Tire Pressure Sensors
If the sensors do not measure exact pressure but have a 2 to 3 psi variance, then what use are they? I use a battery run valve stem pressure sensor. It is quite accurate. Many seem to worry about fixing a flat and ruining the sensors. If they are inaccurate then why worry if they are destroyed? Moving to GS/D3's from the runflats and will use the "fix-it" system in place of the sensors. Make any sense? :auto:

Re: Tire Pressure Sensors (Stan47)
Just a hand held electronic digital device that measures air pressure as opposed to the analog type where in the pressure pushes the numeric tube up through a shaft. More accurate :auto:

Re: Tire Pressure Sensors (Irish Whiskey)
I have a Z06 and pondered this myself. Actually I wondered why anyone would ever add the sensors to Z06's, when it's just as easy to manually read the tire pressures. Here is what convinced me to add this mod to my Z06; you can get a reading while driving and thus preventing possible wheel damage. And since I don't have run flats and spent a lot of money on my chrome wheels, I like the idea of having enough warning to pull over before any damage happens.

They made enough sense to me that I put them in my "summer set" of Z06 wheels/tires as well.

I use non runflats and would like to know ASAP if the tire is going down. It could give you a whole lot more options on how to deal with the flat.
I'm not sure about the accuracy range but all 4 of mine very closely match my hand held guage.

Re: Tire Pressure Sensors (Irish Whiskey)
According to my hand-held gauge, all my tires read exactly 30psi, but the sensors read anywhere from 25-33psi (different on each wheel). I was worried, but then realized that they will do their intended job and tell me if one goes flat.
I'm still on the run-craps, I just can't see replacing 4 tires with 85%+ tread on them... I'll be going to GS/D3 goodyears when mine finally do run out of tread.

Not really. I started having a flat and at 25 psi the low pressure warning went off, enough time for me to get into the next, and last, gas station before a 40 mile stretch of road without any more stations, convenience stores, houses, pay phones, cell service, people, or other cars.

Re: Tire Pressure Sensors (Sorny)
Here's the web site for the manufacturer that makes the sensors for GM:
http://www.schraderelectronics.com/b...cation_id=1044
Here's their spec for the new Generation II transmitter: "Pressure measurements up to 150 psi with 0.2 resolution and (+/-) 2 percent accuracy..."
The old version, in the current and earlier C5s, was accurate to, I believe 5%; meaning that a 30 lbs. tire could read as much as 28 to 32 lbs.
Also, since the computer gets the barometric reading from the PCM, there is a variance in that loop as well.
Nevertheless, most of the time my sensors agree with the manual measurement , and you can't beat the convenience or safety of knowing when thinks start to leak.
