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.
Thanks for the info. I would have done the same thing as you. I would have never thought about that. I think its time for me to dig out my tire guage and check them all.
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.
I wouldn't replace the tire, just keep an eye on it after bringing it up to normal pressure. I don't ever depend on TPMS readings, I check my tires regularly with my analog hand held gage.
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 filled it to 32psi and within 1.5 hours it was down to 26psi. Most shops I contacted don't want to touch it.

So, new tires on rear today!
Ended up buying Bridgestone Potenza RE050A Pole Positions. Used my Cub tire tool to do the re-learn procedure. Now all TPMS Sensors show up in the right positions in the DIS. The affected tire had some unusual wear to it.

A Cub Tire Tool is a tool used to service your TPMS Sensors inside your wheels. It can relearn, take preasure readings, and interact with the sensor. Best $20 Bucks ever spent.
You can order one from Tire Rack as a close out for $20 Bucks.

Bob, not trying to be a smart arss...but it is DIC not DIS, Driver's Information Center.
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.
