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).
- This bolt pattern is less common in our dataset. Verify wheel availability and hub specs before ordering.
