2000 1.4 alloy wheel fitting - shug119
Hi, I got my son new alloys ( second hand ) when I tryed to fit them I noticed on the existing wheels. On 3 wheels the locking nuts were flush and on 1 wheel they were sticking out about 10mm. The flush wheels had 2 counterbores in them then a taper, the locking nut looked as if it was locking on the 1s counterbore, not the taper. The other wheel had 1 counterbore then a taper, the locknut was locking on the taper.

The new wheels have 1 counterbore then a taper. But the thread is sticking out about 12mm.
Is this enough to hold the wheels secure.
I can put a second counterbore in the wheels at work or I can m/c the taper on the locknuts back to alow he thread to come through more.
How mutch thread should be out.

Gratefull for any advice
Cheers Shug.
