How do I put TPMS sensors on my old-school BBS RK wheels?
Hi all,
A couple months ago, I purchased a 2014 BMW 328d xiT. I have a set of old-school 17x8 et35 BBS RK wheels that have followed me from my E36 M3 to my E90 325xiT to now. The wheel size and offset is perfect for the F31! |

These wheels were made well before TPMS sensors were ever a thing, so they aren't designed for them. Here are some pictures of the inside where the valvestem sits.

I ordered a set of VDO TPMS sensors (5/2014 build date), but it was clear they weren't going to fit. The body of the sensor hits the shoulders of the recess well before the seal makes contact with the seat.

My next step was to give Rudy (our Tire Rack forum sponsor) a call. He said that they carried a set of modified VDO sensors that work on some pre-TPMS wheels, so I ordered a set. When I received them, I saw that they had a notched metal washer and a longer base under the seal. Promising!

About an hour after I dropped the wheels and sensors off at the shop, they called. "Yeah you might want to come over and look at this before we do anything."
The modified sensors did actually allow the seal to just touch down to the wheel surface, but it was just a bit short; tightening the stem collar down pulled the sensor out at an angle from the wheel, and the guys at the shop said that breaking off a sensor would pretty much be a matter of time. So close, yet so far away... |

So I returned the Tire Rack sensors (thanks Rudy!) and wondered if I could strap these in. I've heard of people banding TPMS sensors to pre-TPMS wheels, so I picked up a TPMS strap/cradle kit from Ebay.
That's where I'm at now. The VDO sensors are narrower than the cradles, so the only attachment is the stem and threaded sleeve. I'm not really crazy about that... Do I have any better options that I've missed? |

Thankfully, this story has a happy ending! I spoke to Garrett at shoptpms dot com, who told me that they carry a 433MHz HUF sensor that can be ordered with bases in a variety of lengths. He had me send some detailed pictures and measurements, then he sent me some specific parts for my application.
And they fit perfectly! In the third picture below, you can see the cylindrical base; this can be ordered in a variety of lengths (measured in mm) for each application. (You might notice that the wheels have been powdercoated since my last posts. To make a long story short, I tried to do some DIY curb rash repair and it didn't go well. I don't want to talk about it.) |

thats a lot of work to fit 17s on an f30. appreciate the time you spent to research your options and fit sensors but i honestly would have upsized to at least an 18 and sold the rks. its basically a saab wheel.

I registered just to say how awesome this is, and how useful the information is to me, as I'm also thinking about mounting some vintage wheels on my F30.

Hi Stevie, My invoice from shoptpms dot com shows the following: UVC0027SET - BMW, Mini Huf Intellisense TPMS Sensor Set HufRDV004K - Huf RDV004 Valve Stem Kit If you give Garrett a call at 714-692-8767 (if he's still working there), he can make everything super easy for you. It's good to have someone supporting you when trying to get specialty stuff like this figured out. - Chris |

I am an E34 guy and yes, agreed, RKs were so hot back in the day.
