I've never owned a car with a tire pressure monitoring system before. What iw as wondering is I planned on getting a set of wagon wheels (read: cheap) to mount Kumho V710s on for autocrossing. So I was wondering about these possibilities:

1. If I were to just mount these wheels obviously the monitoring system would not have anything to read. Would the DIC be beeping at me or anything about no signal? And if so, after running a day with these wheels and then re-mounting my old wheels will the sensors work fine or would I need to re-calibrate?

2. Lets say I get wagon wheels with sensors, if I were to mount them would I need to go through the whole calibration process, just to go through it again if I mount my stockers back on after the race day?

Thanks!

I have 3 sets of wheels. Road coursing, drag racing, adn street. I only have sensors in my street wheels. The computer will show an error without the sensors, but it will relearn your street wheels shortly after switching back. You have nothing to worry about except for having fun and storing lots of tires.

Does the DIC make that annoying beep? one run it said low washer fluid and beeped at me, kinda screwed with my concentration....

On the C5 Just clear the errors and you won't have ap readings. If you want the TPM to work then get some sensors for the track wheels from NAPA for about $50 each. One thing about having the TPM system function on the track you will get a warning for over inflation at about 40 psi.

do I have to re-calibrate it each time I switch wheels though?

Definitely on the C6, and the new sensors also seem to require the Bartec tool as nobody has been able to make the magnet trick work with the new sensors. (No idea if NAPA has the "older" sensors.) Also, consensus on the C6 is that you can't run for too long without the pressure sensors or the computer gets involved in negative ways...

If you use several sets of wheels with TP sensors then on a C5 you would need to re-learn each time you switched rims if you wanted the set on the car to provide air pressure readings. This would take a couple of extra minutes each time you switched wheels. The magnet works fine on C5s.

I also have mulitple sets of tires for track and race events. Only the streets have sensors. When you put the sensorless track wheels on the DIC will display tire pressure monitoring system error. Just reset and all is fine. No beeps. clicks alarms or parts flying off the car for the whole day or weekend. Once you put your street tires on with the sensors, the pressures will display as before after a few minutes, no recalibrate or relearn required. been doin it for 3 years no issues

Some tires work best at 42-44 psi HOT, so the TPM is a pain in the arz if it goes off.

Another one tracking with Z06 wheels and no sensors on a C5 coupe and I switch back to stock wheels between some track days. No relearn is required. However, as to wagon wheels, I don't know width compared to Z06 which are 1" wider at both front and rear than my '02s. That extra width on track makes a huge difference in lap times compared to stock size tires. I run 275/295 f/r on track and it really helps grip compared to 245/275. Used Z06 wheels are available since many switch to after market upgrades on the C5 Z06. FWIW

that's why I don't have wheel sensors in my track wheels.

BTW: I've never had to reprogram sensors for my C5 or C6 Z06 but I did have to reprogram them on a friends C5 and it is pretty easy. You have to have a decent size magnet and a helper.

Make sure you ask someone else if you have a c-6. I went to the track two weeks ago with a sensor that was not working properly. the car would not go into competition mode and the active handling was in its most sensitive position. as a result I fried a the left brake rotor, calaper and of course new pads. I assume if you had no sensors the active handling would also be full on.

I have a C5 so the C6 problems wouldnt be an issue. Thanks for the help!

Gary2KC5

I didn't have any issues getting into comp mode without wheels sensors in (I have a C6 Z06 though, maybe it's diff). I thought it strange that the DIC displayed a reading without them in though.

BTW: was it a front or back, and was that the only corner with a problem?

Were you parking next to your street wheels in the paddock between sessions? Folks are saying the last known pressures might be displayed for an hour or some number of miles, too... so if you swap on tires and drive to the track you may have more issues.

As I said in another post recently, nobody really has good consistent data about the TPS and the C6. It seems to be okay for some folks and throw the computer into fits for others. :-(
