Exact quoted value on the 2500 (DJ) page: "Bolt Circle: 8 x Ø165.1 mm". Same page: "M14 Lug Nut 06511418AA Steel Wheels" / "M14 Lug Nut 06509422AA Aluminum Wheels"; wheel rows verified verbatim from the extraction: "17 x 7.5 Steel Painted [S4A] 1XA75TRMAA 40.1 3500 WDA", "17 x 8.0 Cast Aluminum 1XF 6CV28TRMAA 29.1 3200 WFZ", "18 x 8.0 Steel Painted - S4A 1VU98TRMAC 43.7 3500 WBN", "18 x 8.0 Steel Chrome Clad / SZ0 1UD26TRMAC 45.2 3500 WHB", "18 x 8.0 Cast Aluminum Polished - AAA 6MP64TRMAA 30.0 3500 WBE", "20 x 8.0 Cast Aluminum Polished [AAA] w/chrome inserts 6MH98TRMAA 30.0 3500 WH3", "20 x 8.0 Cast Aluminum Polished - AAA 6MH99TRMAA 30.0 3500 WJR", "20 x 8.0 Cast Aluminum Painted [RFX] 6MH99TRMAA 30.0 3500 WF3", "20 x 8.0 Cast Aluminum Polished with RUW pockets 6MS04TRMAA 30.0 3500 WRP", "17 x 7.5 Steel - Spare E-Coat 04726268AA 40.1 3500 WF1", "18 x 8.0 Steel - Spare E-Coat 68090830AC 43.7 3500 WKN".
