Hub centric wheel bore tolerance??

mbbx5 · 01-05-2010, 09:41 AM

Does anyone know what the tolerance is for hub bore on OEM BMW wheels? I searched the internet and came up with one answer but the poster did not state where these numbers came from:

hub tolerance: 72.48-72.43mm

wheel tolerance: 72.54-72.59mm

I noticed alot of aftermarket wheels say they have a 72.6mm bore which is at the high limit of what I show here. I just purchased a set of wheels and I measured the hub bores with a bore gage and measured 72.69-72.72mm for all 4 wheels. If the spec I showed above is correct than these wheels are out of OEM spec. If the spec I showed above is incorrect then I need to know if my wheels are within spec.

e9x hub center bore is 72.56mm. I dont know the exact maximum wheel tolerance, but im assuming a difference of .13mm-.16mm from the hub size (as with your wheels) should be ok.

I think 72.6 (or 72.5) is short for 72.56.

I had tires/wheels mounted yesterday and there is zero vibration so I guess the hub bore on my new wheels are OK. I would still be interested in the OEM limits for those bores if anyone ever comes across it.
