RoadRage786 Posted May 6, 2019 Share Posted May 6, 2019 Long story short, I have a 2015 Base MKZ with the 18" wheels. I was looking to get a set of 20" 2017 MKX wheels. Both share the 5x108 bolt pattern, 63.4 hub size.....my 18"s are a 55mm offset and the MKX are a 52.5mm...i called a few shops and all swear my offset is "in the book as" 35-45mm. All state that its impossible its 55mm....In theory if it is 55mm will the 52.5mm fit? Quote Link to comment Share on other sites More sharing options...
drolds1 Posted May 6, 2019 Share Posted May 6, 2019 All 2015 MKZ wheels are stamped "ET55" on the back. This means that they are 55mm offset. Quote Link to comment Share on other sites More sharing options...

In addition to the information drolds provided confirming the MKZ wheels are 55mm offset, and assuming the lug spacing/bolt pattern/centerbore/hubsize information you have is correct: If the MKX wheels are 52.5mm offset, and if they are the same width as the MKZ wheels they will fit...in theory. They will stick out 2.5mm further than the MKZ wheels. However, you also need to know the width of the MKX wheels. If they are wider than the MKZ wheels (I do not know the answer), it changes the fit. Find out the width of the 20" MKX wheels.
