WASHINGTON, D.C. General Motors is recalling 4,586 2008 Cadillac STS and STS-V sedans for a problem with the tire-pressure monitoring system. The National Highway Traffic Safety Administration says "indications of a system malfunction do not work," which may result in "premature tire failure [that] could result in a loss of control of the vehicle." "When the system detects a malfunction, the low-tire warning light should flash for about one minute and then stay on the remainder of the ignition cycle," says NHTSA in its recall summary of the problem. "A driver information center message will also be displayed on the instrument panel." NHTSA says Cadillac dealers will reprogram the remote control door-lock receiver module for free. Owners may contact Cadillac at (800) 982-2339. (Edmunds.com)
I don't think this has anything to do with run-flat. TPM just sends a signal to your dashboard so it can warn you that one or more of your tires are losing pressure.
They probably have the sensors because of run-flats though. Cars with run-flats are required to have them. There isn't much point in having the sensors with regular tires unless you're a blind moran.
Run-flats or not, people should check the tires pressure twice a month, in which I do. Americans are so lazy.<A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/tongue.gif"></A>
I check them and my oil each time I gas up. <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/tongue.gif"></A> There's nothing else to do while I wait those few minutes for my tank to fill.
It takes far less than two weeks for a tire to go flat. <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/tongue.gif"></A>
If the tire leaks enough to make the sensor go off, you should be able to notice it if you pay attention to your car.
