Why is a hub centric ring necessary?

Aftermarket wheels typically have a larger centre bore than the vehicle hub. Without a hub centric ring, the wheel is not seated precisely – resulting in vibrations, steering shimmy and premature tyre wear. The hub centric ring fills this gap to the millimetre.
