Summary

In 2016, mercedes-benz released a new 2-pc flange nut wheel fastener (mercedes-benz p/n a 000 990 53 53) which is taller and has a larger washer diameter than the previous 2-pc flange nut (mercedes-benz p/n a 000 401 18 72) used for model years 2007-2015. Due to the change in height of the 2-pc flange nut, alcoa wheel p/n 25080x cannot be used in both the outer rear dual position and inner rear dual position with the new 2-pc flange nut as this creates a sub-flush thread engagement condition. It is recommended that 2-pc flange nuts are at least flush with the end of the stud. This communication explains how only one alcoa wheel (p/n 25080x) may be used in the dual configuration to provide adequate thread engagement and fastening of our wheel.
