Rubber valve stems with TPMS
If have a 2007 MCS with Rubber valve stems which come with the old TPMS, I currently have the R97 Flame Spoke wheels. I want to switch to the OZ Ultraleggeras in 17 inchs. From what I have read here if I keep my original tires (205/45/17 RFTs) I will not have rubbing issues even if the offset is Et37 instead of the original Et48.
My question is will I be able to change the TPMS to the new wheels? Any of you guys with Ultraleggaras done it? Thanks

From another thread:
Looks like you have the passive system.
OT: It's really annoying that MINI does these mid-model changes - makes everything a big guessing game.:impatient
Um, I'm not sure who you are speaking to, but if you have an early-build R56, you have a "passive" flat tire monitoring system, which uses wheel speed to deduce if there's a tire with lower pressure. Those wheels have NO sensor in them. The car just watches the speed of each wheel and compares it to the others. So you can use ANY stock or aftermarket wheel, with or without the sensors inside, and the passive system will still work fine.
Valve stems have always been available in both rubber and metal, so a metal valve stem is not a guarantee that you have a pressure sensor inside your wheel. On the other hand, the sensors can ONLY be used with a special metal valve stem, so if you have rubber valve stems, you don't have the sensors.
The ACTIVE TPMS uses the sensors pictured above, and requires the sensors be in each wheel that's on the car. This system became standard on the MINI starting some time...late this past summer, I think? If you have the active system, you will have to have sensors in any set of wheels used on the car, or it the car will complain.

Check the production date of your 07 as it was a mid-year change. It's a quick call to your dealer.
