Wheels are lug centric. Each bolt exerts several tons of pressure on the hub according to an engineer on another forum. The centre bore is there to align the wheel so the bolts can centre it properly with the countersink. It needs a little bit of leeway to do that. I took the .25mm all round off the hub using my Dremel and a sanding belt to finish them, when fitting GT/156/147 wheels to our 75 recently. It worked perfectly.
