Old thread but exactly the people i the know.
One of my EARS rims has a shamfer in the inserts as Warran shows above, i didn't notice this before they went for referb and i only noticed when the fitting as the wheel nut doesn't go on as far as the other 3 - as its angled for a wheel nut is this going to be fine or should i remove the insert and run with 4 Grp4 nuts i have here
