I agree in Darwinism to a point - the problem is that those stupid people share the road with my friends and family and pose a significant risk to the rest of us. Except for that detail, I'd suggest we just let people kill themselves as they see fit. I've seen no less than a half dozen cars - just walking through my work parking lot this month - with severely underinflated tires.

My personal favorite are those who have been clearly driving around on space saver spares for quite awhile. That can't be safe. I am suprised I have yet to see a car with four space savers on at the same time.

I have seen at least one with 2 SS tires on it driving around. It didin't look like the driver could read English to understand the warning on the wheels.
Or it may be the latest fad in ethnic customizing? I don't drive our truck very much outside the AX season and since it has gotten cold out the tire pressure has dropped enough to trip the check pressure warning. I keep forgetting to add air since they don't look low, but the warning has not "timed out" so far. Maybe this will remind me to add air this afternoon?

That's only because you don't get 4 with the car. If you did, you'd see it for sure.

Often this can happen because the *spare* is low, too. Which is highly annoying. But obviously pretty important on its own. But might be why none "look" low...

Worse than this was back when we had Range Rovers. Several generations of those have air suspensions with auto leveling and such and it's computer controlled. It wasn't uncommon on those days where you had like a 40 degree temp change since you last ran it to crank it only to get a Check Engine light. Wouldn't cut off. But if you had your own tool you could check, find that it was an air suspension "alarm" and you could reset it and it didn't come back. It just saw too big of a pressure change for "no reason" and did an alert. I guess it was easier to program in a big range and hope for the best than to add a temp sensor and actually do the math to see if the pressure changed due to that or something else...

No, not the spare, mine actually tells you which tire is reading low. Hmmm, makes me wonder is there 4 receivers deciding which one it is or are the transmitters coded individually... Could make rotating the tires "interesting". I'm going to have to ask next time I'm at the dealer.

Well hell, that's a new one on me. Never seen a system that tells you what position was low. Maybe I need to get newer vehicles!

My MIL's 2007 Chrysler 300 does that.

I've had my tires rotated several times (by the dealer). front to back and diagonally, per the book. Maybe they retrained the car to accept the new positions, but I doubt it.

I wanted to note that I reviewed the owners manual and followed up w/ the dealer about the TPMS system on the mustangs. These are minimal systems and are simply pressure switches. When one detects a low tire pressue, it sets off the dash light and that's it. There is no integration into any engine management, does not use the ABS as part of the system and they are not directional.

That said, I think you could very easily just use a PVC pressure container, dump the sensors in it and be done with it. There should be no issues w/ the sensors having to be in motion.

And what happens if you just pull the fuse for the system?

Hmmm... and if you made the pressure tank large enough you could use it as an air tank at the races! :lol:

well, that depends. If it's like the ABS on the bimmer, if you pull the fuse, you create an open circuit and the light comes on. I suspect it would be the same for this as well that the light would just stay on.

The one issue that has me concerned now from motion stand point is (and reading the manual again), it states the light will go off after 2 min of driving above 20 miles an hour. How do it know that? Need to validate that piece. Time to go deflat a tire....

RodneyWright · **Posted:** Thu Feb 12, 2009 7:35 pm

ok, I deflated a tire to 15psi and finally got the dash light to trigger on. I filled the tire up and immediately sat in the car and fired it up. The dash light stayed on, so I drove down the street and then the light went off.

Not satisfied, I deflated the tire again and triggered the dash light again. This time after pumping the tire back up, I just let it sit for about 10 minutes while I peeled potatoes. Went back to the car, started it up and no light. Therefore I think the statement on the owner's manual is a ploy. You do not have to drive the car for 2 minutes over 20mph to make the light go off. Probably just need time to repressurize the monitor.

that's all I have on this....
