411 wheel nut size

[sjp63]

I wanted to know because I have a set of wolfrace Britannia/Beaufighter alloys that I want to fit to my 411 and need some nuts. There are various nut suppliers on the web with sleeved nut designs and tapers and some sell "wolfrace sleeved nuts"

I just need the thread size and other dimensions to see if they have the correct ones.

BTW I measured the wheel holes and I get 17.2mm dia hole and approx 6mm sleeved depth before the taper starts.

Other than that a part number or a second hand set would do!

Also tyres......

411 = 205/70/15

Britannia etc = 215/70/15

Using a tyre calculator the 215's are noticeably larger diameter

215/65/15 gets me back to the same diameter as the original 205/70/15

Any comments on this??
