Bmw Wheels

[Colin Frolick]

if your wheels need the lugs to center it up, you've got issues.

how though, if you have tapered seat lug nuts, will the wheel NOT be centered by the nuts?

i had this 'problem' on my 02 mazda protege... i bought aftermarket wheels that vibrated badly once installed. i blamed it on a bad balance, the supplier said i needed 'hub centric rings' to center the wheel on the hub. i said bs, rebalanced the tires, and the problem went away. so on that car, with the current 17" aftermarket wheels, the wheels are not centered by the hub, but rather by the lug nuts.

the point about drum brakes is also valid, they do not have such a 'hub'. the rally II wheels on my pontiac don't even have a hub 'receptacle' or center bore as in the diagram above.
