What other years of Toyota Yaris iA have the same bolt pattern as the 2018?
The Toyota Yaris iA uses the 4x100 pattern from 2017 through 2018. Wheels from any of these model years are dimensionally compatible with the 2018, provided the offset and center bore also match.
Why is matching the 54.1mm center bore important for the 2018 Yaris iA?
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.

PCD stands for Pitch Circle Diameter, which is the same as the bolt pattern. For the 2018 Yaris iA, the PCD is 4x100.
Fitment Checklist Before You Buy Wheels
- Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).
