Hello forum, I ask here my first question in the hope to get competent help. My name is Sebastian and I drive a motorhome on Ducato 244 4×4 base with so many modifications that the side sheet is already almost full, so it is not a vehicle from the pole. I currently drive 245/70 R16 tyres on 7×16 aluminium wheels, but these rims have not been available for a long time. Since it is a long distance travel/offroad vehicle a spare wheel in tyres would be For the desired tyre size, rims of at least 6.5″ width are prescribed. I have the following options: -Buy an aluminium rim which then visually does not match the others and is also only 6.5″ wide. (I would like to avoid this is Plan B) – Buy steel rim which 6.5″ wide are but have a too large center hole, these then center over the wheel screws or can one use centring rings as with aluminium rims? -On the original steel rim which is only 6″ wide I ask for your opinion, experience and knowledge about the two preferred solutions, i.e. steel rim too narrow or with inappropriate middle hole. Please no comments with: why not simply reduce tires with the same circumference, you will not get that through the TÜV (no one will be interested in what is “allowed” if I mount my spare tires in Georgia) or centring on steel rim is not allowed… that was not the question, the question e was “happens” and not “happens”. Many thanks and greetings, Sebastian
