Wheel balancing - Centre (hub) or stud

Not that I'm aware of.

We are split into two camps

Those of us who are practical engineers insist that the tapered nuts, and the fact that the wheels don't jam on solid with alloy corrosion means that they are stud centric and the hub ring doesn't touch the wheel. The steel wheels should be stud centric as the centre hole clears the ring on the hub

Those of us who are used to modern alloys that you have to either beat off the car with hammers or slacken the nuts and roll backwards & forwards stamping on the brakes until they come loose insist that they are hub centric- they must be if they are jammed on the hub rings..... (My electrocar had all 4 wheels jammed on solid when I got it, and had to have them "persuaded" off, yet it has tapered bolts)


As far as I can tell, when Suzuki finished the alloy wheels, they machined the centre hole & flange concentric with the nut tapers (It is no more trouble to set the machine up to do the job properly than to set it up wrong.... plus there will be unnecessary strain if the wheel locates by the hub and then the stud tapers are way out when you tighten them up ), so it doesn't really matter which way you balance them!




 

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there :)

If the lug/bolt holes have a tapered seat, the wheels are "lug centric", if the lug/bolt holes have a flat seat, the wheel is "hub centric" - if you've ever fitted a "hub centric" wheel to a vehicle, you'll know that there is no disputing this.

When it comes to balancing, it doesn't make a difference, because the center bore is going to be concentric with the wheel rim. Most wheel balancers use a cone to center the wheel on the spindle so they can accommodate wheels with different sized center bores.

Did we ever get a definitive answer for this? 
See @facade's note above.  Particularly with alloys, the machining will all be concentric anyway, so the practical effects of hub vs stud balancing are nil.

In olden times, when machining was done by men in brown coats, it probably mattered more.
