Quality and TPMS

Any tire from any MFG can suffer a run low flex failure (i.e. Blowout) due to puncture, cut of leaking valve. Leaking air is what TPMS are designed and intended to warn about.

Poor or lower quality (design or manufacturing) would seldom result in a leaking tire. Weakness in the design/mfg of the belt package will more likely lead to a tread and/or belt separation and TPMS will almost never provide advance warning of this failure mode.

If you don't know or understand the real Root Cause and the mode of failure, how will you know that your "corrective action" is actually addressing the Root Cause.
You can think of it this way. If your car doesn't start, will replacing the battery solve the problem if the Root Cause is dirt in the fuel?

Had 2 tire failers on this trip from Vanc., Wash. to Mt. Airy, NC. They were G rated Carlisle's, one went bad at 10 mph, and the other at 65.....rr and lf on this trailer..not a bit overloaded, I put it on age of tires.......they were on it when I got it......I replaced all 4, and keep 1 take off to see date code....will do that tomorrow..so, as it turned out, now have 2 g rated Hercules and 2 d rated Goodyear St's....all that was available at the time....so I'll be doing a tire test on the way back home

I don't doubt that you discovered the tire failure when you were traveling 10 mph but clearly something happened earlier in the tire life. What was the inflation at the time of the "failure".
Since you apparently need LR-G tires and I assume you were running the specified 105? How are you compensating for the significant reduction in load capacity when you went to LR D Goodyears?

I have been running with TPMS system since 2009, but all my failures were of the catastrophic type. explosion and then seconds later the warning. I have fixed ones set for 75 psi on metal stems. If I had picked up a nail or something else causing a slow leak it would alarm. But I agree with your statement

Sorry but "Catistrophic" is not sufficiently descriptive to allow me to offer an analytical opinion. You might want to look at the pictures and the results of the autopsy for this "catistrophic" failure. Now this one was a Run Low Flex failure but the owner was not running a TPMS so had no warning which is why he originally thought it was a "defective" tire as he had checked the air 50 miles prior.

RE Belt/Tread Separations. No TPMS will provide warning for this condition. Close visual inspection and the identified "free spin" inspection, would probably discover a vast majority of these failures before the tire disintegrates. Thats why I suggest an annual inspection for TT tires. An impending belt separation on a TV or MH can many times be felt by the driver of a TV or Motorhome if attention paid, with no distractions on smooth road.

I have never had a flat, I have never had any problems with my tires other than wearing out. I pull a Cedar Creek 32RL fifth wheel. I have been to Yellowstone from NC. I normally drive 63mph when I'm pulling the camper but when I have to more. Empty I run 70 to 80 on the Interstate, around town whatever I can get away with. The bottom line is I have no problems using rubber valve stems.

you don't have problems with rubber valve stems YET . i quit using them yrs ago when they all starting coming from China . had to many flats on my autos from bad valve stems . just a couple weeks ago caravaning with another RV'er got a call from him on the road (he was behind me ) saying that a passing car signaled him his TT tire was low .lucky we were right at an exit . pulled off checked the tire and low and behold the valve stem was cracked and leaking . filled tire and limped to a walmart a mile away where they installed another cheap rubber valve stem but it got him going .
when I put the new e rated tires on my TH only 10 days after purchase metal valve stems were a mandatory thing same with my TV . the cost is cheap compared to sitting on the side of the road with a tire that now is now good because a cheap valve stem . just saying you'll save yourself a lot of headache by just installing metal stems .

you know what Murphy says .

I am just saying I have at least 30,000 miles on my truck tires. I don't keep the locks on the sensors so that helps a little

you have aftermarket sensors on your truck ? i had a car once with the tps what a pain . i always check my tires don't need a sensor to remind me . the bad part was when i put the snow tire and rims on no sensor and the dash light became an annoyance . Seems the sensors make since for a TT , TH , 5'er but also seems by the time it tells you you have a flat it's to late

Soooo, what went wrong? Pressure at max, temps under 100* and please don't tell me I hit pot holes with all four! TowMax. All under three years old and yes I did send the pix to NHTSA. Never heard a word from them. Nada. Coincidence or garbage tires? There is one more, but I didn't take a pix of it as I put it in the trash at the CG.
