).....the valve stem was fractured at the nut/wheel - over a year after i had new tires put on & had driven several 6 or 8000 miles that year.
I went over to my coach / storage bay to turn the fridge on for a trip & turned my TST TPMS monitor on and discovered my front steer tire was down to 80 lbs....took me a while but eventually (w/ some soap and water) i found the leak....aired the tire up and took it to the shop.
if someone is threading the cap/sensors on properly i see no chance for a leak - they even have security caps to keep the sensors from spinning loose - i ran 'em for a year & then removed the caps & have run w/out the security caps for 2 years now.
initially i was fearful of theft but to solve that i put a little dab of thread lock on the valve stem - but I've never had anyone mess w/ 'em. you could do the same thing (and continue to use the security caps) to prevent loosening too....but again its a non issue.
if thats not enough to calm fears then go w/ the INTERNAL sensors (5 or 10 yr battery life) from TST...theyll never LEAK or be stolen !
