Overpressure In Tires

Last week my wife and my her friend went to a cat show about three hours away, and on the way they stopped and had the tires checked. They went to the show and came back.

This morning I get in her car (a Town & Country Minivan) and the trip computer is telling me that 2 tires are over-pressure. So I get a pressure guage and check.

Her front tires both had about 65 psi of pressure!!! And that is cold, 55 degrees F without the car moving in the past 12 hours.

When she drive to and from Ohio last week, on the highway at fairly high speed (my wife tends to drive fast), I'll bet the pressure hit 70-75 psi.

I am stunned that the tires held up! I feel like writing a letter to Michelin to tell them about their tires and thank them.

Does anyone know what the typical burst point of a passenger car tire is? If not burst point, perhaps when the rim seal is compromised. A front tire blowout in a front-heavy minivan at 80+ mph cannot be fun.

I told my wife she's used up 8 of her 9 lives on that trip.

I have personally seen passenger car tires inflated to roughly three times the maximum specified pressure. Pretty scary when you think about it, considering all it would take is one well placed pothole to ruin your day. As for your question, unless the rim was equipped with a high-pressure valve stem, more than likely the valve stem would be forced out before the tire burst.
