1987 GN Wheels studs thread size

[GNONYX]

Hi All, Would anyone know what is the original wheel studs thread size?
I know the original studs nuts are metric, but I don't know the studs thread size. I just finished sanding and polishing the three piece rims which were dull and started to show some pittted spots. I had these rims for about 21 years and I search everyplace and everywhere to replace this type of rim, but with no luck I reconditioned them myself. Many hours and weeks went by to refinished these three piece Aluminum Rims. Now I can install a set of 245/50/16 rw tires and 225/50/16 fw tires.

i find most 5 point wheels boring but i'm really impessed with those and the center cap fit. who makes those if you don't mind me asking?

I measured the center rims diameter to make a custom center hub, and also with the metal self adhesive powder 6 logo were purchased individual through EBay years ago. The wheels are about 21 years old, and stamp (Japan) inside the wheel rims. discontinue
Thanks for the quick reply; now I can replace the nasty pitted chrome wheel nuts with the correct wheel thread nut size.
