I think an inaccurate reading is far more likely.
Heat will increase pressure, but if it made it all the way up to 72psi the tire likely would have suffered severe damage or wear.

If you checked the pressure, and it was normal in all four tires, I cannot imagine that something like a tire inflated with double pressure would have occurred. I would say a faulty TPM sensor would be a more likely culprit. Any time one of those stops working or is not present, the result is the exact sequence you described: The light blinks for a while shortly after starting the car (probably 30 to 60 seconds later), then remains steadily lit. I have a set of wheels on my '10 Forester with no TMP sensors in them, and this is the result. I am not sure if it behaves the same way when a sensor is reading a condition "out of range," meaning the pressure is either too low or too high.
However, in the event the tire was overinflated so severely, the result depends on several factors: 1. The tire's integrity (number of miles, condition of materials, etc), 2. The road surface, 3. the vehicle's load, and 4. the ambient and road surface temperatures. Basically.... heat + pressure = boom.
This time of year (cooler temps), of more concern may be the amount of vibration being transferred to the struts and wheel assemblies. Over extended periods, that could result in premature wear of parts.

I love it when we get all scientific!

I agree with you 100%! It is the dealer who insisted there was 72 psi in one tire. I certainly did put that much in. The problem occured between the time I left the car for service on that afternoon and 1/2 mile after I left is when the light went on.
Could a tire even hold that much psi without blowing? You are probably right the dealer read it wrong. But, you would think, from a dealer, they would be intelligent enough to know whether that is even possible.

Yes, a tire can hold that much pressure. I know from experience....
#255 of 298 Subaru Tire Rotation Question
Mar 16, 2010 (6:36 pm)
I have a Forester. Does it matter where I have my tires rotated? Is there anything I need to be aware of with the AWD?

Rotate 'em every 7500 miles or so to keep wear even on all 4 tires. You want to keep the circumference of all the tires right about the same.

I need 4 tires for my 04 Forester xs;could use some recommendations
p21560r16 AWD, 25k a year Boston area and need to be mobile in the snow
I got a real good price on 4 Falcon tires??

I have a 2006 Forester and last checked my air pressure in mid September. I usually do it every other week but I fractured my ankle in early October and have not been able to drive since and my wife has become my chauffer. Checked my air pressure yesterday and all 4 tires were at approx 15 lbs. My mazda, also with alloy wheels, is fine. I understand that sometimes air can leak around alloy wheels. OK. But is there any solution other than checking the pressure weekly?
