Tire Blow Out & TPMS

I have come to the conclusion, it is not if a tire will blow, it is when...

My question is, has anyone had a tire blow, catastrophic failure, and your Tire Pressure Monitoring System alert you? I blew a tire and the TPMS did not tell me, a passing motorist did. I was driving on the rim. I have some damage to the 5th wheel. I am working with the TPMS company now, so far no reason for the monitoring system failure but the suggested solution is an upgrade. I am debating what to do...

Thank you

I've had two alerts, (overheating) no blow outs.

If the TPMS monitor loses connection with the sensor the period of time it takes to notify you of the loss of signal can vary a tremendous amount. Some brands can take up to an hour to notify you of a lost signal. So you could be traveling for an hour with no contact with the tire/s and you wouldn't know it. And the sensor could reconnect and you'd be none the wiser.

Some brands are very quick to notify you of a lost sensor signal. It just depends on the brand. My guess is that the maker will recommend a repeater.

I have an older Pressure Pro. Have had 2 blow outs on dolly tires, and both times the TPMS notified immediately.

Was the TPMS sensor still on the wheel? If it was you should have got a low pressure alarm.

If the sensor was blown off the wheel it may have been out of range before it was able to send the low pressure alarm. ( this can take a couple seconds for most systems)

We had a TPMS when our tire separated so quickly and failed, that the TPMS did not alert us.

We twice heard the boom then were alerted :(

The statement that "it's not if but when a tire will blow" is true if you're running Chinese made trailer tires. As we've discussed repeatedly, Chinese tires have extremely poor quality.

On my last 5th wheel and on my current toy hauler I run Michelin LT truck tires and not once have I worried about a tire issue. I also don't have to baby the tires the way we do ST tires.

Have you noticed that it's the trailer tires blowing and not the tow vehicle's tires?

You didn't say what brand of TPMS you have, but whatever it is... I'd get rid of it and get something that works.

That was also our experience - but only 1 X

80K miles with TST TPMS, several alerts with 2 catastrophic failures. No notification of failure and significant damage. (Tread separated with no loss of pressure) The other failure was a tread separation and blowout with instant notification.
