FAQ
- What is the common lug pattern for the MG ZR?
- The MG ZR typically uses a 4 × 100 mm lug pattern, but it's important to verify the year-specific data for exact fitment.
- How does offset (ET) affect wheel fitment on the MG ZR?
- Offset determines the position of the wheel hub relative to the mounting surface; using the correct ET ensures proper clearance and handling on the MG ZR.
- Why is the center bore important for MG ZR wheels?
- The center bore must match or be larger than the hub diameter to ensure wheels mount securely and reduce vibration on the MG ZR.
