I have recentley fitted 360 Forged rims fitted to my Ron Fellows Z06, running 20 on the front and 21 on the rear, and for the first two weeks I had all tyre pressures working and showing on my dash, but then they all stopped and constantly comes up with Tryre pressure failure and all wheels indicate the sign "XXX". I am aware thuis will not cuase any problems but it is annoying and have taken the car to the authorised Chevy dealer who informs me that they have tried to re calibrate the TPMS but as it is inside the rim and not on the outsied as per the standard z06 rims, it cant be picked up. I have spoke to 360 degree forged and they inform me they have not had this problem with others who have fitted the same size rims, but I find it odd, does any one know how to rectify this problem and get it working properly.

On another issue, I have had Calloway coil overs placed on the car, and it has made the ride height site quite high and have gone back to the installer who says they can not lower it anymore, the car looks not right, and with these new rims, the lowering is important for the looks, any advice here, it already has the oem lowering kit on the car, but is sitting too high. it has Calloway adjustbale sway bars which have been tightend up to firm ride, but we cant get it lower as to what it was prior to fitting the coil overs

 

re: TPMS

If *all* of them have suddenly started showing XX then (a) are you sure there are sensors installed at all? and (b) if so, are you sure they were ever configured?

If you do have them in there then you might read this thread:

Re: Callaway shocks (which I have on my car)

The Callaway "coilover" suspension isn't really a true CoilOver suspension like the LG or Pfadt sustems. The Callaway system leaves the stock Corvette suspension in place which means that lowering is still a function of the leaf springs and the stock (or aftermarket) adjustment bolts. So I'm not surprised that your installer can't go any lower.

If you are running 20" fronts and 21" rears then what size tires are you running? If they have an overall diameter that's greater than stock then you will have raised the "lowest possible" point by that amount.

You'll probably need a true coilover system to get the effect you're going for.

Hi Zoxxo,

Many thanks for the prompt reply, and have studied the link you sent, and will now take this to my tyre store tech to read and to see if he can then ammnd it or fix it, and will let you know.

The tyres are Pirelli 375/20/21 on the rear and 285/30/20 on the front.

With reagrds to the suuposedly coil overs I boguht, I will now take the car to the race suspsnsion shop and perhaps even take the coil overs of and get them to prescribe new springs or what ever and bring the car down to a good looking height.

Once I get this sorted and the tpms sorted will post some pics, and thanks again for your valuable help.

 

If you're looking for a solution to help your Corvette look it's best on the new wheel and tire setup you should really look at our new FeatherLight Generations Single adjustable coilovers. Our coilovers were designed from the ground up to get your Corvette the stance you're looking for without compromising ride quality or handling. The adjustments are simple and easily accessible, and the dampers themselves have custom Corvette damping rates built into each unit. The new BOA upper mounting system and the CIRC gas canisters are firsts in the Corvette coilover world and ensure that you're new suspension will perform just as well next year as it does the day you install it.

If you're looking to replace what you currently have with the best single adjustable coilover option available for the Corvette, look no further than the FeatherLight Generation Single Adjustables.

 

Hi

Welcome to the forum!!!

I looked in your profile to see where you live, but there's nothing in there. If you are in Central or Northeast Florida, I'll drive over and see if I can help you program your sensors.

I also was looking to see what year your Z06 is to give you the correct part# sensor so you could check to make sure you have the proper sensors for your model year (2005-2009 use one model sensor; 2010+ uses a different one). Again, no info about your car in your profile.

So.....where do you live, and what model year is your car??

It can be very difficult to trigger the sensors when they are mounted deep inside your wheels with bands or a bracket. You need to know EXACTLY where the sensor is in order to get the antenna of the TPMS tool as close as possible to be able to trigger it.

If your car is a 2010 or early 2011 you can trigger the sensor by changing air pressure - so you won't need a TPMS tool.

[hi mate,

Am sorry for the lack of info, I am australian living in Dubai, solong drive for you.

I aprreciate your offer, as I can not seem to get these tpms sensors to work, and I beleive itsa a simple solution but I do not know how to fix it.

My car is a Ron Fellows Z06, build number 318, and has the nesh series running now with 21 x 12 . With 375 on the rear but the sensors are separate to the valve and both located inside the rim.

Have been to the chev dealer who has puuled out the calibration tool and placed near the tyre to try to find the sensor but to no avail, now they are suggesting have someone remap rhe computer and all this crap, whivh I do not want to go down thsi road.

Anyway, no one really here that knows 100% exactly how to fix this and 360 degree forged who made the rims have supplied and fitted genuine tpms and they all worked for around 14 days then all of a sudden one morning they all stopped so when the dealer tells me its the computer not being able to read the sensors I find this hard to believe as they would never have worked but they functioned perfectly for 2 weeks,

Any ideas.?

Regards,

Enver

Aha, an Aussie in Dubai - Crikey, now we've got to figure out where your car came from!!!!!

First of all, your new sensors may have "appeared" to work for a couple of weeks, but until the ID# of each of the new sensors is programmed into the TPMS computer memory in the car they will not be recognized.

The car "remembers" the last known pressures of the old sensors for a period of time - on a 2007 that's about 30 minutes of ignition on time. After that period of time not receiving any signals from the sensors whose ID#'s are the ones programmed in, it finally decides there is a problem and puts the "xx psi" in the DIC, and probably a "Service Tire Monitor" message.

Now - where is your car from!!!!

Was it imported from the U.S., or was it a car built to Euro specs???

I'm pretty sure some of the RF Z06's were built for delivery in Europe or elsewhere outside the U.S. The cars have a different TPMS computer if built for foreign delivery, and they require different tire pressure sensors.

If you don't know for sure the build specs, just take a look at the sticker in the glove compartment. The sticker has a long list of RPO codes, and for a 2007 C6 one of them will be either a "UJ9" or a "UH3" (in 2010 they went to a UJM, and it requires another different sensor).

If your car is a U.S. car it will have a UJ9, and if it was built for foreign delivery it will have a UH3.

Do you know what sensors are in your wheels - did you see them before installation, or do you have an invoice with the sensor GM part#?

The U.S. UJ9 in a 2005-2009 C6 uses a gray sensor with GM part# 25758220.

The Euro spec cars with a UH3 TPMS use an orange colored sensor with GM part# 25758221 (last digit "1" instead of "0").

So.....let us know what TPMS is in your car and we'll go from there!!

Bob

 

Hi mate,

Have done what you have asked, and yes the number ends with UJ9 and the part numbers you have also mentioned match exactly, and I have also purchased 4 brand new tpms monitors from Chevrolet with also the same part numbers just in case, so just to confirm, the number in the glove box ends with UJ9 and the sensors which were fitted by 360 degree forged in the states appear to have the same part number and I also have purchased 4 new ones with the exact same part number as you have specified although have not fitted them as the others which are on the wheel seem to have the same part number, what would you suggest from here my freind?

Hey and thanks so much for taking the time to help me, after I finish this problem then I may ask for help with adjustable coil overs that I can also adjust the ride height so i can sit the car nice and low.

Thanks again,

Cheers

 

If/when you get the tires and wheels apart be sure to mark the sensors' positions somewhere on the outside of the rims so that you can tell where they are located when it comes time to program the system. That will eliminate one potential source of frustration.

Exactly what Brian said above....find the sensors first.


From what I have seen in the past, the 360 wheels mount the TPMS sensors just like OEM....but they mount it on the inside of the wheel, so look for two sets of valve stems on the wheels.

If the car was an export car it will use a different sensor than one here in the states and they are not compatible with the system in the car so they would not re-cal nor would it read them.

 

Without a pic of this wheel/tire combo.. I regretfully cannot give insight.. lol

 

Excellent!!! If you have the UJ9 TPMS then it takes the gray sensors (part# 25758220), so it sounds like you're all set!!

Now for the problem programming them!!!

The TPMS tool required to trigger the sensors (force them to transmit their data) is very low powered. The antenna of the tool must be within a couple inches of the sensor in order to trigger it. It transmits a VLF signal (125 kHz) and the antenna must be put on the rubber sidewall of the tire to shoot the signal through to the sensor.

The valve stem is attached to the sensor, and on stock wheels you know exactly where the sensor is and can put the antenna of the TPMS tool on the rubber sidewall right next the valve stem.

With exotic aftermarket wheels, the sensors may be mounted deep in the wheel where it's difficult to get the signal from the TPMS tool to trigger the sensor. Some owners have found that putting the antenna of the tool on the tread of the tire gets it closer to the sensor.

At any rate, you need to know EXACTLY where the sensor is mounted inside the wheel in order to get the TPMS tool antenna as close as possible to the sensor.

Sometimes you may have to break a bead on the tire to stick the tool inside the tire to trigger the sensor.

Also, the TPMS tool needs strong/fresh batteries so it transmits the strongest possible signal.

Good luck - let us know how it goes!!

The video below shows how to put the car into the learn mode and do the programming procedure.

Yes!! I learned this one from experience, too!

does anyone here own and rent/ship around the tpms tool?

 

Just buy your own for $62.33

Here's a link to the cheapest tool out there:
