Hub Centric Ring O.D. 78mm I.D. 72.6mm BMW
One set of 4 hub centric rings with O.D. (outer diameter) of 78mm and I.D. (inner diameter) of 72.60mm. These rings are made of high quality poly carbon. To determine proper fitment you need to do a couple of things. First you need to determine the center bore size, i.e. O.D. of the aftermarket wheel. Contact your wheel dealer if needed. Then find out the vehicle hub size, i.e. I.D. When these match our hub ring description, then they are the right size. These hub rings will fit the following cars and trucks
* Please note that All cars do not include Trucks and SUVs.
BMW: All BMW
Fitment and specs
- Outer diameter (O.D.): 78mm, matching the wheel's center bore
- Inner diameter (I.D.): 72.6mm, matching the BMW hub
- One set of 4 rings, one per wheel
- Made of high quality poly carbon
- Listed application: all BMW cars (the list does not include trucks and SUVs)
Press a ring into the center bore on the back of each wheel until it seats flush, then hang the wheel on the hub. A clean hub pilot helps the ring slide on squarely and makes lining up the bolt holes easier. The snug fit keeps the wheel precisely centered for a smooth ride.
Common questions
Will these fit my BMW?
The listed application is all BMW cars, paired with aftermarket wheels that have a 78mm center bore. If your hub measures 72.6mm and your wheel bore measures 78mm, this is the right set.
Do the rings go on the car or in the wheel?
In the wheel. Each ring presses into the wheel's center bore and stays there, filling the space between the 78mm bore and the 72.6mm hub.
