On the assumption that there are five studs and not four (otherwise measurement would be very easy), the pcd is 1.701 times the distance between two adjacent studs. If the pcd is 112mm the distance between studs should be 65.83mm.

Thanks for the replys
I have tried the center didtance of two studs (not didtance between) and get 2.572" not 2.591" (65.83mm) I have machined up a template to 112mm using Zeuz tables to position the holes so will see if this fits Thanks, J

Just a quick update.
The 112mm template I made just fitted, but was a bit tight, this was probably due to the holes being 9/16" so no clearance on the threads. But with a little more measurement the problem became clearer, as James suggested a dim of 2.591" should be obtained by measuring the centers of two adjacent studs. The pair I had previously measured were 2.572 which is what was throwing me. Measureing all 5 pairs I got 2 at 2.59, two at 2.58 and one at 2.57, so the studs are a bit out but 112mm seems the right size. Hopefully my clients split rims can be salvaged if he gets them rebuilt with new billet centers to the right spacing. Thanks, Jason
