That is a good point to bring up Andrew. 
I should have mentioned that this wheel is for a slow-speed wet grinder and only runs at 90 RPM. I wouldn't want to be anywhere near a wheel of this size at a high RPM. It is 10 inches (250 mm) in diameter - 2 inches (50 mm) wide and weighs 10 lbs. (0.71 stone) so I am more afraid of dropping it on my foot than anything else.
I just wanted to true up the edges of the bore so that the weight of wheel didn't cause it to settle on the drive shaft into one of the chipped spots on the edges and induce any run out / wobble problems. As I mentioned it probably wasn't necessary to do at all, but it gives me piece of mind regardless knowing the bore is as true as possible. I had to make myself new hubs for the wheels on my 6 inch Harbor Freight carbide grinder thanks to the sloppy fit of the bores and multiple voids in the cast aluminum (aluminium) factory hubs. Out of the box that grinder would vibrate itself right off the workbench if it wasn't bolted down. No bueno.
