Some people still question the need or value of using a TPMS. Some claim that checking tire temperature with an IR gun or touch with the back of their hand every two to three hours is sufficient. They seem to forget that it is possible to destroy a tire in as little as 10 minutes.
Others still think they know what an underinflated tire "looks" like but I have repeatedly demonstrated with hundreds of participants at my RV Tire Knowledge Seminars that no one is able to identify the difference between 35 and 14 psi in a P type tire or the difference between 46 and 66 in a LT tire. Some folks just don't feel the cost justifies the value of an advanced warning of an impending tire failure.
Well, I ran across the following post on an RV forum thread on tire failure on an RV.

FYI....Be maniacal about checking tire pressure and invest in a TPMS system if you have not already.
This past week, two incidents proved that a TPMS (tire pressure monitoring system) investment is worth every penny.
Coming back from a long trip on Memorial day, my caravan friends, who did not have a TPMS on their 5th wheel toy hauler, lost pressure in a rear tire which became overheated and eventually blew on the interstate. The damage the blown tire caused to their meticulously maintained RV added up to $3000 in body work. I hear this is typical...and often at the low end of cost for damage when a tire blows. My buddy has talked about investing in TPMS...but chose not to spend the $. The insurance deductible alone for the damage was $500. Lesson learned.
A few days later, I was back on the interstate headed for a camping trip to the lake with my 5th wheel toy hauler. I have invested in a TPMS....and am so glad I did. At 65mph....all of a sudden the display on my TPM system flashed red and displayed that my right rear tire on the trailer was "leaking". I was impressed that it alerted me when the tire pressure was down only by 2 pounds...and I could see on the display the rate at which it was deflating. This gave me sufficient time to exit the highway, park in a safe place...and not suffer any damage to my RV....let alone save the tire which picked up a screw.
This device is worth its weight in gold....and I highly recommend it to anyone pulling a trailer of any kind. You will never know you a have a problem until it is too late without it.
There you have it -- a direct comparison of the value of TPMS vs no TPMS.
