If you’ve bought aftermarket wheels, you’ve probably used hub centric rings. They tend to inspire some extreme feelings among gearheads though. investigated the when and why for using then.
As general rules, Summit recommends using hub centric rings with all aftermarket aluminum wheels. You should not use them with factory wheels, steel wheels, any wheel with a push-through center cap, or any wheel with a non-machined center bore.
