Useless TPMS?

Well the other day I was on a 2 1/2 road trip to see the inlaws . On the highway had the cruise set at 100 km/h and noticed that the fuel mileage wasn't what it normally is when set at that speed. Out of curiosity I decided to check the tire pressure about half way through the trip at a gas station that had air, and behold, I had 23 psi in all four.

I was kinda upset cause I thought this damn car was supposed to have TPMS, I checked the manual and it stated that it does, even though it appeared to not be working. Of course I filled all of them to the recommended 35 psi and went on my way.

The next day at work I decided to check and see if and when they would ever come on, so i started the car and proceeded to deflate my drivers side front tire, turns out that the light will only kick in at about 20 psi???? What good is that!?!

But....... it will only go back out when the tire gets back to 35 psi.

Just wondering if anyone else has tested theirs to make sure they are working correctly.

The system is designed to detect a wild swing between tires, but if they are all at the same pressure it may not sound the alarm as there is no delta pressure to the other tires.

I would have to say that TPMS is more of a federally mandated cya device then an actually useful tool for owners. As you have just proven, it is no substitute for checking on your own at least monthly. TPMS is just a response to the Firestone/Explorer fiasco of a few years back.

OASN, I had a blowout at 70mph in my 2012 Subaru due to hitting road debris. TPMS never told me that the tire went down, of course I was only driving on it for less then a minute after the incident. It really is only useful to tell you of a slow leak that could affect handling if left uncorrected.

I know of lots of other car that freak out at you on a cold morning until the tires warm up from driving them. Almost over sensitive. Just seems kind of dumb to have them if they are only going to tell you when they are pretty much flat.

I know I'm bitching, just seems kind of useless to have paid for it (in the price of the car) and have it not really do anything for you.

Like suss6052 said, it should show when one is lower then the rest, or when they all are under a certain threshold.

We drove for years w/o TPMS, and it really wasn't created to help us, it was put in to keep lawyers employed.

There definitely is no substitute for the reliability of checking them yourself, but having for instance one front tire 14 pounds less than the other will cause some messed up handling. Yet no light to inform you. If they installed these things for our safety, the margin of error shouldn't be so large.

I think the system would be a much more useful tool if Ford reprogrammed the onboard monitor to show us the actual pressure for each tire. I mean, I know its very easy to do, its just a programming change for the 4" display in the dash...some Euro versions already have this. I was in a rental Dodge last year, and it showed the pressures for all four corners of the car, so, you knew exactly what each tire had... now, that is useful.

That is probably a feature in the more upscale models. TPMS is a federal mandate, how it is displayed is a matter of cost and packaging. This is a Focus, not an Audi.
