need help to identify my rims

[Patrick LANÉELLE]

Hi guys
I've bought a nice set of 10" and 8" rims (15" Ø)

it's central nut fitting + 6 studs.

it's very difficult to catch the correct measurement with a reliable accuracy as it's deep in the rim. The caliper is fighting with the side wall...

is any body can help me to identify theses rims, and the details of the fitting?

approximatives values are:
- 6 studs Ø12.7mm (1/2") on an approx diameter of 108-109mm
- inside bore on disk side around Ø82mm
- inside bore on nut side around Ø72mm

Help !?!?

all the best

Same as sold by vintage wheels (?)

They look like SPF wineglass wheels. I believe Vintage Wheels sells the same wheel as their web page says "direct fit for SPF".

Thanks Lee, you're right !

they wrote:
Set of 4 HB01 wheels
2 x 15 x 8 backspace 3.6 in
2 x 15 x 10 backspace 3.6 in
pin circle 6 on 4.25in
center bore 83.4mm

then 4.25 x 25.4 = 10.795mm for the studs organisation

something seems strange to me.
on my rims the stud housings are very small; Ø1/2" ! ! !
on vintage wheels website they're speaking about Ø3/4"...
even if I use M10 studs, 1/2" is 12.7mm so if I machine custom nuts to fit on, they will be only 1mm thick....not a lot..
a solution would be to oversize these 1/2" housings, but difficult not to loose the center...

I'm a little confused about your studs. At least on SPF 1/2" pins (studs) are fastened with nuts on back side of hub. Where would the nuts for your studs be located?

I was thinking to fit custom nuts on the studs (solutions 2) but studs are M12 and holes in the rim Ø12.7...

But if I have fully understood, you're speaking about the solution 1; am I right?

Hi, using the values founds on vintage wheels and the one I was able to catch on my rims, here is the result with a solidworks help:

do not hesitate if you see something strange !

So I have design an adapter that I will 3D print with plastic to check if everything is correct or not:

Yes Patrick, solution 1 is what SPF does. Solution 2 looks more difficult and less satisfactory.

Nobody for the thickness of this flange?

on my side, I have 3D print my control part:

and it fits perfectly my rims ! ! ! ! :

thanks for your help !
