Hi, I have here an Audi A6 4F (0588 / ABA) in S-Line (so a little deeper) with the following instructions in the operating manual: Quote: The use of snow chains is only allowed on certain rims/tire combinations for technical reasons: rim/ET/tires 7Jx16 / 42 mm / 205/60 7Jx16 / 42 mm / 225/55 7Jx16 / 42 mm / 225/50 Use finely structured with max 13.5 mm. Now my previous owner has thought he needs 18 rims. Therefore I have the following on it: 8Jx1 8H2 / 45 mm/ 225/45 The attached report (RA-000337-C0-015) on rim ABE 45998 states: Quotation: The recipients must be pointed out that snow chain operation has not been tested, unless the use of snow chains is allowed by another edition in the report. I do not see another edition. Can anyone help me what this means for me and my snow chain project? My lay derivation: – The socks are wide just as in the factory hand book – The 225/55 R16 have almost the same wheel diameter as my 225/45 R18 ( ) – That means it should turn around the press-in depth. I am 3 mm further outside. Would I be still far enough away from the fender with 9mm snow chains, because 13.5 mm would be allowed? Thank you in advance!
