Got the 2017 Latitude AWD with the Altitude package, comes by default with 18x8 wheels. I want to buy an aftermarket wheel as a full-size spare with the exact same specs, but Jeep CS and the dealer refuse to provide the full specs (nuclear codes anyone?) Can anyone confirm what are the real specs on those wheels? MOPAR item # 6EQ47MX5AA Need to know accurate specs for the center bore, offset and bolt pattern. Thank you!
