RDC/TPMS on a M235i xDrive Coupé (2015)

Hi!



First post in here and thought I would start by asking you experts about RDC/TPMS.



I just ordered a M235i xDrive and planned delivery is week 51 right before Christmas so will make for one nice Christmas present :thumsup:



When I talked to the sales man about winter tires he told me that if I get winter tires from somewhere else I need to make sure I get the correct sensors/valves to make sure the tire pressure system will work correctly.



I then talked to one of the online stores in Sweden and was told they did not offer this kind of sensors at this point and that I need to find the sensors elsewhere.



I was then told in another place that I can buy them directly from BMW but what I'm still not sure about is how to fit them and what exactly they are? Is it likely if I get the needed sensors from BMW I could ask any tire workshop to fit them for me or does mounting them take special equipment?



And last question, can I pick any rims and tires I like or do I need to make sure to pick rims and tires especially suitable for RDC/TPMS?



Thanks a lot in advance guys!
