Why Tyre Choice Matters for MG4
Electric vehicles like the MG4 produce instant torque and carry additional battery weight. This means:
- Faster tyre wear if low-quality tyres are used
- Increased importance of wet grip and braking
- Road noise is more noticeable (no engine noise)
Choosing the right tyre improves safety, comfort, and driving range.
Wheel Upgrade Considerations
When upgrading wheels on your MG4:
- Maintain overall rolling diameter within ±3%
- Ensure correct load rating (important for EVs)
- Keep offset close to factory spec (~45)
- Use hub-centric rings if required (67.1 mm CB)
Popular upgrade sizes:
- 18-inch: Best balance of comfort and performance
- 19-inch: Sportier look and handling (XPOWER style)
