Close Call!
I've been having trouble with the Tire Pressure Monitoring System. It kept telling me my passenger front tire was flat, but repeated pressure monitoring showed 32psi. This started in April. I was going to have it checked, but life got in the way.
Fast forward to this past Saturday. My wife an d I put 215 miles on the car running the back roads of Louisiana. When we got home I decided to use my Cub tire monitor to check the inflation of all four tires. The passenger front still showed 32psi. When I checked my passenger rear ( which showed 32psi on the DIS) I got a reading of 5.2psi! I checked it again and then used an analog gauge and got the same reading!
So it looks like the TPMS is set up incorrectly and I put almost 400 miles on a deflated run flat tire (at speeds up to 85 mph)! There is a lesson here. Always check all of your tires even if the TPMS shows all are good!
Now I have to find a new tire since I don't trust the tire to last. It doesn't appear to have unusual wear, but I haven't pulled the wheel yet.
Ouch!

Hopefully your tire is still fine,maybe a litte extra wear. This has been a common occurrence for years. Some people get a little testy when asked if they checked all tires. Sounds like a good trip. On the bright side, you did not have to deal with a flat tire on the trip!

A few weeks back, I had a nail removed from rear right tire. The monitor indicated rear left tire was low. The front sensors were reversed as well. It came this way from the factory, as I hadn't touched the tires since purchasing. Dealer reprogrammed both.

This morning my daily driver told me I had a low tire. Unlike the Vette, it doesn't specify which tire is low or show the pressures, just that one of them is low. I almost prefer this for a car with the same tires because rotation would be a pain. The guy at the tire place checked them all, found a screw in the tire that was low and fixed it. I wouldn't have know there was a problem without TPMS so I am glad it is mandatory. It's like everything else, we just have to know its limitations.

I'm glad you found the problem without major incidents. I track my car, and a tire pressure gage is always nearby. Technology is great, but not perfect.
