FAQs

Q1: What happens if the hub center bore does not match the axle flange? 

A: A mismatched center bore shifts the load from the hub face to the lug bolts. This can cause vibration, bolt stretching, hub cracking, and uneven bearing loading. Hub-centric rings may help only when the hub and vehicle specifications allow.

Q2: Why is PCD, offset, and hub bore important when selecting a wheel or hub? 

A: PCD ensures the wheel bolts align; offset affects suspension clearance and bearing load; hub bore ensures proper centering. Incorrect values can cause rubbing, vibration, premature bearing wear, or unsafe mounting.

Q3: Can a bent wheel rim cause symptoms similar to a bad hub bearing? 

A: Yes. A deformed rim can cause speed-sensitive vibration, tire seal leaks, and uneven wear. The difference is that rim-related vibration often improves after rebalancing or tire rotation, while bearing noise usually persists and may change during turns.
