Global standardization of wheel attachment

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

With the launch of the 2011 C-MAX and now the 2011.25 Focus, the diameter of the wheel nut holes  has been reduced from 21 mm to 14.75 mm  .

The reason for this is that Ford is standardizing its wheel nuts  and plans to implement this globally at a later date. The global standardization process will reduce the multitude of wheel nuts available worldwide to a minimum.

At present, however, the conventional wheel nuts are still being fitted for steel and alloy wheels. At the time of going to print, the globally standardized wheel nuts were scheduled for introduction in mid-2012. Further information on using the globally standardized wheel nuts will be available at the stated time.
