Hi together, I’m looking for wheels and tyres for the winter (Forester SJ, MJ 2018, Platinum). According to the website of a tyre shop, no RDKS sensors are required for the passive tyre pressure control system (RDKS):https://www.felgenshop.de/source/skin/default/img/fsv2/RDKS-Passiv.png On the other hand, with the active RDKS already:https://www.felgenshop.de/source/skin/default/img/fsv2/RDKS-Activ.png Is a passive or active RDKS installed in the Forester SJ (MJ 2018, Platinum)? My Forester shows that In the display no tyre pressures on (unless I have never checked/set this before), so that I go out of a passive RDKS. Then I would not need to order any sensors when ordering winter bikes (wheels and tyres). Correct?EDIT: According to the list of the ADAC, the Forester IV (SJ) has a direct measurement by means of a sensor. So I have to order some extra ones?EDIT-End Does your aluminium or steel rims recommend in winter? What about snow chains? Where can I find information about which snow chains? e Wheel dimensions for my vehicle must be adhered to (boreing, press-in depth etc.)? In the registration certificates Part I and II and in the Subaru Forester catalogue (technical data) I could only find the tyre dimensions (225/55 R18 98V). Thank you for your help!
