New rims have different bolt size

[olethalb]

refresh of the m12 - m14 comparison

and the conical vauxhall bolt

is there anyway you can measure the outer diameter of the 'cup' in the wheel?

i'm going to get some measurements of the m12 and m14 outer diameter.

Ole thanks for having a look at this thread again.

gotta say though that that's quite a difference between the M12 and M14 bolts. And my pics where the M12 bolt enters the rim is also leaving quite a gap.
Seller of the inserts isn't replying...

what to do?
