Wheels that are spec'd for the G30 (new 5 series) or G11 (7 series 2016 and newer) should have the correct lug pattern, spacing, and off-set to use. TPMS initialization is done via iDrive. Seems to me that if this is something you want to do you should rely on a qualified BMW-savvy shop or trusted BMW Service Center. Too many tire jockeys are not equipped or trained to handle this and saving a few dollars up front may cost you $$$$$$$ in headaches very quickly!

 

The only thing you would have to code is if you were adding or removing TPMS. You should not need dealership trip.

 

No dealer trip needed. I just swapped my 759i summer wheels for 668M winter wheels. Unlike the F10, I didn't have to do anything to reset the TPMS. The dealer (or supplier) will need your VIN when ordering the TPMS. I had an independent shop mount and balance my winter tires on the 668M rims and install the new set of TPMS and when I got home I just swapped the wheels myself. I was looking for a TPMS reset and customary drive around the block for the car to read the new sensors but it didn't seem needed on the G30.

 

Thanks. Did you / can you use the same mounting bolts to mount the 668M wheels as the 759i's? I assume there's nothing special about the size of the bolt head, for example, that makes it wheel specific. Sorry for the dumb question.

 

Same bolts. The only time you may need to go with longer bolts is if you use wheel spacers. The 668M and 759i use the same bolts.

 

Hello guys,

fast question from my side. I bought new sensors off eBay for my winter tire set and I have been reading the TIS where it is said that programing is needed. When I bought the sensors I did not sent my VIN or anything the the seller, thus the sensors were not preprogrammed to my car (if such thing is happening at all). What is needed to be done? I want to avoid mounting tires on the wheels and afterwards having them dismounted because I need to do something with the sensors :dunno:

If the case is as above, just swap, drive and the system will automatically catch them I am just curios, if somebody can explain how is this happening and how the car each sensor's location.

Here are the links of the explanation in TIS which I found:
-> Wheel electronics
-> Tire pressure control

 

Sensors are not pre-programmed to car; that is reserved for ECU's like Kombi (DIM) and HU_NBT2.

You do need to change vehicle coding so car knows hardware changed. You add option 2VB and VO code vehicle.

 

Thanks! I have already the tire pressure monitors, I just wanted to build winter set of wheels 662M. My current set is 759i and it has already the TPMS and they work perfectly.

So overall, nothing is needed, just install, mount tires and drive off? :angel:

 

Question, sorry if it is stupid. But when you mount another set of wheels with different TPMS, or even swap out your existing TPMS, how does the the car/idrive know which sensor went where, ie sensor #1 is now front driver vs passenger rear.....

 

The obvious answer is by time.
It doesn't care which one is where.

 

How is this obvious? Of course it cares, because in iDrive shows you the exact tire with the exact pressure/temperature.

I have seen a Chrysler video where the newly installed sensors were initialized by putting magnet to each sensor in a sequence and this is how the system knew which is which. Having the magnet next to the sensor would break the wireless connection and the car would see that now senor X is not visible => this is Tire X sensor and once you remove the magnet it gets visible and assigned - just thinking out loud:dunno:

I would assume here we have similar approach, but it is just automated.

 

I believe that I have read that wheel sensors***8217; locations are identified by time delays, and that a number of start-ups is required.

A moment scribbling on the back of an envelope gave time delays proportional to Distances, with Distance about the width of the car:
D/2 and D(SQRT(5))/2 and D(2/3) and D(SQRT(5)

So I think that the receiver needs only to be located away from the center lines of the car and the order in which the delayed pulses will arrive. But that***8217;s some subtle cackalatin***8217;!

I thought I read that also.

This appears to indeed occur. The info in post #13 (from the TIS) mentions that once the sensors leave "standby" mode (when speed reaches 18 MPH (30 km/h) the sensors start to transmit data in "defined cycles".
