Any of you have this issue or ever hear of such a thing? I put R888R's on my 765 (on all 4 corners, on OEM wheels, with OEM TPMS sensors). The TPMS stopped working, after being at the dealership multiple times, replacing the sensors, they claim they put OEM tires (Trofeo R's) on my wheels and the TPMS started working. To me this makes no sense whatsoever????? Anyone else have this issue?

I take it these don't have the sensors inside the tire like the Artura, so no, that makes zero sense. I've had R888R's on my 570s and 600lt no problem. I'm not sure what to make of that one. I don't think they're telling you the whole truth. Were they the same exact sensors you had on your car from the beginning? Maybe when they mounted them the TPMS sensors weren't your originals and were not programmed and then they reprogrammed them after putting it back to OEM tires?

 

[houstonT]

Correct, they are standard TPMS sensors...I suppose my only option is to get OEM tires and see? If anything, maybe swap the fronts to Trofeo R's and leave the rears as R888R's since so many people I know run OEM front with R888R rear. Since the module that reads the TPMS sensors is in the front fascia, maybe OEM fronts only? None of it makes sense...

Something is definitely not right . 765LT has the same sensors as 720S . I've had R888R on all 4 corners with oem wheels and oem tpms sensors . TPMS worked fine on my 720S . Tires have nothing to do with TPMS sensors .

Have them reset the "tire type" through the cluster and re road test

 

[Bogan69]

Yep. Complete BS. Ive have different tyres on both my McLaren's and never an issue. TPMS always works.
All these tyres have been done at my local tyre place so not even at McLaren.
Cant believe the crap they try and tell you.

The reset to different tyre type wont make any difference. All that does is change some parameters like what temp to turn from blue to black on the dash and such. Low setting sets the temp to be ok and out of blue at approx 15c, Corsa at 25c. Not sure what trofeo is Cant remember the exact number. But thereabouts.

The tyres are just dumb rubber. No embedded chips to talk to the sensors. So no way tyres can affect the working of sensors.

 

[houstonT]

They are inferring that the R888R's have more steel in the belts than the OEM Trofeo R's and that's what causing interference resulting in TPMS not reading. Also, I have several friends running R888R's in back and OEM Trofeo R in front with no issue. I asked the dealer if the front or rear was giving the error code and they told me rear.....(shaking my head).

That is possible - I had that on my Nissan GT-R, I bought a tool to put the sensors into a learn state and then used an Ecutek cable to tell the car there were new sensors. It was a bit of a pain getting the tool to hit the sensor with it's beam on tires with a thicker sidewall and occasionally I'd lose a sensor while driving. It may have been a weak battery in the sensor though.

That was pretty old sensor tech - I can't imagine that 10 years later there would be any issues.

Maybe ask a tire shop if they have a tool to read the sensors ID and battery voltage? That will rule out the sensors themselves.

Or just go for a long drive - maybe the issue will disappear all by itself.

Completely bogus. Tires will not affect this at all.

 

[Excelsior]

I have had 4 sets of R888R's on my Mac's (12C, 570S, 600LT), never a problem. Brooks has had them on his 765LT and 720S. Something else is amiss.

 

[houstonT]

I agree with every one of you by the way....but they are unwilling to take any additional steps. I suppose the ONLY option I have is to get a set of OEM tires and try. SMH

Quick update...I sent the 765LT to Jotech Motorsports, a LONG time friend (Kenny) owns it and when he heard the explanation that the tires were causing the TPMS to not read, he also thought that was a non sensical explanation. Methodically he did the following:
Put new TPMS sensors on and programmed them to the car. Didn't work.
Borrowed a set of OEM wheels/tires/TPMS and put on my car. It worked.
At that point, we knew the TPMS module was NOT the culprit.
He then put my R888R on the other OEM set. It worked.
So it can't be the tires.
Best guess at this point...my car came with OEM silver wheels. I asked and paid the dealer to paint them black for me. Dealer did that. Our guess is that the vendor that he used to paint the wheels did too many coats of black paint and too many coats of clear and for some reason that is interfering with the TPMS reading. So, he is having the wheels stripped and will use powder coat rather than paint. Keeping my fingers crossed, as it can't be anything else at this point.

Will update this thread once conclusion has been reached.

I would lean more towards the new TPMS sensors being either incompatible or faulty. There's no amount of paint that could interfere. Think about how thick the tires and rims are. The better explanation would be the new TPMS sensors are either non-oem knock-offs, incompatible, faulty, not programmed, or the wrong frequency or region.

 

[invisiblewave]

If the paint is metallic, it might be RF opaque.

 

[houstonT]

You would think EXCEPT for the fact that the dealership replaced the sensors with new OEM ones 2 times (the second time because I insisted) and Jotech tried aftermarket replacements that have worked on countless other 765's they've done wheels/tires on. So it isn't the sensors.

Looks gloss black......anyhow, end of this week, they will be redone powder coat gloss black, then we will know for sure.

I know he doesn't think there's an antenna, but there's a thread on the 12C forum that talks about a sensor/antenna under the transmission. I have a diagram for my other car showing an antenna for each wheel connected to the controller.

 

[Excelsior]

If the paint is metallic, it might be RF opaque.

But it doesn't travel through the paint or the rims. The sensors pick up through the tire. You've got rims that are aluminum, magnesium, carbon fiber, they all work just fine. Some are powder coated, some are painted gloss, some are painted metallic. The signal doesn't travel through any of the paint, unless they were painted with F-35 stealth paint that somehow absorbs the RF signal, it just doesn't make any sense. I would lean more towards the technician not programming them correctly, both times, or they kept ordering the wrong frequency.

OMFG y'all......so, new TPMS sensors.....no go.....strip and re powder coat wheels......no go......literally the only thing that works is OEM tires. I even bit the bullet and bought a new TPMS module....no go. Yet there are multiple folks running the R888R on the rear with no issue??? I'm at a loss.

That is absolutely mind boggling... I have PC'd wheels and Michelin PS4S's no problems... I was thinking about the R888's but now ya got me wonderin'....
