About 6 months ago I replaced the wheel studs for longer ARP ones and changed the oem wheels to aftermarket ones that have tapered seat wheel nuts, what I didn't catch on was that the oem wheels don't use the same type of seating.

My oem wheel nuts no longer fit (due to the long studs, I throw them away too)

Does anyone know the seating type or knows where to find a replacement that is either open ended or can at least have 45mm of thread engagement?
 
OEM wheels use taper seat same as aftermarket wheels. If you need 45mm of thread inside the nut, then you need open ended nuts.

Odd then, not sure why the tire fitter said he couldn't use my tapered nuts
 
Also why wouldn't your OEM nuts fit your longr ARP studs? I assume that the longer studs are for spacers, so if the spacer is the same size as the difference between the OEM studs and your ARP ones, wouldn't the OEM nuts still fit?

No, I got 3" studs, a 10mm space. That so leaves loads of threads, the oem nut is too short for that
 
Managed to get some oem nuts to compare with the tuner nuts

that looks like a standard 60deg taper on both nuts.
