What is the center bore of a 2018 Toyota Corolla iM?
The factory center bore (hub bore) for the 2018 Toyota Corolla iM is 54.1mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.

Do 2018 Toyota Corolla iMs use lug bolts or lug nuts?
The 2018 Corolla iM requires 12x1.5 hardware. Check your specific trim to ensure you use the correct conical or spherical seating.
Why is matching the 54.1mm center bore important for the 2018 Corolla iM?
The 54.1mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
