TPMS Question

[DINANM3]

I currently have runflat tires with TPMS.
I want to switch to non runflats on larger than stock wheels.

My question is how does this mod affect the TPMS and what do i need to do to the new wheels if anything to avoid problems?
If I just put regular wheels on will the TPMS light come on and think i have a flat if i dont.
Do I have to install TPMS on the new wheels and if so how do you do that?

if you switch to non-RFT, you'll need to get a set that has TPMS already built in. I got my winter setup from TireRack and you can purchase the sensors from them and have them installed when they mount/balance (if you're buying a whole package).

the TPMS light will come on each time you drive without the sensor and it becomes kinda annoying.

Hmm interesting, I ran different wheels all the time and didn't have issues with the sensor light coming on.

I ran replicas on the X and I run 19's Non-RFT on the E60 and don't have an issue with the lights.....

I assumed he was talking about TPMS in his 3 series, since I went thru the exact same thing when I switched to a winter setup w/o TPMS at first.

The earlier model e60s had a different version of monitoring tire pressure. The newer cars have a special metallic stem value that transmits info to the OBC. If there's no TPMS sensor, then you get the error msg.

Ahh, ok, haven't had a 3er since my E46 which I didn't run into issues either. Guess it is a E90 thang.

The system you have is the same system my 2006 X5 has. It works with the abs sensors.
The system my 2007 3 series has is the direct TPMS. It uses a sensor in the wheel. 90% of 2007 bimmers have them in 07 and i think all will have these by 2008 or 2009. I guess its a new law that the USA passed. I heard though that other countries will keep the abs based TPMS system.

UNless you have metal valve stems, any wheel will be fine.

sorry dumb question... so does that mean that changing to aftermarket non-RFTs will not cause any problems or errors with the 07 x5??

if there's an error light on the dash can the TPMS be disabled to lose the error light???

Hi I currently own a 05 X5 3.0 w/ TPMS.... 17" OEM wheels, I am thinking of purchasing Conti Crosscontact LX 255/55/18, I already have a 18" OEM Bmw wheels, my question is will the TPMS still work if I switch the tires & wheels ? or do I need to modify anything ? Also How do you rate the Conti ? my stock MXV were really bad in the Rain..... thanks for any inputs.....

05 X5 with OE 17's and TPMS--changing to 19" 132's. I believe the TPMS is the earlier version until you get to 06, that is, a quick reset of the liht after install should be OK. The 17" OE wheels do not have sensors on the wheels, correct?
